(proxmox 1.6 here. Linux vpsnode01-nk 2.6.32-4-pve #1 SMP Thu Oct 21 09:35:29 CEST 2010 x86_64 GNU/Linux )
From within OpenVZ containers I see the private space (rfc 1918) address
of the drbdlink interface as first hop and not of my publicly connected interface (eth0/vmbr0)
From within container a traceroute looks like this:
/# traceroute -n www.heise.de
traceroute to www.heise.de (193.99.144.85), 30 hops max, 40 byte packets
1 10.0.23.2 0.033 ms 0.007 ms 0.007 ms
2 217.x.99.13 2.206 ms 2.243 ms 2.285 ms
why is the first hope (the hostnode) displayed with the private address of drbdlink interface?
(I would expect it to be 217.x.50.8 at least that's what I want)

I have just installed Ubuntu 10.4 as my HN on my new sandy bridge based i5
This required compiling kernel-2.6.32.14-ovz32 to tame the sandy bridge chipset - no kernel earlier then 2.6.27 has a chance of this.
(I just noted the ovz32 part of the name - does that mean its 32 bit ?)
All works well (mostly): the HN is stable and tweaked according to instructions.
Proof of this is that ubuntu 10.4 CT works perfectly with full networking)
However, the centos5 CT does not start the network service. instead it reports that both lo and venet0 do not seem to be present.
ifconfig returns null
iptables -t nat -L
cant initialise and suggests that I may need to use insmod or upgrade the kernel.
Is this an incompatibility between the HN 2.6.32 kernel and the earlier centos kernel?
Thanks in advance

We are trying to make a NFS mount from the HN appear within a container.
We got it working by adding mount and umount scripts. However we are having some issues.
1.mount
#!/bin/sh
source /etc/vz/vz.conf
source ${VE_CONFFILE}
mount -n --bind /nfs/apps/wiki ${VE_ROOT}/nfs/webroot
1.umount
#!/bin/sh
echo "UMOUNT IS RUNNING" <-- for testing see below
source /etc/vz/vz.conf
source ${VE_CONFFILE}
umount ${VE_ROOT}/nfs/webroot
The problem I am seeing is that the umount script is sometimes getting called on startup and I believe
it's causing the mount to not appear in the container. Whats weird is if I comment out the umount
line I never see my echo statement ran on startup. However with umount uncommented I always
see the echo statement. This seems like strange behavior that I can't explain. I was hoping someone
else had some ideas.
Normal stop start with mount/umount scripts:
# vzctl stop 1
Stopping container ...
Container was stopped
RTNETLINK answers: Network is unreachable
UMOUNT IS RUNNING
umount: /vz/root/1/nfs/webroot: not mounted

NFS mount will only be there if I do a sevice vz restart. After that a stop/start will not mount my NFS mount in the container
From the "UMOUNT IS RUNNING" you can see that it is running the 1.umount script on start and stop
However, If I comment out the umount stuff it only runs that script on stop:
# vzctl stop 1
Stopping container ...
Container was stopped
RTNETLINK answers: Network is unreachable
UMOUNT IS RUNNING
Container is unmounted
_[/etc/vz/conf]_(root@a.apps)_
# vzctl start 1

My NFS Mount is there.
So if I comment out the 1.umount script everything works.
Im pretty sure I want to be able to umount things on shutdown.
Any ideas whats going on?
# rpm -qa |grep vzctl

Hello,
i am searching for a solution to get cpu scheduler of rhel5 into a new kernel rhel6.
I want to limit cpu cores per virtual server(important) and also limiting cpu limit with cpulimit. Users need exclusive cpu cores. Is it possible to modify a rhel6 kernel to get these features?
Thanks for every help!

Hi,
I encounter problems when I try to run GStreamer and PulseAudio within OpenVZ container. I got errors like
shm_open() - function not implemented etc.
mmap()ing memory also fails.
Is SHM and mmap disabled in the OpenVZ kernel or maybe I am doing something wrong?

hi,
i am running debian queeze and 2.6.32-5-openvz-amd64 kernel.
Debian is running well as virtual server.
SuSE ( taken precreated suse 11.3 image from openvz download page )
is starting:
Starting container ...
Container is mounted
Adding IP address(es): 10.1.2.3
Setting CPU units: 10000
Set hostname: susetest
File resolv.conf was modified
Container start in progress...
It shows up in the list privided by vzlist for 2-3 seconds and then it just vanishes from the vzlist provided list.
So the suse vps can not be started.
In the config i filled in
OSTEMPLATE="suse"
should be right.
Is there any specific trick or any idea where to search ?
Its all plain installed squeeze.
Thank you

I have OpenVZ containers running on TOP of a DRBD block device.
Looking at these 2 files:
grep chkconfig /etc/init.d/vz
# chkconfig: 2345 96 88
grep chkconfig /etc/init.d/drbd
# chkconfig: 2345 70 08
I can see that it is expected to see the shutdown sequence like this:
/etc/rc0.d/K08drbd
/etc/rc0.d/K88vz
This seems like an error to me.
K08drbd tries to unmount the filesystems BEFORE K88vz has shutdown the containers.
To me, OpenVZ shutdown should start MUCH earlier, something like this:
grep chkconfig /etc/init.d/vz
# chkconfig: 2345 96 05
Any feedback is welcome.

My NH is networkless. The containers are networked via NETDEV and I can add and remove them from different networks with brctl from the HN.
I would like to block all traffic of a specific user.
From the container I would do it like this:
iptables -A OUTPUT -m owner --uid-owner {UID} -j REJECT
Is there a way to do that from the HN?

Hi all,
I wanted to know if some body has always done this configuration (because I tried to done it)
I've two RHEL 5.5 servers (HN)with openvz (ovzkernel-2.6.18-238.9.1.el5.028stab089.1.x86_64.rpm)
I've follow this howto HAclusterwithDRBDandHeartbeat on the wiki with drbd 8.3.10,pacemaker-1.0.11 and heartbeat-3.0.3.
Configuration seems OK
I've a VE with LAMP (Apache + php + mysql)
Actually, I've done two drbd "FS" /vz and /data, on /vz there are OS + binary for (apache, php, mysql ...) on /data there are data for apache and mysql database.
My question is how the "primary" VE must to migrate on the secondary HN when the first HN failed ?
Must I need to use drbd only for /data and need to setup an other VE on the secondary HN it use only data ? Or must must I need to used drbd for /vz and /data ? I wanted to done a fail-over configuration.
thanks in advanced for your clarify answer.

We had load spikes issue on our server having OS ubuntu 9.04 with kernel 2.6.24-7-pve and pve-manager 1.3-1. Load used to reach to 4.0-5.0 multiple times in a day, without any Virutal Container running on the server.
To resolve load spike issue, we have upgraded the system to proxmox kernel 2.6.24-10-pve and pve-manager: 1.5-8, but still same issue persist, even though there was no Virtual Container running.
However, when we booted the system with the Ubuntu kernel 2.6.28-11-server the load average on the server is below 0.2.
Server is having 2 Intel Quad Core i7 Xeon processor (Hyperthreaded so the OS sees a total of 16 processors) and 72GB DDR3 Memory.
Please help me to figure out the issue and let me know if you need more information.

Hi!
We need very simple reboot web panel to end users-administrators of OVZ containers.
We use Puppet to manage HardwareNode, and don't have big and coplex web-based management of OpenVZ.
But, end-users need simple panel.
I may use php script, writed myself, but... i think, it's not true, if is any web panel, with good design and without security bugs..

Hi, I'm using Openvz on a Debian Squeeze system and created a container to deploy a squid server (also with debian squeeze template).
When I mark the ip address and port of my proxy server in the browsers of the clients it works perfectly, but I need to use transparent proxy so I created a rule on my firewall to redirect connections on the port 80 to my proxy server: iptables -t nat -I PREROUTING -i eth0 -s 192.168.100.0/24 -p tcp -m tcp --dport 80 -j DNAT --to-destination 192.168.100.249:3128
This redirection does not work to my squid server running on a container, but works if I redirect to my old proxy server running on a physical machine. What have I misunderstood?
My best regards,
Fabio S. Schmidt

Hello,
We've experienced this same behavior yesterday and today (on different hardwares). I am not sure but I believe we were migrating the same VE (yesterday from ServerX to ServerY and today from ServerY to ServerZ).
After doing a live migration of a container we saw on dmesg:
DFS1339: resuming daemon started
DFS1339: Retrying delayed mount in 16 seconds
DFS1339: Retrying delayed mount in 32 seconds
Not sure if this was related, but I tried to restart this container as soon as I saw these messages and the hardware crashed while I was seeing:
"vzctl restart 1339
Restarting container
Stopping container ...
"
I believe we got a kernel panic since it rebooted itself (we have panic=10) and server got back few minutes later.
Any hints?

I have the following setup:
A server, that has 16 different subinterfaces eth1:1-eth1:16. This was designed by someone who still has control over this area, and I have minimal access to changes with regards to this configuration.
I'm attempting to configure eth1:16 for use with OVZ. It appears as though I have netdev configured incorrectly, and the error is causing the template start to fail.
My guess is it has to do with the subinterface. I can't find any information about using subinterfaces in the users guide.
Question: How do you configure an network interface with a subinterface.
It looks like venet or veth might be able to solve this, but I'm not familiar with their configuration, and not sure how to use it entirely. I didn't see much help in the user guide.
Data:
Below is the trace when trying to start the server.
Adding IP address(es): 10.1.1.101
UB limits were set successfully
Unable to add netdev eth1:16: No such process
Container start failed (try to check kernel messages, e.g. "dmesg | tail")

I think I've experienced this problem for nearly one year.
I typed this (IP is fake, just for demo):
# vzmigrate -v --online 50.65.153.78 869
OPT:-v
OPT:--online
OPT:50.65.153.78

Error: Failed to load 2nd level quota
Resuming...
after searching a lot:
I tried:
# vzctl set 869 --quotaugidlimit 100 --save
And it is no use and still the same 2nd level quota problem.
I also tried turning off quota:
# vzctl stop 869
# vzquota drop 869
# vzctl start 869
And then migrate again, it doesn't work and still the same 2nd level quota problem.
Both old HN and new HN run the same kernels:
Linux demo.com 2.6.18-194.26.1.el5.028stab081.1PAE #1 SMP Thu Dec 23 21:08:29 MSK 2010 i686 i686 i386 GNU/Linux
I followed exactly what it is said here:
wiki.openvz.org/Migration_from_one_HN_to_another
Your help will be highly appreciated.

Hi Im trying to backup with the ezvzdump script over a network.
But when the script suspends the VE oracle breaks and needs a restart.
Is this a known problem, is there anything I can do against this ?

Hello,
I have one OpenVZ host server (created before from somebody else) with only one NIC (eth0) and one venet (venet0) and public IP address (67.55.98.6 for example) assigned to this NIC. And of course several containers with own public addresses. (101 with 67.55.98.10; 102 with 67.55.98.11, 67.55.98.12; 103 with 67.55.98.13, 67.55.98.14; 104 with 67.55.98.15for example, etc)
Now I want to add second NIC (eth1) to the host machine with private IP address (192.168.1.200 for example). For several of the guest machines I want to change the IP address from the public one to the private one (for 101 and 104 for example) and of course all the traffic for these two machines should go through the eth1 and 192.168.1.1 for gateway in this scenario. From the rest of the guest machines I want to keep the existent configuration.
Please advise me how to configure this. I searched for information, but actually I didn't find anything suitable.
Thank you in advance!

Hi folks.
I just joined in this forum... I'm newbie with Snort running in virtual machines and I have a doubt.
I've googled many sites, lists, but I'm lost about a weird error.
I've installed and configured the snort 2.9.4 but I can't start it.
This is my interface:
venet0:0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00

UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1
I did a test with snort:
snort -vv -i venet0:0

Commencing packet processing (pid=5776)
Can't acquire (-1) - cooked-mode frame doesn't have room for sll header!
And the snort can't start.
I don't know which kind of Linux is running on the parent host.
I've installed the CentOS 5.5, and this is output of uname:
uname -a

Someone can help me?
Thank in advance.
Regards,
Ivani

Hi,
I am trying to do a simple network using NAT.
My CT0 have a public IP and I want to share it with 3 VM, I have followed this : wiki.openvz.org/Using_NAT_for_container_with_private_IPs
CT0 public IP : X.X.140.213
CTX Network : 192.168.0.0/24
I can ping my VM and I can access my VM using SSH through NAT but VM can't ping anything on the internet. I think this is a strange behavior.
Here is my sysctl :
net.ipv4.conf.default.forwarding = 1
net.ipv4.conf.default.proxy_arp = 0
net.ipv4.ip_forward = 1
net.ipv4.conf.all.rp_filter = 1
kernel.sysrq = 1
net.ipv4.conf.default.send_redirects = 1
net.ipv4.conf.all.send_redirects = 0
Iptables on CT0 : (very unsecure for testing)
#!/bin/sh
iptables -t filter -F
iptables -t filter -X
iptables -t filter -P INPUT ACCEPT
iptables -t filter -P FORWARD ACCEPT
iptables -t filter -P OUTPUT ACCEPT
iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -o eth0 -j SNAT --to X.X.140.213
iptables -A FORWARD -s 192.168.0.0/24 -j ACCEPT
iptables -A FORWARD -d 192.168.0.0/24 -j ACCEPT
iptables -A INPUT -i venet0 -j ACCEPT
# SSH CT1 (port 2221)
iptables -t nat -I PREROUTING -p tcp -d X.X.140.213 --dport 2221 -j DNAT --to 192.168.0.1:22
iptables -I FORWARD -p tcp -d 192.168.0.1 --dport 2221
# SSH CT2 (port 2222)
iptables -t nat -I PREROUTING -p tcp -d X.X.140.213 --dport 2222 -j DNAT --to 192.168.0.2:22
iptables -I FORWARD -p tcp -d 192.168.0.2 --dport 2221
By the way I set up CT using OpenVZ Web Panel.
What do I missunderstand ?
Thanks.

Hello,
Is there a particular reason that the maxlat field in /proc/vz/vestat isn't updated no matter what happens in a container/ve?

Hi *,
trying to install Oracle 11g on a Centos-5-64 container, I run into a peculiar problem: the kernel parameters "semmsl" and "semopm" are too small (100/32) - inside the container, although it's big enough (250/256) on the HN:
On VN:
[root@dhsrv1003vz ~]# ipcs -l
------ Shared Memory Limits --------
max number of segments = 4096
max seg size (kbytes) = 524288
max total shared memory (kbytes) = 8388608
min seg size (bytes) = 1
------ Semaphore Limits --------
max number of arrays = 128
max semaphores per array = 100
max semaphores system wide = 32000
max ops per semop call = 32
semaphore max value = 32767
------ Messages: Limits --------
max queues system wide = 7992
max size of message (bytes) = 8192
default max size of queue (bytes) = 16384
On Host:
nwivz:/# ipcs -l
------ Shared Memory Limits --------
max number of segments = 4096
max seg size (kbytes) = 524288
max total shared memory (kbytes) = 8388608
min seg size (bytes) = 1
------ Semaphore Limits --------
max number of arrays = 1024
max semaphores per array = 250
max semaphores system wide = 256000
max ops per semop call = 256
semaphore max value = 32767
------ Messages: Limits --------
max queues system wide = 7992
max size of message (bytes) = 8192
default max size of queue (bytes) = 16384
nwivz:/#
Is there a way to configure the VM so it uses the settings of the HN?
Thanx,
Joachim

Hi,
I recently upgraded my OVZ kernel, and had to recompile the DAHDI driver for Asterisk on the host machine, but I get to following error now:
In file included from /usr/src/asterisk/dahdi-linux-complete-2.4.1+2.4.1/linux/dri vers/dahdi/xpp/xpd.h:31,

When I do the same compile on the standard CentOS kernel, or a previous version of OVZ, it compiles without any errors.
Can anyone help out please.
OS: Centos 5.5
DAHDI version: 2.4.1
OVZ Kernel: 2.6.18-238.5.1.el5.028stab085.3
Software Package installed for compile:
ovzkernel.x86_64
ovzkernel-devel.x86_64

I am running RHEL6 042test008.1, but the parameter for specifying the number of CPUs within a container doesn't seem to work.
If I set it to something like 1, I still see all node CPUs with the 'top' command, whereas I would expect to see 1 CPU.
vzctl.log shows the expected output, i.e. "Setting CPUs: 1".
Is this a known issue? I searched the forum but didn't find any applicable posts.

Hello,
I need to setup backup solution. The fastest way is to just rsync update files to backup server. But the problem is, that I need to reinitialize quota when trying to start container using just rsynced files from running HN. Reinitializing quota takes a lot of time. Is it possible to turn off quota while starting container, and then turn it on, on new running container.
vzdump isn't the solution, cause it takes a lot of time to dump and then to transfer files to backup server. Maybe there is any solution to run dump only changed files to already existing tar?

Hi,
I have a VE with 300+ IPs assigned to it. The start process ( not VE boot ) takes about 15 minutes.
The process that takes time is /bin/sh /usr/lib/vzctl/scripts/vps-net_add
Is there a way to make this run in background? I usually don't need all IPs upfront, only the first one.
Thanks!

I want to execute a perl commando using the exec command but I cannot get the syntax correct.
vzctl exec 12345 "/usr/bin/perl \-pi\~ \-e \'\$\_=\"servername=my.hostname.here\\n\" if /\^servername=/\' /usr/local/directadmin/conf/directadmin.conf"
When i execute the above commando i get the following error:
Can't find string terminator "'" anywhere before EOF at -e line 1.
I tried several options and combinations but i cannot get it correct, it keeps giving an error.
The following command works within the VZ container itself:
/usr/bin/perl -pi~ -e '$_="servername=my.hostname.here\n" if /^servername=/' /usr/local/directadmin/conf/directadmin.conf
So this command should be executed from the hardware node (outside the VZ container) using the vzctl exec command.
Can someone see the error here?
Thx for any help.

Hi,
I am trying to set up an ipvs server into a VE.
I'am following the wiki:
But it's not enough.
To do that, i set up a network configuration like this:
On ipvs VE = VE1, I configure a veth device with mac address:
NETIF=" ifname=eth0,mac=00:0C:29:CA:90:9B,host_ifname=veth170002.0,h ost_mac=00:0C:29:3F:6D:E0 "
On hardware node, i configured a bridge device:
vzbr0 Link encap:Ethernet HWaddr 00:0C:29:3F:XX:XX
inet addr:XX.XX.XX.XX Bcast:XX.XX.XX.XX Mask:255.255.252.0

collisions:0 txqueuelen:0
RX bytes:11312394 (10.7 MiB) TX bytes:2568442 (2.4 MiB)
with interfaces:
brctl show

vzbr0 8000.000c293f6de0 no veth170002.0
bond0.1031
and bond0.1031

collisions:0 txqueuelen:0
RX bytes:115739325 (110.3 MiB) TX bytes:100705549 (96.0 MiB)
I switch on the capa NET_ADMIn on VE.
The same for applicative VE= VE2. I added a VIP on lo mode. XX.XX.XX.1
I installed a ipvs server onton VE1. And my rules is loaded:
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP XX.XX.XX.1:ldap rr
-> XX.XX.XX.XX:ldap Route 1 0 0
So, VE1 is listening on VIP on HME interface, like eth0.
On my VE2, i'am listening on port 389 on VIP.
But,
I 'm not available to do a telnet on VIP:389 since another HWN
[root@HWN ~]# telnet XX.XX.XX.1 389
Trying XX.XX.XX.1...
telnet: connect to address XX.XX.XX.1:389 Connection refused
My keepalived conf:
global_defs {

}

smtp_server ZZ.ZZ.ZZ.ZZ
smtp_connect_timeout 30
}

}

}
}
}
If you have an idea, please help me
Thx ahead.

I have a suggestion. How about a "lint" command to test/fix containers for compatibility? I don't know how many of you are like me but I run Fedora containers and every release or so they change something the breaks OpenVZ.
I upgrade with Yum
So - most of these things are easily fixed by deleting/modifying a few simple files. It would be nice to have a utility that did that for me so that I could run vzctl lint <veid> and it would diagnose/fix the container.

Hi,
I want some advice to the best way to configure my server:
i have 17 small vps with 256mb with very small usage and 1 vps running cpanel that i want to give most of resoucers.
my server: dual Intel Harpertown E5405 with 12gb ram.
kernel version: 2.6.18-194.26.1.el5.028stab081.1
i have solusvm installed and this server is for private use so i don't have problems with abusers.
My question is how to optimize resouces to run cpanel with best performance because i'm seen php scripts and mysql to run very slow inside the vps with cpanel.
solusvm (running php too) runs very very fast so i'm thinking thats the problem is because my vps to run cpanel is configured with small resources.
here the config for that vps:
guaratee ram: 4096
burst: 6144
CPU Units: 10000
cpu cores: 16
CPU %: 4400
io/priority: 5
some tip to fix this issue?
thanks,
stacker

Hello, I am currently running the atkov patch on 2.6.32.11.
I have attempted to install the feoktistov patch to vanilla sources with no success, I have tried 2.6.32, 2.6.32.27 through 2.6.32.32.
I most cases I could not see openvz in the virtualization section in menuconfig. 2.6.32 could not even run menuconfig.
I am on Debian, but the dist supplied kernels do not boot so I have been forced to compile my own.
Can someone document the proper steps for patching with feoktistov under a kernel version newer than 2.6.32.11?
Thanks All!

Hello,
I am using the new debian release and the kernel 2.6.26-2-openvz-686.
When i create a container, I put in numer of cpu's.
I use CPUS et CPULIMIT parameters and with HTOP command i can see all the cpu offered by the hardware.
Is there anybody who know if it is possible to limit this ressource ? And which kernel has to be used on Debian to limit it ?
Regards
