Hello,
i starting a VPS with 5 GB ram limit
vzctl set 05 --swappages 0:2G --save
vzctl set 05 --kmemsize 5G --save
vzctl set 05 --vmguarpages 5G --save
vzctl set 05 --oomguarpages 5G --save
vzctl set 05 --privvmpages 5G --save
and i start my java aplication ( i starting with max 3 gb -xmx3g and xms756m ), and it's starting with about 1 GB of RAM and about 4 GB of ram in buffers ( don't know why ). And when the limit of aplication ram usage get 5 GB it's stuck the whole VPS.
Why buffered RAM is counting to the whole VPS ram?.
Is there any way to turn off that buffers?.

I mounted a directory as suggested in:

When I unmounted it the physical server hung,  syslog:

Is there a safe way to unmount?

The problem
We have an Adaptec 6805E card in an Intel Q67 / Core i7 server running Proxmox 1.9. Whenever and USB device is plugged in or removed (in our case the data center's KVM-over-IP console), there is a kernel error and the PCI bus hangs after that (extremely slows it down). It seems the Adaptec controller and the USB controller share the same IRQ.
Problem appears on all of our kernels, and only a hard reset solves the problem. Has anyone experienced this?
Others reported similar issues (not necessarily with OpenVZ kernel):
serverfault.com/questions/165717/apparent-irq-conflict-drivi ng-me-nuts-under-centos
forums.opensuse.org/english/get-technical-help-here/hardware /462213-irq-16-nobody-cared-try-booting-irqpoll-option-but-i rqpoll-causes-boot-failure.html
(remove spaces)
There are a lot of boot options regarding ACPI and IRQs.
help.ubuntu.com/community/BootOptions
We can't really test these on a production system. Anyone know what to do?

Hi,
A OpenVZ kernel 2.6.32-042stab062.2 is installed in several servers and each server running around 40 VPS which include CentOS 4 (32 bit), 5 (32 and 64 bit) and 6 (64 bit). It is observed that those Dell R410 servers is running smoothly but for HP DL360p G8 servers, a system time CPU will keep growing (refer to the attachment). The host CPU will drop to normal if the snmpd and autofs in VPS are restarted. Anyone facing similar problem? Thank you.
p.s. The server configuration as below:
R410: E5640 2.66GHz Quad x 2, DDR3 4GB 1333MHz Dual Ranked RDIMMs x 6, NL SAS 1TB x 2, PERC 6i RAID
DL360pG8: Xeon E5-2650L 8C x 2, DDR3 8GB 1333MHz x 16, 6G NL SAS 1TB x 4, Smart Array P420i (512MB FBWC)

Hi,
It looks like the latest RHEL 2.6.18 rebase was 2.6.18-308.8.2 from June of this year while the latest RHEL 2.6.18 kernel is 2.6.18-302.20.1
1) Is there any ETA on a rebase for RHEL 5 kernels?
2) Is there a policy about how often rebasing is done? Is it done only when there's a critical issue or is it done by request?
Thanks & all the best!

Hi,
Under a NAT setup (ip_forward enabled), I issued the following to create two containers -
vzctl create 101 --ostemplate centos-6-x86_64 --config basic --ipadd 192.168.3.101
vzctl set 101 --nameserver 8.8.8.8 --userpasswd root:xxxx --save
vzctl create 102 --ostemplate centos-6-x86_64 --config basic --ipadd 192.168.3.102
vzctl set 102 --nameserver 8.8.8.8 --userpasswd root:xxxx --save
I boot up the containers and connect to the first. The routing table shows as follows -
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.3.0 0.0.0.0 255.255.255.0 U 0 0 0 venet0
169.254.0.0 0.0.0.0 255.255.0.0 U 1002 0 0 venet0
0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 venet0
I change the masks on both containers to /24 (they were /32 by default).
(Still connected to the first container) I traceroute to the second container (192.168.3.102) I see the following -
traceroute to 192.168.3.102 (192.168.3.102), 30 hops max, 60 byte packets
1 192.168.2.200 (192.168.2.200) 0.045 ms 0.011 ms 0.010 ms
2 192.168.3.102 (192.168.3.102) 0.021 ms 0.014 ms 0.013 ms
I had assumed that both containers would be on the same network segment. I don't understand why the first hop is the HN? (192.168.2.200)? Wouldn't they be on the same virtual switch?
Thanks.

Hi,
[duplicate message, please refer message #48783]
I have install 2.6.32-042stab062.2 in several servers. Each server running around 40 VPS which include CentOS 4 (32 bit), CentOS 5 (both 32 and 64 bit) and CentOS 6 (64 bit). For those servers running on Dell R410, the host CPU and Memory usage is fine. However for those servers running on HP DL360p G8, it is observed that the host CPU system time is keep growing. It also observed that the CPU will drop if the snmpd and autofs daemon in the VPS is restarted therefore a script is wrote to restart all VPS snmpd and autofs daemon daily as a work around solution. Anyone has similar problem? Thank you.
Regards,
Kelvin

This is on a VZ container that is reporting low free memory. I can't figure out what is using it. Free used is not even close to ps rss totals:
# free -m
total used free shared buffers cached
Mem: 32163 31912 250 0 20 551
-/+ buffers/cache: 31341 822
Swap: 34239 9945 24294
# ps -eo pid,rss,comm --sort rss|awk '{SUM=SUM+$2}END{print "Total rss mem used:",SUM/1024,"mb"}'
Total rss mem used: 1472.67 mb
Its not the cache/buffers that are consuming memory. What is it?
The host is running ovzkernel-2.6.18-194.8.1.el5.028stab070.2.

I checked /vz/root/ and there was no 1001 directory. I rechecked the instructions and don't think I missed anything. Is the /vz/root/1001 directory supposed to be created automatically or do I need to create it somehow?

I'm new to networking.
I can gain internet via venet by setting the ip address to 192.16.1.x ; however, this doesn't allow me to set an ip address for each container.
I'm trying to point an ip address to use for a virtual container. I'm guessing I need to use veth?
What I'm Building:
I am using Proxmox to build a Virtual Server Environment with KVN and OpenVZ.
- I have Proxmox Virual Environment Installed with KVN and OpenVZ.
- I can create a virtual container with venet and gain internet access
My Problem:
- Deciding the best solution on how to enable each network with it's own IP address
- Trying to point an ip address to use for a virtual container.
I have a dedicated server that is being hosted by my provider and it is virtualization capable; however, I do not have experience beyond installing and managing lamp servers on a single IP address.
They have issued to me what appears to be 2 ethernet cards.
I have multiple ip addresses on one NIC (Eth0) that has a vlan with eth0:0, eth0:1, eth0:2, etc.
What is the best way to set up the network to point to my array of IP addresses to different containers or hardware virtualizations?
What should my files show?

Hi
Can any one help me in dumping the containers configuration file alone using vzdump util.
My Plane to backup a container:
1. Using vzdump util to dump conatiners configuration file alone, so that i can be huge in size and the time taken for the dump is also less.
2. Backup entire containers file using a file based backup util to a remote machine.
On restore:
1. Firs, I will restore the container using the dump file created using the vzdump util.
2. Copy the files available from the remote machine to its original path.
Regards,
Ravi S.

Hello,
I'm trying to build a setup where a container has a veth interface (bridged) and a venet interface (on a virtual machine only network).
This is what I want on the container:
eth0 (veth): 192.168.0.2/24, default gateway 192.168.0.1
venet0: 10.0.0.1/24, private only network
I set everything up but I have a problem with the routes. When I start the container they are like this:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.0.2.1 0.0.0.0 255.255.255.255 UH 0 0 0 venet0
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
0.0.0.0 192.0.2.1 0.0.0.0 UG 0 0 0 venet0
0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0
OpenVZ adds a default route via 192.168.2.1. I don't want it. If I remove the route manually at start everything works fine.
A simple solution could be to launch a script at start to remove the default route, but it doesn't look clean to me. I may be missing something.
Host node:
Debian Squeeze (2.6.32-5-openvz-686 #1 SMP Sun Sep 23 11:40:07 UTC 2012)
vzctl version 3.0.24
Container: debian-6.0-x86
IP_ADDRESS="10.0.0.1"
NETIF=" ifname=eth0,bridge=br0,mac=00:18:51:AA:43:18,host_ifname=vet h1000.0,host_mac=00:18:51:07:5A:D6 "
Thank you for any help!

Hello,
I have some address space from my ISP and the problem is he changed his behaviour -
some of reverse DNS entries are missing and my addres is not resolved to a name. The host networking is based on bridges and all outgoing connections are seen by external world as coming from host. Which by now is unresolveable and mails from it are not allowed to most other mail servers (I'm perceived as spammer).
somehow my virtual address is still right, so I want all my traffic from VE going out seen by external world to look like it goes from this IP and the IP of the host.
Is it possible and how? Any workarounds except kicking my ISP?
thanks.

Does anybody know if it's possible to download a file via the venet0 interface on the host? I ask because I have traffic shaping rules on our venet0 interface and I run an hourly job to test our network speeds but I would like to see the results as though it were a container with the traffic shaping and not the host with 2 GigE ports.

We are experiencing very high CPU usage on our server.

Hi ,
I am facing issue while creating container with latest templates of
ubuntu-12.04,SUSE12.2 & fedora templates .
When i try to create container i get following error
[root@openvz ~]# vzctl start 109
Starting container ...
Container is mounted
Adding IP address(es): 192.168.1.111
FATAL: kernel too old
Setting CPU limit: 10
Setting CPU units: 1000
Setting CPUs: 4
FATAL: kernel too old
Container start in progress...
I had fixed this error by adding
fedora-11 2.6.18
fedora-12 2.6.18
fedora-13 2.6.18
fedora-14 2.6.32
fedora-15 2.6.32
debian-6.0 2.6.32
ubuntu-12.04 2.6.32
fedora-17 2.6.32
suse-12 2.6.32
to /etc/vz/osrelease.conf
the below error was fixed but i could not ping the container .
What exactly i have to do to make latest added template work ?

I have OpenVz installed on Fedora 15. In my host OS I am able to install packages such as iperf.
However, when I'm inside a container (logged in a root on the container), I get the following error message:
yum -v install iperf
Config time 0.168
Yum Version: 3.2.29
Setting up Package Sacks
pkgsack time: 0.099
rpmdb time: 0.000
Setting up Install Process
Checking for virtual provide or file-provide for iperf
No package iperf available. Error: Nothing to do
The host OS and the container have the same set of repositories listed in /etc/yum.repos.d. Also there are no excludes in yum.conf, either on the host or the guest container.
What is really perplexing to me is I have this working on a different install of Fedora 15 with OpenVZ that I did a few months ago. I can't figure out what's different about this install.
In case it matters, all of this is running inside a VirtualBox VM i.e. I have a VirtualBox VM running Fedora 15 with OpenVZ installed on it.
Any help with this will be greatly appreciated---I'm at my wits end trying to figure this out. Thanks!

I'm using Proxmox, but I don't think that really matters since this should apply to other OpenVZ setups as well. Also, I've asked my question there as well but no one seems to be able to help me out. :/
My situation is the following: I have multiple OpenVZ hosts, each hosting a few containers. In Proxmox terms, they work together as a cluster and I can migrate containers from one host to the other without issues. Each host has a few network interfaces, the most important ones being the ones for the internal LAN (private IP space) and the external connection (public IP space). Only the interfaces on the internal LAN have IP's assigned to them, the external ones are used to bridge the veth interfaces and have no IP assigned to them.
Up until now I have been using veth interfaces in my containers since they all are under my control. Now however, I'm facing the "issue" where I have to set up a container for someone I don't trust. As such, venet seems to be a better option. The machine needs to have an external IP, but if I assign an external IP to this container, it doesn't work.
The reason why it doesn't is obvious, since venet uses the host's routing table and the host has no IP in the external network range, it doesn't know what to do with the packets.
The solution would be easy, just assign an IP in the external range on each host and be done with it. But this doesn't seem like a good solution to me, I'd like to be conservative about my IPv4 usage, so I hope there is another solution.
Does anyone have any pointers as to what I should look into? I'm a bit lost now. :/

Hey there,
I am completely new to OpenVZ and am running into difficulty when setting up my containers to recieve their ip addresses through DHCP rather than having them static.
I'm running CentOS 6.3, kernel Linux 2.6.32-042stab061.2 and the latest openVZ (as far as I'm aware).
I followed the guides:
wiki.openvz.org/Quick_installation
wiki.openvz.org/Basic_operations_in_OpenVZ_environment
wiki.openvz.org/Common_Networking_HOWTOs
to set up OpenVZ and the containers. However, when I'm going through the steps for DHCP supplied addresses in the third link, I come an error when I run the command:
[host-node]# ifconfig veth101.0 0
when I am met with:
SIOCSIFADDR: No such device
veth101.0: unknown interface: No such device
I followed the tutorials to the t, but yet I am stumped by this. I have tried searching any and all resources on the subject I could, but I'm still new to working with both Linux systems and OpenVZ itself.
Any information would be appreciated, or any links to information that I might have missed. (Also, any additional information I might need to give to help)

Hi Guys,
There is a confusing in my mind about "Alloc commit". Below "vzmemcheck" is showing my "Alloc commit" level is too high. But my server(64bit) has 250G RAM. Based on the formula given at " wiki.openvz.org/UBC_systemwide_configuration#Allocated_memor y ", I couldn't get the "1.72" anyway. How is the divisor of "RAM size + swap size" calculated here?
If using the 1.72 (Alloc commit) and 4.87(Alloc limit) to do a calculation, it seems 1G RAM size (32bit limit) is still using here as the divisor.
Any idea? Thanks in advance.

Sep 30 00:11:11 kraken kernel: ----------- [cut here ] --------- [please bite here ] ---------
============================================================ ====
Our server runs in CentOS 5.8.
The Opven VZ kerenel version is 2.6.18-308.8.2.el5.028stab101.1
The server has 64GB RAM. We have replaced the RAM thinking that it was due toa faulty memory module, but still the issue is persisting.
Every-time I am getting the same error in var/log/messages.
Can anyone help me with this ?

Just a heads up to all whom this might concern - libcgroup from openvz repo is now replacing the original libcgroup on RHEL 6.
This kind of invasive OS changes should be announced somewhere, really. Just a silent drop in the repo isn't a good way to introduce such packages.
Is there a specific reason for this upgrade? I know libcgroup is being provided for RHEL 5, but why is it now also replacing the existing RHEL 6 package? Is there a specific functionality that's missing in the original?
Wouldn't perhaps a separate RHEL 5 / 6 repo be the right thing to do here in the first place? So ploop on RHEL 5 could perhaps be obsoleted, libcgroup properly handled, etc...?

Hello for all..
I ever got IO problems with OpenVZ, and this is very difficult to see what's really killing your server.
For an example, today, my server load raised to about 200:
01:40:01 PM 12 3337 156.16 134.98 84.33
01:50:01 PM 13 3392 166.27 162.10 122.29
02:00:01 PM 17 3356 222.48 213.78 166.39
02:10:01 PM 13 3150 193.64 193.30 176.32
I tried to get what's happening with top, atop -dD, free -m, vzmemusage, and another tools, but I can't, and when I was at the TOP, I saw a process: rm -rf
I killed this process and the server load lowered to 4~7.
02:40:01 PM 29 2364 4.38 7.10 44.34
02:50:01 PM 37 2526 7.93 6.68 26.26
03:00:01 PM 38 2404 5.21 6.10 16.73
I don't know what to do! Because a simple rm -rf basically killed my server, so, I don't think that this is good.
I saw too that the server swapped 600 kb while this, even if there were memory free.
See my free -m now:
total used free shared buffers cached
Mem: 32112 29653 2458 0 1884 18263
-/+ buffers/cache: 9505 22606
Swap: 3906 3 3902
This cached mem don't should be drop when the real mem really need?

Hi everyone,
I want to exclude many path with vzdump (in proxmox context) because the load time is too long.
Command : vzdump --exclude-path "/home/.+" -dumpdir "/var/vzbackup/" 100
When i start this command, the path folder are not exclude in the tmp folder.
Do you have any idea?
Regards,
Manu

Hello,
I'm looking for an ubuntu 12.04 minimal template. The template I found for Ubuntu 12.04 is very fat with many open useless services opened by default (samba!?)
Anybody tried to slim down this template or created a new minimal template from scratch like the ones available for other OS?
Thanks.

Hello!
I am new to OpenVZ but I cant get my head around this problem: whenever I stop a VE my connection on my HN disappears. I get the following message in my messages log:

Any idea how to stop this from happening? I am clueless

I have a node that just started crashing about a week ago. Only thing that changed is that I have added a couple new VPS's. Memory usage is still well below total RAM. Nothing in log files.
Only thing I see that is a bit suspicious is:
Route hash chain too long!
Adjust your secret_interval!
lo: 5 rebuilds is over limit, route caching disabled
After lots of googling this problem was supposed to be fixed many kernels ago but apparently isn't. I did change my secret_interval from the default of 600 to 300 afterwards but from what I have read it's not really a fix.
Any other ideas what could possibly be going on? As far as I can tell the kernel is not crashing. Just becoming non-responsive (network and maybe Disk I/O) but still responsive enough for a soft reboot as opposed to a hard reset.
I was running RHEL5 028stab099.3 x64 for months before this started happening. Since it has happened twice in the past week I did yum update of everything including the latest kernel as of this post which is RHEL5 028stab101.1 because I don't know what else I could possibly do. Right after I rebooted into that kernel I almost immediately got the
route hash chain too long!
Adjust your secret_interval!
lo: 5 rebuilds is over limit, route caching disabled
So that definitely didn't change. Not convinced that has anything to do with it because I am pretty sure I was getting that error way before these lock ups started happening.

For a running 32-bit openvz install that is using the PAE kernel in RHEL5, is it safe to update the kernel to the ENT version? Any issues doing this with a live system running multiple containers?
Running into some lowmem issues and it seems the enterprise kernel with 4/4 split would alleviate these.

Hey there.
First of all, sorry for my bad englisch, i'm giving my best. I'm from austria.
I have a dedicated server in a datacenter with 2 IP subnets (/28), i'm hosting some VPS with openvz on it.
I've entered all the infos for the first subnet into the ifcfg-eth0, but how can i enable the second subnet? It has a different gateway. All things i found via google is to create a ifcfg-eth0:0, but then i will lose 1 ip for the host?
Do you have a idea?
Best regards.

On my openvz host node, I have blocked port 25 using the following command ..
iptables -A FORWARD -j DROP -p tcp --destination-port 25
This is fine, but it blocks the port for all the containers.
Therefore, I have tried something like this, although it is listed in iptables -L, the connection cant be made. (Tried to check via telnet)
iptables -I FORWARD --source 7.5.4.7 --protocol tcp --destination-port 25
OR
iptables -I FORWARD --source 7.5.4.7 --protocol tcp --destination-port 25 -j ACCEPT
Any idea what is wrong?
PS. The block command is in the end, and nothing is below it. So this shouldn't be a problem.
Thanks
