Hi all,
i read many many posts about vserver VS OpenVZ so here i am Smile

I would like to try it but i am not able to compile kernel after patch.

I receive a lot of hunks during patching kernel and after make menuconfig when i did make bzImage ld error and die.

I read that kernel patch was tested only on redhat and CENTOS..

There is no way to install OpenVZ on a debian system ?


Thanks in advance

Probably you patch kernel-source of wrong version or it from your distr.

You should get kernel from http://www.kernel.org 2.6.8 )
and apply patch to it, or get already patched, full version from here:
http://download.openvz.org/kernel/022stab061.1/ovzkernel-2.6 .8-022stab061.1.src.rpm

My fault.

I downloaded 2.6.0 instead of 2.6.8

I am really sorry to let you loose time about my errors.

First I hope that OpenVZ patch applied well, there was no rejects and so on.

Second, it is hard to tell what's wrong without having your .config. Note that some combinations won't work (see bug #52).

So, you'd better take one of the existing configs from http://download.openvz.org/kernel/current/configs/ and put is as .config to your source tree, then run make oldconfig and compile the kernel as usual. Or check bug #52 for known issues and change config options accordingly.

mmm
kernel works but after i install from source vzctl i receive this error when try to start /etc/init.d/vz

/etc/init.d/vz: line 26: /etc/rc.d/init.d/functions: No such file or directory

Anyway i did a find to try where possible file functions is and this are results:

/usr/lib/vzctl/scripts/vps-functions

i need to use this one instead or there is another solution?

I read also this thread:
http://forum.openvz.org/index.php?t=tree&th=184&mid= 822&&rev=&reveal=
but i cant still solve problem.

What do you suggest ?

Debian needs its own init script, since it is not like RedHat or Gentoo. Currently we have one for RedHat-like systems (included into vzctl rpm) and the one for Gentoo systems (available from Gentoo portage).

So it needs to be written...even by you, if you take a look at other scripts from the same directory and see what do they do to print success/error messages and so on. I can definitely help.

Ok looklike it works now.

I am actually trying to create a vs debian.

Anyway i had to add following to your init script:

(from functions file taken from redhat 9)

Quote:


#. /etc/rc.d/init.d/functions

action() {
STRING=$1
echo -n "$STRING "
shift
#initlog $INITLOG_ARGS -c "$*" && success $"$STRING" || failure $"$STRING"
rc=$?
echo
return $rc
}

echo_success() {
[ "$BOOTUP" = "color" ] && $MOVE_TO_COL
echo -n "[ "
[ "$BOOTUP" = "color" ] && $SETCOLOR_SUCCESS
echo -n $"OK"
[ "$BOOTUP" = "color" ] && $SETCOLOR_NORMAL
echo -n " ]"
echo -ne "\r"
return 0
}

success() {
# if [ -z "${IN_INITLOG:-}" ]; then
# initlog $INITLOG_ARGS -n $0 -s "$1" -e 1
# else
# silly hack to avoid EPIPE killing rc.sysinit
trap "" SIGPIPE
# echo "$0 \"$1\" 1" >&21
trap - SIGPIPE
[ "$BOOTUP" != "verbose" -a -z "$LSB" ] && echo_success
return 0
}
#Disable everywhere initlog command cause i didnt find any #initlog package for debian.



Of course i could also create a file functions with these functions and let your script include it.

I used your binary packages to do that.

So .. i am checking and let you know if it works totally or not.

It looks like venet0 device is not up.

It happened because in the stuff you added to /etc/init.d/vz there is a shell function called 'action' which should execute the command -- and you commented out that actual command execution:

 #initlog $INITLOG_ARGS -c "$*" && success $"$STRING" || failure $"$STRING"


Please put something like this instead of the above line:
$* && success $"$STRING" || failure $"$STRING"


so the actual code passed into the function will be executed.

Alternatively, to set up venet0 device, you have to do the following:
modprobe vznetdev
modprobe vznet
ip link set venet0 up
ip addr add 0.0.0.0/0 dev venet0
sysctl -w net.ipv4.conf.venet0.send_redirects=0

I just need this on functions file.


That's my functions file if you need:

Quote:

vps:~# cat /etc/init.d/functions
action() {
STRING=$1
echo -n "$STRING "
shift
$"$STRING"
$* && success $"$STRING" || failure $"$STRING"
rc=$?
echo

echo_success() {

echo -n "[ "
[ "$BOOTUP" = "color" ] && $SETCOLOR_SUCCESS
echo -n $"OK"
[ "$BOOTUP" = "color" ] && $SETCOLOR_NORMAL
echo -n " ]"
echo -ne "\r"
return 0
}

success() {

[ "$BOOTUP" != "verbose" -a -z "$LSB" ] && echo_success
return 0
}

First, you should use *real* IP address for you VPS, if you want to be able to access internet from it.

Second, you probably missed setting nameserver inside a VPS.

It is not clear whether you should use NAT or not - I do not know your network setup...

Some networking problems are caused by the fact that ppl forgot to enable IP forwarding (net.ipv4.ip_forward = 1). For details, see Quick Install document.

So I assume you use NAT somethere on the gateway...no need to NAT at OpenVZ box then.

As you can see list link report eth and not eth0 or something like that.
I dont know if it's a problem or not but i can ping and connect to vps server(1.1.1.11) from vps guest(1.1.1.7) but i am not able to reach other host on my lan neither reach internet.

please, check that

Outside vps guest this is route:

and this is ip addr output:

this is sysctl.conf:

net.ipv4.ip_forward = 1
net.ipv4.conf.default.proxy_arp = 0
# Enables source route verification
net.ipv4.conf.all.rp_filter = 1
# Enables the magic-sysrq key
kernel.sysrq = 1
# TCP Explict Congestion Notification
#net.ipv4.tcp_ecn = 0
# we do not want all our interfaces to send redirects
net.ipv4.conf.default.send_redirects = 1
net.ipv4.conf.all.send_redirects = 0


That's all


Where i am wrong ?

Have you actually applied the setting from /etc/sysctl.conf to the running kernel? I.e., what does 
cat /proc/sys/net/ipv4/ip_forward
shows you?

For the troubleshotting, can you please post the output of these two commands here?

/sbin/ip link list | egrep -v -E 'LOOPBACK|NOARP|SLAVE'

/sbin/ip link list | egrep -v -E 'LOOPBACK|NOARP|SLAVE' | awk '/^[0-9].*:/&&/UP/ {print substr($2, 0, length($2)-1)}'



The output is eth but it should be eth0.

The solution is to change the awk script that the output is eth0.

/sbin/ip link list | egrep -v -E 'LOOPBACK|NOARP|SLAVE' | awk '/^[0-9].*:/&&/UP/ {print substr($2, 0, length($2))}'


regards
ralph

phlar,

The problem is if I execute the command you give on my Fedora Core 4 box, it will give me 'eth0:' i.e. with comma which should be stripped off. Looks like debian awk and fedora core awk do not agree on the syntax of substr.
[kir@kir ~]$ /sbin/ip link list | egrep -v -E 'LOOPBACK|NOARP|SLAVE' | awk '/^[0-9].*:/&&/UP/ {print substr($2, 0, length($2))}'
eth0:


So what I propose is to use this construct:
/sbin/ip link list | egrep -v -E 'LOOPBACK|NOARP|SLAVE' | awk '/^[0-9].*:/&&/UP/ {print $2}' | tr -d ':'


It should work fine everythere

Yes, i suspect that the debian-awk starts not at the index zero. The first position is 1 not 0. And it is possible to start at positions lower than zero. Confused 

openvz:~# echo "test"|awk '{print substr($1,1,4)}'
test
openvz:~# echo "test"|awk '{print substr($1,0,4)}'
tes
openvz:~# echo "test"|awk '{print substr($1,-1,4)}'
