How i can fix this?
Thanks

Is this a 32Bit or 64Bit DEBIAN linux installation?

Please post also the output of:

uname -m

Hi,
it is 32 bit.
Here is the info:

server:~# uname -m

server:~# uname -a

Thanks for your help.

I have the same problems.
I changed the sources.list from:
"deb http://debian.systs.org/ stable main"
to
"deb http://debian.systs.org/ stable openvz"

Then "apt-get update && apt-get upgrade"

From then on when i do vzctl stop 101
I get this result:

-----------------------

You got these problems first after you changed the sources list to "deb http://debian.systs.org/ stable openvz" and updated the scripts? Before the update the vzctl scripts are working fine?

Me have change the main to openvz because with the main the apt-get update give me errors.
If you check and this page:
http://debian.systs.org/doku.php?id=download
you can see that the right is with openvz

I tested the howto a few days ago with the settings described in the howto and everything worked fine.

Either the guys at debian.systs.org reorganized their pacakges or they uploaded broken packages.

[till]

Update:

It seems that debian.systs.org has updated their packages today. It looks like that the new vzctl scripts needs the latest kernel patch. Please try to recompile your openvz kernel with the latest patch:

http://download.openvz.org/kernel/022stab072.2/patches/patch-022stab072-combined.gz

For me openvz worked very well also for hmm 2 weeks or so.
Now i wanted to "apt-get update && apt-get upgrade" because wel you should do that once a while right :)
There was a sources.list error so i started looking what it was. I needed to change the sources.list just like blueice wrote.
After i updated the sources.list and again run "apt-get update && apt-get upgrade" vzctl got updated and after that the problems started.

so yes, your probably right, they sended broken packages.

Ok, thanks for reporting that. I will try to find out if the packages are broken or if a newer kernel patch is needed and update the howto... :(

How do i recompile the kernel with the latest patch? :o

Cool, thanks.
How do i recompile the kernel with the latest patch? :o

I'am just trying it, maybe it does not help if the packages are really broken. I will post the instructions as soon as i finished my tests.

[till]

The problem is solved now. New packages are available in the debian.systs.org repository. To update your installation, run:

apt-get update
apt-get -u upgrade

Thanks to Thorsten from debian.systs.org for his help and patching the packages so fast!

I've followed the procedure on two systems. Here is what I get on both when I try to start the virtual session:

linus:/vz/template/cache# vzctl start 101

I can SSH into the virtual session but the routing is all screwed up. I can ping other machines on the segment, but it won't route anywhere.

I hope it isn't really obvious so I don't feel stupid, but the solution escapes me. Any suggestions?

Walter

[till]

Do you have an eth0 network card configured? Please post the output of:

ifconfig

[walterharms]

Being the impatient guy I am, I re-installed by test box to check out other projects. I followed my notes to put the OpenVZ back in and this time it worked. Since I'm just cutting and pasting from my notes (a cut down version of what's on line) the only difference I can see is that I may have previously chosen to enter a different domain then the host computer. This time I chose the same domain, and it worked. I can ping external sites. :)

FYI, my ifconfig is

testbox:~# ifconfig

thanks in advance

Make sure 192.168.253.52 isn't already in use by another system.
Did you follow the tutorial as close as possible? Can you rule out that you made types somewhere?

[m_jay]

Hi falko,
of course 192.168.253.52 is free in my entwork
i typed exactly the commands found in the how-to
Can you rule out that you made types somewhere?
i don't understand what you mean (execuse me, i'm not fluent in english) :)

i tried several templates (debian, centos, fedora ..) but i still get the same problem as describe before.
I can give you more details if needed.
Thanks in advance.

i get exactly the same problem in a vmware. But i've already configured one in the same way and it works fine.

The ip 192.168.1.44 is free (i'm sure) .

eth0 is already in use (with the IP address 192.168.1.24)... :confused:

[pmenier]

Yes of course. It's the ip of the "master" .

master => 192.168.1.24

vserver1 => 192.168.1.44

etc...
And i repeat : this config works perfectly on another vmware with the same distrib (debian-3.1 stable).

[pmenier]

Hello,

I've put here http://xoopmenier.dynalias.net/xoops/docext/vservers/details.htm
a config which run perfects.

We see this :
on the master ifconfig outputs :
.....
venet0 Lien encap:UNSPEC HWaddr 00-00-FF-00-00-00-00-00-00-00-00-00-00-00-00-00
....

in the vps ifconfig outputs :
...
venet0 Link encap:UNSPEC HWaddr FF-BF-A8-F6-FF-BF-38-93-00-00-00-00-00-00-00-00
...
venet0:0 Link encap:UNSPEC HWaddr FF-BF-A8-F6-FF-BF-1C-F7-00-00-00-00-00-00-00-00
....

Now on a machine which fails to start the vps :

ifconfig on the master :
...
venet0 Lien encap:UNSPEC HWaddr 00-00-FF-00-00-00-00-00-00-00-00-00-00-00-00-00
....

ifconfig in the vps :
...
venet0 Link encap:UNSPEC HWaddr 00-00-FF-00-00-00-00-00-00-00-00-00-00-00-00-00
....
venet0:0 Link encap:UNSPEC HWaddr 00-00-FF-FF-FF-FF-00-00-00-00-00-00-00-00-00-00
....

We see that HWaddr of venet0 is the same (master/vps) on the broken config. Hope this helps network's gurus to solve our problem...

[pmenier]

Finally i destroy the virtual machine and reinstall it and that works but i didn't like this behavior and i migrate to linux-vserver.

Thanks for your help.
