OpenVZ for debian how-to problem

Hi falko,
of course 192.168.253.52 is free in my entwork
i typed exactly the commands found in the how-to

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.

 

Hello,
i tried the command

but nothing append when i do this !

Do i need a special configuration on the machine specified as "name server" during the configuration ? Bind, Windows AD or anything else ?

Thanks in advance for your help

 

Are you absolutely sure that 192.168.253.52 isn't already in use?

 

yes, it is 100% sure
that's why this problem looks strange to me

 

What's the output of

Code:

ifconfig

on the main machine? What's the output of

Code:

ping -c4 192.168.253.52

on the main machine?

This means that 192.168.253.52 is already in use in your network.

 

OpenVZ Pb (vmware)

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

arpsend: can't get iface 'eth0:' address : Cannot assign requested address
vps-net_add WARNING: arpsend -c 1 -w 1 -D -e 192.168.1.44 eth0: FAILED
etc....

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

The command arpsend -c 1 -w 1 -D -e 192.168.1.44 eth0 return no errors.

Patrick

 

What's the output of

Code:

ping -c4 192.168.1.44

?

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

 

Re

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).

 

Sample config ok/nok

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...

 

Partially solved

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.
