Hi,

I'am trying to use veth in openvz-2.6.28-53

I did try the following :

vzctl set 167 --netif_add eth0 --save

vzctl start 167 and got :

Starting VE ...
VE is mounted
Setting CPU limit: 100
Setting CPU units: 1000
Configure meminfo: 2147483647
Set hostname: vm167.example.com
File resolv.conf was modified
Configure veth devices: veth167.0
SIOCGIFFLAGS: No such device

In CE0 i have an interface which is named veth167.0_ifren
but no veth167.0 interface

In VE167 I have an eth0 which is up and configured

Ping doesn't work Sad


Any clues ?

Thanks
Eric

Shocked What do you have in mind?
Could you possibly show "ip a l" and "cat /proc/vz/veth" from HN before you've set
"vzctl set 167 --netif_add eth0 --save", then set eth0 inside VE and show "ip a l", "cat /proc/vz/veth" again. And also "vzctl --version" and "uname -a" from HN.

where have you got your kernel? Please, describe what steps have you done to get/build it.

Hello,

just in case (it shouldn't take many time) please download the latest vzctl version from here http://git.openvz.org/, try with it (download via "git clone (http|git)://git.openvz.org/pub/<project name> <destination dir>", ./autogen.sh, ./configure,make then use ./src/vzlist, ./src/vzctl binaries). Try with ./src/vzctl does this error still occur?

Hello,

I didn't try the modified version of vzctl,
but change my kernel to vanilla 2.6.18 + patch-53.1.19.el5.028stab053.14-combined.gz

and the problem was solved

Thanks

Hi,

I wasn't be able to reproduce this issue Sad
could you possibly looak at this file - "drivers/net/veth.c" on both your kernels. Is there any difference? Could you possibly attach both of them?
