How to add second venet interface to openvz guest, or change.

[timucin]

I've setup a proxmox server with one ethernet and created the guests.

After a while, I've installed a second nic into the computer and now my openvz guest (linux, ubuntu server edition 10.04) runs with the virtual ethernet (venet) running on the first nic. I want to change it to run on the second nic but I'm at a loss how to do that.

My network subnets are:
192.168.2.0/24 and 10.0.100.0/24
My guest linux server runs on the 192.168.2.0/24 subnet with ip 192.168.2.11 but I want it to be reached on the other subnet with ip 10.0.100.11.

and, another related question: is it possible to add second virtual venet nic to openvz guest so I can run the guest server on both subnets?

Hi,
of couse you can do that. Edit the config-file (in /etc/vz/conf) like this:

NETIF="ifname=eth0,bridge=vmbr0,mac=CA:E3:43:25:79:66,host_ifname=veth104.0,host_mac=00:18:51:C5:C9:22;ifname=eth1,bridge=vmbr10,mac=CA:E3:43:25:79:55,host_ifname=veth104.1,host_mac=00:18:51:C5:C9:11"

thanks udo,

But, the solution you have given works for veth interfaces, I'm using venet in my guest machine so I need solution for venet interface.
