Dear 

is it possible to point LXC container to a virtual interface ?
I have only one interface 'eth1' and i would like LXC containers using
"Virtual Interfaces" 
When running the LXC container the network card disapears and server
network is down.
I need to reboot the computer in order to retreive the eth1 main
interface.

I have these IP settings :
eth1      Link encap:Ethernet  HWaddr 00:0C:29:AD:40:A7  
          inet adr:192.168.1.64  Bcast:192.168.1.255

And this configuration file.

lxc.utsname =vps-1
lxc.tty = 4
lxc.pts = 1024
lxc.network.type = phys
lxc.network.flags = up
lxc.network.link = eth1:3
lxc.network.name = eth0
lxc.network.flags = up
lxc.rootfs = /home/vps-servers/vps-1/rootfs
lxc.cgroup.devices.deny = a
lxc.cgroup.devices.allow = c 1:3 rwm
lxc.cgroup.devices.allow = c 1:5 rwm
lxc.cgroup.devices.allow = c 5:1 rwm
lxc.cgroup.devices.allow = c 5:0 rwm
lxc.cgroup.devices.allow = c 4:0 rwm
lxc.cgroup.devices.allow = c 4:1 rwm
