Re: [libvirt] Bringing up LXC container from virsh command prompt.



So, again I need to add one network interface in the libvirt XML?. It
will not take the interface which was created earlier while creating
container using lxc-tools?.
But, in the container which was created with lxc-tools(lxc-create,
lxc-start ..etc), I am not getting any such issues. 
Why I am getting these issues in virsh command prompt, when I am
mounting the same rootfs that was used while creating container using
lxc-tools.
Please clarify.

Regards,
Srikanth.

You've not listed any network interface here. So the container is
inheriting the host network. If you add a network interface it'll work
as you expect
