Comment 3 for bug 1301598

I'm confused by your comment.

Why do I need to "--connect lxc:///" to connect to qemu driver?

Why do I not need this in Ubuntu 12.04.1 LTS?

I can run this command: "virt-install --name nam --ram 4096 --disk path=/var/lib/libvirt/images/nam.img,bus=virtio --import --noautoconsole --network network:default,model=virtio" in Ubuntu 12.04 and create a VM.

I don't get how this is related to LXC!

Per your comment, I did try the following -

root@srvr-931:~# virt-install --connect lxc:/// --name nam --ram 4096 --disk path=/var/lib/libvirt/images/nam.img,bus=virtio --noautoconsole --network network:default,model=virtio --force

Starting install...

Domain creation completed. You can restart your domain by running:
  virsh --connect lxc:/// start nam

root@srvr-931:~# virsh --connect lxc:/// start nam
error: Domain is already active

root@srvr-931:~# virsh list --all
