Unable to create guest VM using virt-install

[Namu]

Working in Ubuntu 14.04 (Trusty Tahr), running libvirt version 1.2.1.

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

Starting install...
ERROR Connection is closed
Domain installation does not appear to have been successful.
If it was, you can restart your domain by running:
  virsh --connect qemu:///system start nam
otherwise, please restart your installation.
root@srvr-931:~# virsh --connect qemu:///system start nam
error: failed to get domain 'nam'
error: Domain not found: no domain with matching name 'nam'

I see this in virt-install.log -

I run the same command on Ubuntu 12.04.1 LTS and I don't see any problem there. This looks very similar to Bug#1180281, but I don't see a solution there. Does anyone know if this is fixed now? And the versions that I need to use?

Thank you!

You did not include "--connect lxc:///" in your command, so virsh connected to the qemu driver.

Please see
https://www.berrange.com/posts/2013/08/12/running-a-full-fedora-os-inside-a-libvirt-lxc-guest/
for an example of how to use virt-install with livirt-lxc.

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

Hm, sorry! I thought the subject of the bug said lxc. In that case, confirmed.

Hi,

can you still reproduce this bug?
