You should have seen at 'sudo virsh list --all', plus looking at
/etc/libvirt/qemu/*.xml to check how many instances were defined.<br>
I do suspect also that for some reason (probably nova-compute down),
a clean-up of 00002c probably didn't work. Anyway, this is fixed as
you mention.<br>

The DHCP reply is correctly received by the instance from the
network node to the compute node. This is not a network issue (at
least for IP assignation).<br>
I would be more concerned about the SIOCDELRT error above. Do you
try to manually remove a network route at bootup ? Seems like the
'route del' is failing because the route is not already existing.<br>
<br>
<br>
As already said, you absolutely need VNC support for investigating.
Could you please fix your VNC setup which is incorrect ?<br>

Try in nova-compute.conf :<br>
vncserver_proxyclient_address=<compute node mgmt IP><br>
vncserver_listen=<compute node mgmt IP><br>
and in nova.conf :<br>
novncproxy_base_url=<a class="moz-txt-link-freetext" href="http://">http://</a><controler node mgmt
IP>:6080/vnc_auto.html<br>
<br>
and restart nova-compute. <br>

Sounds like your virtual device is not created.
Could you please launch a new VM and paste
/var/log/nova/nova-compute.log ?<br>
