Hi,
It happend to me in case of a server. Investigating I found out that
libvirt-bin isn't starting fast enough for nova-compute. So I added this line
in /etc/init/nova-compute.conf "start libvirt-bin" to look as:
pre-start script
mkdir -p /var/run/nova
chown nova:root /var/run/nova/
mkdir -p /var/lock/nova
chown nova:root /var/lock/nova/
modprobe nbd
start libvirt-bin
end script
Regards,
Gabriel

Hello, i've installed openstack following the ubuntu 12.04 deploy guide, only
problem is that nova-compute has to be started manually, by default it doesn't
start on boot, this is the error log:

Then after system boot a start nova-compute make everything working.
Any idea?
