Nova-Compute-kvm fails in ubuntu server 13.04

[Msekni]

So I have installed the latest ubuntu server 13.04 where KVM package has been replaced by qemu-system-x86.
When i install nova-compute-kvm, it doesn't start because there is no connection to libvirt ! I have tried to used nova-compute-qemu instead of nova-compute-kvm but the problem still persists (see Log below)

My processor supports virtualisation and i used to create VMs normally when i had Folsom. After updating ubuntu server 12.10 to ubuntu 13.04, it seems that things changed and communication to libvirt is lost. This is the nova-compute.log :

I had the same issue too. I resolved it by doing the following:

apt-get purge libvirt-bin pm-utils
apt-get install -y kvm libvirt-bin pm-utils
service libvirt-bin restart
apt-get install nova-network nova-api-metadata nova-compute-kvm
cd /etc/init.d/; for i in $(ls nova-*); do sudo service $i restart; don

Looks like an Ubuntu packaging upgrade issue -- please reopen upstream task if you can point to an upstream bug

[davisvictor (dvsvictor)]

I have the same problem.

I am using your step-by-step, Msekni.
