Hello all,

I am trying to work with OpenStack(Kilo) and have created a small setup with 1 Controller, 1 neutron, 1 compute (physical host) and 1 swift. All other machines except compute are QEMU VMs.

Followed the installation guide with few issues being faced. But unable to get over this one on my own.

It happened yesterday and since then I am unable to start nova-compute service.

In nova-compute.log on compute node I am getting this:

Check if libvirtd.service running?

# systemctl status libvirtd.service

Hi.. Actually I tried that too. It is running fine.

Nothing worked. At last, I had to reinstall compute service. Surprisingly, it worked this time around. I don't know why I got this error previously.
