Public bug reported:
Seeing libvirt error while trying to deploy instances in OpenStack
deployment:
"error: internal error: Unable to find 'cpuacct' cgroups controller mount".
This is recreatable for kilo and liberty.
The cloud version for kilo is root@lambert:~# dpkg -l|grep virt
ii libvirt-bin 1.2.12-0ubuntu14.2~cloud0
amd64 programs f
or the libvirt library
ii libvirt0 1.2.12-0ubuntu14.2~cloud0
amd64 library fo
r interfacing with different virtualization systems
And I was also able to recreate with liberty version:
root@lambert:/etc/apt/sources.list.d# apt-cache policy libvirt-bin
libvirt-bin:
Installed: 1.2.16-2ubuntu11~cloud0
Candidate: 1.2.16-2ubuntu11~cloud0

When I tried on a system with 1.2.2-0ubuntu13.1.7, there was no issue starting
the container.
If this is an issue with the version in the cloud archives, when was it
fixed and when does the fix makes it to the kilo and liberty cloud
archives?
Below is the error on the nova-compute node with actual instance xml and
I also recreated with a basic container:
