This doesn't seem to be a generic problem so I'm downgrading the
severity. I'm not seeing this here. Please add the domain logs,
hypervisor URI, VM configuration and debugging output (using
LIBVIRT_DEBUG=1). 
Judging from the error message cgoups are not working correctly for you.
Libvirt tries to detect this on startup, why this failed should be in
the logs.
Cheers,
