Hi Burkhard,
I seemed to have missed that part but even though allowing
access (rwx) to the cache pool it still has a similar (not same)
problem. The VM process starts but it looks more like a dead or
stuck process trying forever to start and has high CPU (for
the qemu-system-x86 process). When I kill the process, as it
never times out, I get the following error.
internal error: early end of file from monitor: possible

I understand that there is something similar on launchpad and
some replies refer to hammer disabling the feature causing the
error with "lttng-ust-wait-5"
but I still seem to get it.
At least the libvirt user is able to access both pools now.
Can you post the complete configuration for both pool (eg. ceph osd
dump | grep pool)? I remember having some trouble with configuration
cache pools for the first time. You need to set all the relevant
options (target size/objects etc.).
Best regards,
Burkhard
