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 problem:

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
