[Qemu-discuss] VM hang for unknown reason

Hi,
  I have a setup of 7 ceph servers running version 10.2.10 on 10G links
and I have 17 hypervisors 10G links, 32 cores/HT each with 512G of ram
running libvirt 4.0.0 and qemu-kvm 2.9.0. I'm running just over 1000 VM
on those 17 hypervisors. The issue is that from time to time, and
especially when creating new VM there are other VM hanging randomly
forever. I have to destroy and restart them once the VM freezes. The
qemu process is still running, but I have no logs at all. I looked for
libvirt/qemu/ceph and OS logs... dmesg show nothing. On the ceph size I
don't see errors either.

This Only thin I can see is the following using strace on the qemu-kvm
process. (see at the bottom of this message)
The more VM I have the more chances of having VM freezing increases.

Any idea how to troubleshoot this and find the source of the issue?
I kept one hanged VM for investigation.
Thank you.
