The conclusion is that the backing file stored on NFS that is the same
for all 950 hosts / 10500 guests was deleted and immediatelly raised a
read-only filesystem on the guest, seems that there's no way to avoid
that.
We developed a script to recover from that scenario if the same happens.
Basically doing:
* virsh stop
* qemu-ndb connect
* fsck
* qemu-ndb disconnect
* virsh start
best regards.
