Hello,
we run ovirt 3.2.1 (or 2). I upgraded to RC1, everything was great
(except SPICE. VNC and creating new WM due to serialization bug.).
Because those bugs were irritating, we switched to nightly. Still works
fine (but bug with VMs is not fixed there), than I installed new ovirt
engine management server in KVM virtualization (using libvirtd) due to
taking snapshots before deploying nightly builds. New virtualized engine
works great and I delete old one. Next day I came to work and engine web
page was very very slow, every operation takes ages, that time I found
there were no VMs, no HDDs and so. I converted its qcow2 image to raw,
because I think it has slow DB because of running i qcow2. Did not
helped, than I take a look in nodes logs and found this problem, which I
posted in first email (VMs still running, but not visible in engine VMs
tab, but on host I can see number of running VMs). After restart bug
disappeared, but VMs too.
Today I reinstalled engine with oVirt 3.3.0rc1. But all my VMs are gone.
Even from storage. (but disappearing from storage may be my fault during
recovery).
I can provide logs from both two nodes and (hopefully) from engine too.
I can provide you with those logs, but not publicly. Sorry.
Thank you,
Jakub Bittner, NSA Czech
