what happens to vms when a host shutdowns?
by Nathanaël Blanchet
Hi,
We are installing UPS powerchute client on hypervisors.
What is the default vms behaviour of running vms when an hypervisor is
ordered to shutdown: do the vms live migrate or do they shutdown
properly (even the restart on an other host because of HA) ?

[4.4.7] The latest guest agent needs to be installed and running on the guest
by Christoph Timm
Hi list,
I have upgraded my oVirt from 4.4.4 to 4.4.7 and notice that some VMs
have issues to report the performance information via the guest agent.
I see the following message on the VMs: The latest guest agent needs to
be installed and running on the guest
The qemu-guest agent is installed on VMs (the VM OS is CentOS 8).
Any advice how to troubleshoot this?
I can see the stats will be presented in the GUI, if I migrate the VM to
a different host.
Best regards
Christoph

I can login just fine to the VM over SSH but when I try to login over
the web interface as admin, the password is not accepted. I tried both
complex and simple passwords for root/admin but none worked so far.
This previous discussion did not solve my problems:

Snapshot not working
by Facundo Badaracco
hi everyone,
I have a glusterFS replica x3 node.
I can't create snapshot. when I create it, if I select to save the memory,
then in the disks section only appears the snapshot of the memory and in
locked state. If instead, I remove the option to make snapshot of the
memory, it does not make the snapshot saying "failed".
Any idea?

Yes. It is what I configured during the setup, and which I use when I ssh from the host to the engine VM.
Sorry, I should have mentioned this in my previous message.

oVirt 4.5.2 /var growing rapidly due to ovirt_engine_history db
by sohail_akhter3＠hotmail.com
Hi,
We have recently upgrade our oVirt environment to 4.5.2 version. Environment is based on hosted-engine. Since we have upgrade we noticed rapid incrase in /var partition in engine VM. It is increasing very rapidly. If we vacuum ovirt_engine_history db, /var size reduces but next day size will increase again upto 5-10%. We did db vacuuming couple of time but not sure we it is increasing so rapidly.
Here is the partial output of vacuuming that was done on 26-08-22. Table "host_interface_hourly_history" had more entries to be removed. Rest of the table had not much entries. Previously table "host_interface_samples_history" had entries to be removed.
Any Idea what can be the reason for that?
# dwh-vacuum -f -v
SELECT pg_catalog.set_config('search_path', '', false);
vacuumdb: vacuuming database "ovirt_engine_history"
RESET search_path;
SELECT c.relname, ns.nspname FROM pg_catalog.pg_class c
JOIN pg_catalog.pg_namespace ns ON c.relnamespace OPERATOR(pg_catalog.=) ns.oid
LEFT JOIN pg_catalog.pg_class t ON c.reltoastrelid OPERATOR(pg_catalog.=) t.oid
WHERE c.relkind OPERATOR(pg_catalog.=) ANY (array['r', 'm'])
ORDER BY c.relpages DESC;
SELECT pg_catalog.set_config('search_path', '', false);
VACUUM (FULL, VERBOSE) public.host_interface_samples_history;
