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

VM Disk extend not reflected in VM oS
by simon＠justconnect.ie
Hi All,
I extended a VM disk via oVirt Manager (4.4.8) without error, but when I checked the VM (fdisk & lsblk) the size has not changed.
Any help as always would be appreciated.

Yes. It is what I configured during the setup, and which I use when I ssh from the host to the engine VM.

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);

Notified that Engine's certification is about to expire but no documentation to renew it
by Guillaume Pavese
Hello
We are receiving the following notifications from our ovirt manager :
Message:Engine's certification is about to expire at 2022-05-03. Please
renew the engine's certification.
Severity:WARNING
Effectively :
# openssl x509 -in /etc/pki/ovirt-engine/certs/engine.cer -startdate
-enddate -noout
notBefore=Mar 30 04:48:15 2021 GMT
notAfter=May 3 04:48:15 2022 GMT
However I can not find any documentation on how to renew this certificate.
The following doc only convers changing apache-ca.pem & apache.cer, and
not engine.cer
Doc oVirt :
https://ovirt.org/documentation/administration_guide/index.html#Replacing...
Doc RHV :
https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.4/...
Any help ?

Certificate expiration
by Joseph Gelinas
Hi,
The certificates on our oVirt stack recently expired, while all the VMs are still up, I can't put the cluster into global maintenance via ovirt-engine, or do anything via ovirt-engine for that matter. Just get event logs about cert validity.
VDSM ovirt-1.xxxxx.com command Get Host Capabilities failed: PKIX path validation failed: java.security.cert.CertPathValidatorException: validity check failed
VDSM ovirt-2.xxxxx.com command Get Host Capabilities failed: PKIX path validation failed: java.security.cert.CertPathValidatorException: validity check failed
VDSM ovirt-3.xxxxx.com command Get Host Capabilities failed: PKIX path validation failed: java.security.cert.CertPathValidatorException: validity check failed
Under Compute -> Hosts, all are status Unassigned. Default data center is status Non Responsive.
I have tried a couple of solutions to regenerate the certificates without much luck and have copied the originals back in place.
https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.3/...
https://access.redhat.com/solutions/2409751
I have seen things saying running engine-setup will generate new certs, however engine doesn't think the cluster is in global maintenance so won't run that, I believe I can get around the check with `engine-setup --otopi-environment=OVESETUP_CONFIG/continueSetupOnHEVM=bool:True` but is that the right thing to do? Will it deploy the certs on to the hosts as well so things communicate properly? Looks like one is supposed to put a node into maintenance and reenroll it after doing the engine-setup, but will it even be able to put the nodes into maintenance given I can't do anything with them now?
Appreciate any ideas.

Re: Should I migrate existing oVirt Engine, or deploy new?
by David White
Hi Paul,
Thanks for the response.
I think you're suggesting that I take a hybrid approach, and do a restore of the current Engine onto the new VM. I hadn't thought about this option.
Essentially what I was considering was either:
- Export to OVA or something
OR
- Build a completely new oVirt engine with a completely new domain, etc... and try to live migrate the VMs from the old engine to the new engine.
Do I understand you correctly that you're suggesting I install the OS onto a new VM, and try to do a restore of the oVirt settings onto the new VM (after I put the cluster into Global maintenance mode and shutdown the old oVirt)?

Or would it be better for me to install a completely new Engine, and then somehow migrate all of the VMs from the old engine into the new engine?
