HostedEngine HA Engine Network Status
by Joseph Goldman
Hi List,
Running a 3 node setup for a client, i'm constantly having the
HostedEngine move itself around, whatever node its on ends up penalizing
its score so low that it forces a migrate to the other node.
Looking at /var/log/ovirt-hosted-engine-ha/agent.log shows a decent
amount of:
MainThread::INFO::2020-05-21
15:47:54,742::states::135::ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine::(score)
Penalizing score by 319 due to network status
What I want to know is how do I get more debug out of this to know
what network status its concerned about, so I can go about stablising it.
The system is heavily monitored with ping checks, never drops link and
never drops ICMP. None of its VM's falter accessing shared NFS space for
disk storage so I'm not sure what the concern is. The node will
literally over time penalise itself down to ~2000 and then HA agent will
want it to swap nodes. It's not necessarily a bad thing but generates a
heap of status emails multiple times a day which is just garbage - and
makes the HE unavailable sometimes when mid-admin task.
Any help is appreciated.
Thanks,
Joe

Are the Host storage requirements changed in oVirt 4.4?
by Stefano Stagnaro
Seems like the new minimum local storage for an Host is now 63 GiB,
compared to the 55 GiB of the 4.3.
If so, the four Installation guides should be updated reflecting the new
value.
Thank you and congratulations for the new release.

You're welcome helping organizing one :-) I would be happy to join!
I wonder how a virtual release party may look like?

oVirt and Fedora
by Sandro Bonazzola
If you have followed the oVirt project for a few releases you already know
oVirt has struggled to keep the pace with the fast innovation cycles Fedora
Project is following.
Back in September 2019 CentOS project launched CentOS Stream as a rolling
preview of future RHEL kernels and features, providing an upstream
development platform for ecosystem developers that sits between Fedora and
RHEL.
Since then the oVirt project tried to keep the software working on Fedora,
CenOS Stream, and RHEL/CentOS but it became quickly evident the project
lacked resources to keep the project running on three platforms. Further,
our user surveys show that oVirt users strongly prefer using oVirt on
CentOS and RHEL.
With the upcoming end of life of Fedora 30 the oVirt project has decided to
stop trying to keep the pace with this amazing platform, focusing on
stabilizing the software codebase on RHEL / CentOS Linux. By focusing our
resources and community efforts on RHEL/CentOS Linux and Centos Stream, we
can provide better support for those platforms and use more time for moving
oVirt forward.

You might want to pass also --he-remove-storage-vm , and perhaps also
--he-remove-hosts . This removes them, obviously, only from the database,
does not connect to them or do anything on them.
You'll then have to add them again. You will not be able to do that if
there are running VMs on them, I think.
So:
If you need to keep the VMs up, and have some of them on the hosted-engine
hosts, do not use these options, but do test very well, and study the bugs
for which these options were added - you can check git log for this file
searching this:
https://github.com/oVirt/ovirt-engine/commits/master?after=3cd2766ae1576b...
https://github.com/oVirt/ovirt-engine/commit/542e4a318584c8601159b4bd6d57...
Bug-Url: https://bugzilla.redhat.com/1240466
Bug-Url: https://bugzilla.redhat.com/1235200
The engine will still think that it's a hosted-engine, so it will likely be
confused. Perhaps --he-remove-storage-vm is enough for that.
This is likely to be problematic, see above bugs.
If you don't need to keep the VMs up, it's probably safer to just take all
of them down, pass also --he-remove-hosts, and then, in the new engine, add
back the hosts. Or even:
Install a new engine, do not restore the backup, add the hosts, and import
the storage domains.

No idea why they are down. Check engine.log. How long did you wait? Did the
engine have access to the hosts? Can you manually ssh to them from the
engine machine?

Host "Unassigned Logical Networks" list is wrong
by Matthias Leopold
Hi,
I'm having a special issue with assigning logical networks to host
interfaces via label.
I'm used to assigning logical networks (tagged VLANs, VM network flag) a
"Network label", which I can choose from a drop down menu in the UI
dialog. These networks are automatically flagged "assign" and "require"
in my cluster and I expect them to be synced to hosts physical interface
to which I "drag and dropped" the label. This always seemed to work and
I never worried.
Now I noticed that when I look at the host "Setup Host Networks" dialog
again, that the last(?) logical networks I provisioned as explained
above show up as "Unassigned Logical Networks" with a mouse over text of
"Network should be assigned to 'foo' via label 'bar'. However for some
reason it isn't". This has to be some presentation error, because the
networks are in fact assigned which is also visible in the hosts
"Network Interfaces" tab.
The "Sync All Network" buttons in "Host" - "Network Interfaces" and
"Cluster" - "Logical Networks" tabs are inactive.
When hosts are put to maintenance and activated again the error disappears.
My oVirt version is 4.3.7.
Cluster switch type is "Linux Bridge".
This may seem a minor error, but since it affects my production clusters
and a couple of VLANs I can't afford to play around with host network
configuration. Can anybody explain this? Any help would be appreciated.
thx
Matthias
