Re: Constantly XFS in memory corruption inside VMs
by Strahil Nikolov
Damn...
You are using EFI boot. Does this happen only to EFI machines ?
Did you notice if only EL 8 is affected ?

Can you check the output on the VM that was affected:
# cat /etc/*release
# sysctl -a | grep dirty

Hi Strahil.
I’m not using barrier options on mount. It’s the default settings from CentOS install.
I have some additional findings, there’s a big number of discarded packages on the switch on the hypervisor interfaces.
Discards are OK as far as I know, I hope TCP handles this and do the proper retransmissions, but I ask if this may be related or not. Our storage is over NFS. My general expertise is with iSCSI and I’ve never seen this kind of issue with iSCSI, not that I’m aware of.
In other clusters, I’ve seen a high number of discards with iSCSI on XenServer 7.2 but there’s no corruption on the VMs there...
Thanks,

I've cases where the VM was new, just installed, run dnf -y update to get the updated packages, rebooted, and boom XFS corruption. So perhaps the motion process isn't the one to blame.

Sometimes the corrupted data are “all zeroes”, sometimes there’s data there.

No errors logged on dmesg, nothing on /var/log/messages and no errors on the “zpools”, not even after scrub operations. On the switch, a Catalyst 2960X, we’ve been monitoring it and all it’s interfaces. There are no “up and down” and zero errors on all interfaces (we have a 4x Port LACP on the TrueNAS side and 2x Port LACP on each hosts), everything seems to be fine. The only metric that I was unable to get is “dropped packages”, but I’m don’t know if this can be an issue or not.

Unable to live migrate a VM from 4.4.2 to 4.4.3 CentOS Linux host
by Gianluca Cecchi
Hello,
I was able to update an external CentOS Linux 8.2 standalone engine from
4.4.2 to 4.4.3 (see dedicated thread).
Then I was able to put into maintenance one 4.4.2 host (CentOS Linux 8.2
based, not ovirt node ng) and run:
[root@ov301 ~]# dnf update
Last metadata expiration check: 0:27:11 ago on Wed 11 Nov 2020 08:48:04 PM

(btw: there is no other active host; there is a ov300 host that is in

No available host was found to migrate VM c8client to.
It seems the root error in engine.log is:

It seems that during the host update the OVN configuration has not been
maintained.
Right now all my active VMs are with at least a vnic on OVN so I cannot
test the scenario of migrating a VM without OVN based vnic.
In fact on engine I see only the currently active host in 4.4.2 (ov200) and
another host that is in maintenance (it is still in 4.3.10; I wanted to
update to 4.4.2 but I realized that 4.4.3 has been out...):

Any hint about the reason of losing OVN config for ov301 and the correct
procedure to get it again and persiste future updates?
NOTE: this was a cluster in 4.3.10 and I updated it to 4.4.2 and I noticed
that the OVN config was not retained and I had to run on hosts:
[root@ov200 ~]# vdsm-tool ovn-config engine_ip ov200_ip_on_mgmt
Using default PKI files
Created symlink
/etc/systemd/system/multi-user.target.wants/openvswitch.service →
/usr/lib/systemd/system/openvswitch.service.
Created symlink
/etc/systemd/system/multi-user.target.wants/ovn-controller.service →
/usr/lib/systemd/system/ovn-controller.service.
[root@ov200 ~]#
Now it seems the problem persists...
Why do I have to run each time?

oVirt 4.4: Self-hosted engine deployment fails with backup restore from 4.3 engine
by Oliver Leinfelder
Hi there,
I'm a bit puzzled about an possible upgrade paths from a 4.3 cluster to
version 4.4 in a self-hosted engine environment.
My idea was:
Set up a new host with a clean ovirt node 4.4 installation, then deploy the
hosted engine on this with a restored backup from the production cluster
and go from there.
This however fails with the following error:
2020-05-27 00:17:08,886+0200 DEBUG

Is this approach (restoring from 4.3) generally supposed to work? If not,
what is the appropriate upgrade path?
Thank you!

ovirt 4.3 - locked image vm - unable to remove a failed deploy of a guest dom
by 3c.monitor＠gruppofilippetti.it
Hi all.
I've deployed a VM from a corrupted template (it's disk is missing, but I've checked it later...).
My Software Version is:4.3
Now, I have an unmanaged VM in inventory and unable to remove it too.
It's reference is "locked image".
I've restarted ovirt-engine many times on self-hosted engine and hosts too, but no benefits.
So, what's now?
I've also consulted: https://access.redhat.com/solutions/396753
but still no results.
No tasks or items results to be "locked"...
Any other ideas?
Thanks a lot.

How to install win-virtio Drivers (aka guest tools) silently
by t.hofmann＠klett-it.net
Hi,
i am currently trying to automate an upgrade process from the "old" oVirt 4.3 Guest Tools new one which should using starting with oVirt 4.4
To achieve this I have to install the win-virtio tools quietly. This works even if I use the parameters /install /passive /norestart. But then the oVirt Guest Agent is not installed. Is there a parameter or another way to install it during a silent installation?
Thanks in advance.

Cannot SSH into the self hosted host (going through tutorial)
by jenia.ivlev＠gmail.com
Hello.
I want to install oVirt on my PC and for this purpose I'm following the tutorial which instructed me to make a VM and install there the oVirt self hosted host: https://www.ovirt.org/documentation/installing_ovirt_as_a_self-hosted_eng...
I cannot SSH to this new oVirt install - I get the error "Connection refused" (Even though I see something listening on port 22 by running `netstat -an`). So I tried stopping `sshd`and I got the same error. Tried to do all of this with `telnet 192.168.122.1 22`, I get the same error "Connection refused".
Also, Yum returns "could not resolve host: https://mirrors.fedoraproject.org"
I can ping the machine though from my PC.
I turned off `firewalld`. `iproute -S` returns `ACCEPT` for everything.
My PC is running archlinux and I installed the new VM using "Virtual Machine Manager". Normally, I can easily SSH to any VM I create. Maybe someone know what I'm doing wrong?
Thanks kindly
Jenia
P.S.
Running `nodectl check` returns "ok" for all.
