VM hangs after migration
by Giorgio Biacchi
Hi,
I have a fresh Ovirt installation (4.4.10.7-1.el8 engine and oVirt Node
4.4.10) on a Dell VRTX chassis. There are 3 blades, two of them are
identical hardware (PowerEdge M630) and the third is a little newer
(PowerEdge M640). The third has different CPUs, more RAM, and slower
NICs. I also have a bunch of data domains some on the shared PERC
internal storage and others on an external iSCSI storage, all seems
configured correctly and all the hosts are operational.
I can migrate a VM back and forth from the first two blades without any
problem, I can migrate a VM to the third blade but when I migrate a VM
from the third blade to any of the other two the task terminate
successfully, the VM is marked as up on the target host but the VM
hangs, the console is frozen and the VM stops to respond to ping.
I have no clues about why this is happening and I'm looking for
suggestions about how to debug and hopefully fix this issue.
Thanks in advance

Cannot log into oVirt Manager - certificate issue
by Diggy Mc
I cannot log into oVirt Manager. My browser gave me a warning that the site's certificate has expired. Then when I try to log in, I receive the following error message:
"PKIX path validation failed: java.security.cert.CertPathValidatorException: validity check failed"
How can I fix this problem? In advance, thank you for your help.

can't use vmconsole anymore
by Nathanaël Blanchet
Hi,
I was used to use the vmconsole proxy, but since a while, I'm getting
this issue (currently 4.4.5):
# ssh -t -p 2222 ovirt-vmconsole(a)air.v100.abes.fr connect
ovirt-vmconsole(a)air.v100.abes.fr: Permission denied (publickey).
I found following in the engine.log
2021-04-15 17:55:43,094+02 ERROR
[org.ovirt.engine.core.services.VMConsoleProxyServlet] (default task-4)

The user key is the good one, I use the same with my other engines and I
can successfully connect to vm consoles.
Thank you for helping

VM HostedEngine is down with error
by souvaliotimaria@mail.com
Hello everyone,
I have a replica 2 + arbiter installation and this morning the Hosted Engine gave the following error on the UI and resumed on a different node (node3) than the one it was originally running(node1). (The original node has more memory than the one it ended up, but it had a better memory usage percentage at the time). Also, the only way I discovered the migration had happened and there was an Error in Events, was because I logged in the web interface of ovirt for a routine inspection. Βesides that, everything was working properly and still is.
The error that popped is the following:
VM HostedEngine is down with error. Exit message: internal error: qemu unexpectedly closed the monitor:
2020-09-01T06:49:20.749126Z qemu-kvm: warning: All CPU(s) up to maxcpus should be described in NUMA config, ability to start up with partial NUMA mappings is obsoleted and will be removed in future
2020-09-01T06:49:20.927274Z qemu-kvm: -device virtio-blk-pci,iothread=iothread1,scsi=off,bus=pci.0,addr=0x7,drive=drive-ua-d5de54b6-9f8e-4fba-819b-ebf6780757d2,id=ua-d5de54b6-9f8e-4fba-819b-ebf6780757d2,bootindex=1,write-cache=on: Failed to get "write" lock
Is another process using the image?.
Which from what I could gather concerns the following snippet from the HostedEngine.xml and it's the virtio disk of the Hosted Engine:
<disk type='file' device='disk' snapshot='no'>
<driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads' iothread='1'/>
<source file='/var/run/vdsm/storage/80f6e393-9718-4738-a14a-64cf43c3d8c2/d5de54b6-9f8e-4fba-819b-ebf6780757d2/a48555f4-be23-4467-8a54-400ae7baf9d7'>
<seclabel model='dac' relabel='no'/>
</source>
<target dev='vda' bus='virtio'/>
<serial>d5de54b6-9f8e-4fba-819b-ebf6780757d2</serial>
<alias name='ua-d5de54b6-9f8e-4fba-819b-ebf6780757d2'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/>
</disk>
I've tried looking into the logs and the sar command but I couldn't find anything to relate with the above errors and determining the reason for it to happen. Is this a Gluster or a QEMU problem?
The Hosted Engine was manually migrated five days before on node1.
Is there a standard practice I could follow to determine what happened and secure my system?
Thank you very much for your time,
Maria Souvalioti

Hi all.
Is it possible to configure oVirt for work with two NICs in bond/LACP
across two switches, according to the image below?

Thank you all.
You guys do a wonderful job.

OVS switch type for hosted-engine
by Devin A. Bougie
Is it possible to setup a hosted engine using the OVS switch type instead of Legacy? If it's not possible to start out as OVS, instructions for switching from Legacy to OVS after the fact would be greatly appreciated.
Many thanks,
Devin

USB3 redirection
by Rik Theys
Hi,
I'm trying to assign a USB3 controller to a CentOS 7.4 VM in oVirt 4.1
with USB redirection enabled.
I've created the following file in /etc/ovirt-engine/osinfo.conf.d:
01-usb.properties with content
os.other.devices.usb.controller.value = nec-xhci
and have restarted ovirt-engine.
If I disable USB-support in the web interface for the VM, the xhci
controller is added to the VM (I can see it in the qemu-kvm
commandline), but usb redirection is not available.
If I enable USB-support in the UI, no xhci controller is added (only 4
uhci controllers).
Is there a way to make the controllers for usb redirection xhci controllers?
Regards,
Rik
