Re: VM frozen during snapshot removing
by Domen Cesnik
Hi,
This looks like a bug.
We had a same issue with few VMs
After Veeam support was involved they redirected us to Oracle as we use
OLVM.
There was in logs

THe same error was with Vinchin.

oVirt networks
by Enrico Becchetti
Dear all,
Ineed your help to understand how to configure the network of a new
oVirt cluster.
Mynew system will have a 4.3 engine thatruns in a virtual machine, andsome
Dell R7525 AMD EPYC hypervisors, eachholding two 4-port PCI network cards.
These servers will have node-ovirt image again in version 4.3.
As for the network, there are two HPE Aruba 2540G, non-stackable, with
24 1Gbs ports
and 2 10Gbs uplinks to the star center.
This is a simplified scheme:
My goal is to make the most of the server's 8 ethernet interfaces to have
both reliability and maximum possible throughput.
This cluster will have two virtual networks, one forovirt management and
one for
the traffic of individual virtual machines.
With that said here's what my idea is. I would like to have two links
aggregated by 4Gbs,
one for ovrtmgt and the other for vmnet.
With the ovirt web interface I can createan active-passive "Mode 1"
bond, but this
won'tallow me to go beyond 1Gbs. Alternatively I could create a "Mode 4"
bond
802.3ad but unfortunately the switches are not stacked and therefore not
even
this solution applies.
This is an example with active passive configuration:
Can you tell me if ovirt can generate//nested bonds? Or do you have
other solutions ?
Thanks a lot !
Best Regards
Enrico

boot from cdrom & error code 0005
by edp＠maddalena.it
Hi.
I have created a new storage domain (data domain, storage type nfs) to use it to upload iso images.
I have so uploaded a new iso and then attach the iso to a new vm.
But when I try to boot the vm I obtain this error:
booting from dvd/cd...
boot failed: could not read from cdrom (code 0005)
no bootable device
The iso file has been uploaded with success in the data storage domain and so the vm lets my attach the iso to the vm in the boot settings.
Can you help me?
Thank you

Re: How to switch oVirt from Cockpit from RHEL9?
by Ruber van der Linden
Cockpit is a control panel for server management. The virtualization is only a part of it.
You can have both Cockpit and oVirt installed on the same server, as they serve for different purposes.
If you already use KVM and have any VM running, installing oVirt over it may cause some trouble. I suggest starting with a clean server using the self hosted engine.

Best way to shutdown ovirt-engine.
by 1990w＠naver.com
Hi all,
Ovirt-engine was configured as vm.
There is a problem because Ovirt-engine's resources are too small.
So I'm going to add resources after I shutdown Ovirt-engine.
What is the best way to shut down Ovirt-engine?
Is it okay to stop engine service and shutdown vm?

VM frozen during snapshot removing
by Kalil de A. Carvalho
Hello all.
In my company we have a oVirt 4.5.4-1.el9 running and a Vinchin Backup &
Recovery 8.0 as a backup solution.
A strange situation. Same VM's stopping working, frozen, when the
snaphost it is been removing. And when this happened we must kill the
process directly in the host because we can't do this on oVirt web
management.
I just found some information on message log, notting on vdsm or libvirt
logs. Here what is in the message log:
Aug 13 21:49:26 HOST libvirtd[5304]: Cannot start job (modify, none, none)
in API remoteDispatchDomainSetSchedulerParameters for domain VM; current
job is (query, none, none) owned by (5332
remoteDispatchConnectGetAllDomainStats, 0 <null>, 0 <null> (flags=0x0)) for
(45s, 0s, 0s)
Aug 13 21:49:56 HOST libvirtd[5304]: Cannot start job (modify, none, none)
in API remoteDispatchDomainSetSchedulerParameters for domain VM; current
job is (query, none, none) owned by (5332
remoteDispatchConnectGetAllDomainStats, 0 <null>, 0 <null> (flags=0x0)) for
(75s, 0s, 0s)
Has anyone passed for this situation?
Bast regards.

moving VMs from old oVirt to new
by Diggy Mc
Since export domains have been deprecated starting with oVirt v4.4, what is the preferred/best method for moving VMs from an old oVirt environment into a new oVirt environment? The two environments are totally independent of each other and therefore need an intermediary.

VM start order
by Sergei Panchenko
Good morning!
Is there any way to configure VM start order? For example, I would like to make it so VM3 starts only after VM2 starts and VM2 starts only after VM1 starts. I know about run/migrate priority, but it is the other scenario.
