error id 980
by ozmen62＠hotmail.com
Hi,
First of all, thanks for this great list and the people who try to help eachother.
This time my problem is about engine OVF file or engine storage setting.
How can i came with this idea, because every 2-3 hours engine try to migrate other host(From host1 to host2)
"Invalid status on Data Center B300. Setting status to Non Responsive."
when i check hosts log , see these
ovirt-ha-agent ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine.config.vm ERROR Failed extracting VM OVF from the OVF_STORE volume, falling back to initial vm.conf
ovirt-ha-agent ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine ERROR Engine VM stopped on localhost
ovirt-ha-agent ovirt_hosted_engine_ha.lib.ovf.ovf_store.OVFStore ERROR Unable to extract HEVM OVF
i believe there is some kind of fc storage path or config problem. My storage setting is good. there is no error about them
Is there anyone who experienced about that to solve it
thanks

Cluster level 4.5
by Don Dupuis
What version of libvirt is required for a host to be put in this cluster
level? I am using CentOS 8.3 and cpu is Cascade Lake Server. It says that
my host is only compatible with cluster version 4.2,4.3 and 4.4. I am doing
a new install of Ovirt 4.4.5. I have tried to update libvirt version but
have run into issues. Currently installed libvirt
is libvirt-6.0.0-28.module_el8.3.0+555+a55c8938.x86_64.

How to assign a server disk and nic profile via REST API?
by ovirt.org＠nevim.eu
Hello to everybody,
for about an hour I have stuck my nose in the ovirt and rhev documentation, but I still can't understand how to use the REST API to change the disk profile and nothing the server profile.
Ideally, how to set it for them when setting up a VM.
Thank you so much for the advice.

Slow VM replication
by David Johnson
Hi everyone,
When cloning a VM, I discovered that the time to close appears excessive
based on the underlying platform I am using. It appears that the clone
operation is not making efficient use of the network. I have seen up to 4
GBits sustained throughput by applications on VM's on the cluster.
Is there a configuration I might be missing?
*System specifics:*
Backing store: NFS on TrueNAS running zRaid 3 on 11 spinning disks
Ovirt Controller: I7 desktop
General network: 1 GBit Ethernet
Ovirt Host: Intel(R) Xeon(R) Silver 4216 CPU @ 2.10GHz, 2x32 cores, 256 GB
RAM
Data Network: 10 GBit 10GBase-Twinax, dedicated to this Host and the TrueNAS
*Operation:*
Copying the 60GB partition, the copy operation never exceeds 40 megabytes
per second (less than 0.5 GBit), even though the dedicated 10 Gigabit data
network is not otherwise busy.

Unable to migrate Engine to another HE Host
by Marko Vrgotic
Dear oVirt,
I have already reached out twice regarding the issues that occurred, due to power outage, but noticed only when upgrading engine to latest 4.3. version.
I am unable to redeploy engine on Host2, the hosted-engine file stays empty and VDSM on Hosts1 and 3 is reporting, even though I cleared the metadata for the Host2, on Host 1 and Host3:
2021-04-30 05:57:58,454-0700 ERROR (jsonrpc/7) [ovirt_hosted_engine_ha.client.client.HAClient] Malformed metadata for host 2: received 0 of 512 expected bytes (client:137)
Today I tried to migrate HE from Host 3 to Host 1 and it fails each time with following message:
On Engine:
2021-04-30 12:57:56,961Z ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engine-Thread-1233892) [] EVENT_ID: VM_MIGRATION_TO_SERVER_FAILED(120), Migration failed (VM: HostedEngine, Source: ovirt-sj-03.ictv.com, Destination: ovirt-sj-01.ictv.com).
On source Host:

if ret == -1: raise libvirtError ('virDomainMigrateToURI3() failed', dom=self)
libvirtError: operation aborted: migration out job: canceled by client
I know that this version is end of life – but I would very much appreciate if someone could help me asses if this means corruption in DB or the overall damage, simply to know how to plan further actions.
My impression was that I still had to functional HE Hosts in the pool, but after seeing migration failure, it’s pretty much down to single host.
This is production system, so I cannot just move on to upgrading/deploying to 4.4.
Additionally – :
* Is the effect of the engine-cleanup on HE Host local or it affects all HE Hosts? Could that help bringing the Host back to state so that HE can be re-deployed?
* What is the effect or reinitialize-lockspace?
Kindly awaiting your reply. Happy to provide any additional information needed.

how to override host in console.vv
by Enrico Becchetti
Hi all,
I use ovirt 4.3.10 with an engine running in a standalone virtual machine.
The operating system of this engine and the hypervisors is CentOS 7.
In the initial setup I chose a name for the engine, ovirt.local, then I
added
a second public IP address named ovirt.mydomain in order to allow the
user portal
also from the Internet.
Now here's my problem. Users are able to connect to the VM portal but
they cannot
access the console of their virtual machines.
Checking the console.vv file I noticed that there are two parts, the
first [virt-viewer]
which contains the hypervisor on which the virtual machine runs, and the
second in
this configuration [ovirt] inside ovirt I've got "host = ovirt.local: 443".
Now I would like to change the value of the "host" parameter with the FQDN.
Can you tell me how I can set an override of this variable ?
Thanks a lot.
Best Regards
Enrico
