Import machines
by Demeter Tibor
Dear Listmembers,
Is it possible to import ovirt 4.3's VMs into a new ovirt environment via our old storage domains?
I have an old 4.3 self-hosted system with 3 storage domain, but it seems very difficult upgrade until 4.5.
I just wondering, what if I do install a complety new system and just attach the old storge domains to that.
Is it will work ? If yes, what will do it with our VM-s and networks.
Thanks in advance,
Regards.

Veeam Backup for RHV (oVirt)
by markeczzz＠gmail.com
Hi!
Not really sure if this is right place to ask, but..
I am trying to use Veeam Backup for Red Hat Virtualization on oVirt 4.5.1.
I have been using it on version 4.4.10.7 and it works ok there.
On Veeam Release page it says that supported OS is RHV 4.4SP1 (oVirt 4.5).
When i try to do backup, this is what i get from Veeam backup.
No errors in vdsm.log and engine.log..

Are there any changes between version 4.5 and 4.5.1 that are preventing using this?
Any solution?

oVirt 4.2 host cert expired
by Don Dupuis
Hello
I have an environment with quite a lot of hosts using local storage
domains. The engine and hosts cert expired. I ran engine-setup on the
ovirt-engine so that the engine cert would get updated and then followed
this https://access.redhat.com/solutions/3532921 to manually update the
hosts certs so that hopefully the engine can talk to vdsm and then carry
out the cert enrollment process, but no luck. I am getting is error in
vdsm.log:
2022-07-26 18:32:12,743-0500 INFO (Reactor thread)

Capabilities failed: General SSLEngine problem
I substituted host01 for the real FQDN for this post.
I can't get the hosts in a mode so that I can put it in maintenance mode
and I also want to be carefull about reinstalling because the vms are
stored on local storage domain on host. Fingerprints match on the certs and
when I sign the vdsmcert on the engine and then copy back to the proper
localtions, libvirtd and vdsmd restart fine, just the SSL ERROR.
Anyone have any ideas on how to solve this cert issue?
Thanks

Failed to connect to the host via ssh: root@192.168.4.17: Permission denied (publickey, gssapi-keyex, gssapi-with-mic, password).
by konstantinluschaev＠ya.ru
An attempt to deploy a new host fails. Deploy I see the following error in the deploy log:
192.168.4.17: Failed to connect to host via ssh: root(a)192.168.4.17 :
Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).
Despite the fact that the root user logs into the host via ssh from the ovirt-engine without any problems.
So I understand that ansible scripts cannot get through ssh.
Do you have any ideas about this?

oVirt over gluster: Replacing a dead host
by Gilboa Davara
Hello all,
I'm attempting to replace a dead host in a replica 2 + arbiter gluster
setup and replace it with a new host.
I've already set up a new host (same hostname..localdomain) and got into
the cluster.
$ gluster peer status
Number of Peers: 2
Hostname: office-wx-hv3-lab-gfs
Uuid: 4e13f796-b818-4e07-8523-d84eb0faa4f9
State: Peer in Cluster (Connected)
Hostname: office-wx-hv1-lab-gfs.localdomain <------ This is a new host.
Uuid: eee17c74-0d93-4f92-b81d-87f6b9c2204d
State: Peer in Cluster (Connected)
$ gluster volume info GV2Data
Volume Name: GV2Data
Type: Replicate
Volume ID: c1946fc2-ed94-4b9f-9da3-f0f1ee90f303
Status: Stopped
Snapshot Count: 0
Number of Bricks: 1 x (2 + 1) = 3
Transport-type: tcp
Bricks:
Brick1: office-wx-hv1-lab-gfs:/mnt/LogGFSData/brick <------ This is the
dead host.
Brick2: office-wx-hv2-lab-gfs:/mnt/LogGFSData/brick
Brick3: office-wx-hv3-lab-gfs:/mnt/LogGFSData/brick (arbiter)
...
Looking at the docs, it seems that I need to remove the dead brick.
$ gluster volume remove-brick GV2Data
office-wx-hv1-lab-gfs:/mnt/LogGFSData/brick start
Running remove-brick with cluster.force-migration enabled can result in
data corruption. It is safer to disable this option so that files that
receive writes during migration are not migrated.
Files that are not migrated can then be manually copied after the
remove-brick commit operation.
Do you want to continue with your current cluster.force-migration settings?
(y/n) y
volume remove-brick start: failed: Removing bricks from replicate
configuration is not allowed without reducing replica count explicitly
So I guess I need to drop from replica 2 + arbiter to replica 1 + arbiter
(?).
$ gluster volume remove-brick GV2Data replica 1
office-wx-hv1-lab-gfs:/mnt/LogGFSData/brick start
Running remove-brick with cluster.force-migration enabled can result in
data corruption. It is safer to disable this option so that files that
receive writes during migration are not migrated.
Files that are not migrated can then be manually copied after the
remove-brick commit operation.
Do you want to continue with your current cluster.force-migration settings?
(y/n) y
volume remove-brick start: failed: need 2(xN) bricks for reducing replica
count of the volume from 3 to 1
... What am I missing?

ovirt-aaa-jdbc-tool and Keycloak
by Gilboa Davara
Hello all,
I have a number of oVirt clusters that were recently upgraded to v.4.5.1.
As far as I can see, once keycloak is enabled, local users can no longer
login. (only admin@ovirt works).
Assuming I need to continue using local AAA users (created using
ovirt-aaa-jdbc-tool), should I disable keycloak support? How do I do it?
(engine-setup?).
