Hi guys.
I've barely started, trying to deploy my first oVirt and I get:

Please help connecting to serial console - <urlopen error [SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:897)>
by morgan cox
Hi.
I have an Ovirt 4.4.10 system - its a standalone setup (not hosted engine) - ovirt-vmconsole-proxy-sshd is running on the engine.
Presently I just cannot connect via port 2222.
I have never been able to connect via serial console and require help connecting, pretty sure its due to not using the right key/cert ..
I have tried to follow something like this -> https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.3/...
i.e I created a serialconsole key - added to my user in Ovirt UI (as my user 'mcox')
however if I try
# ssh -t -i /home/mcox/.ssh/ -p 2222 ng2-ovirt-mgmt1 -l ovirt-vmconsole
I get
ovirt-vmconsole(a)10.168.69.200: Permission denied (publickey).
I get in ovirt-vmconsole-proxy-sshd logs

Am I using the right key ?
I have tried to troubleshoot this - if I use

no snapshot function in VM portal
by Christoph Köhler
Hi!
On a fresh Version 4.5.4-1.el8: in the vm portal are no snapshot
operations possible - not for an user_vm_manager and not for a
super_user. We have imported VMs from 4.3 with exisiting snapshots.
These are listed for the users in the snapshot box but there is also no
operation possible for them.
Does anyone has a hint?
Greetings!

Ovirt node disk broken
by marcel d'heureuse
Hi all,
On a single Server the node disk is broken and I have to replace it.
The glusterfs configuration is also gone but the glusterfs directorys are existing on a separate available disk.
Did I have a Chance to install the ovirt Node on a New disk and make the old glusterfs running and also the 7 vms included the hosted engine?
I can also deploy a New hosted engine but can I than import the existing gluster disk from the old Installation?
I have installed the node and also mount the gluster_bricks but to make the volumes available I have not found any command.
It is an ovirt 4.3.10 Installation.
Is there any chance to save some time. The data inside the vms are good to have.

The underlying storage is NFS on top of Ceph (which is not listed in the ovirt documentation). Does this ring any bell to anybody?
Please let me know if you need more information in this regard or contents from any of the log files.

cannot update expired engine certificates?
by michael.d1.holt＠lmco.com
ovirt 4.4.10.x, using self signed certificates with a self hosted engine. apache certs expired, renewed manually via guides provided by RHEL and oVirt using the pki_enroll_pkcs12.sh script. Engine certs are also expired and cannot update certs via gui and no option to renew the certs when running using engine-setup --offline. The error I am getting is a VDSM certificate error on the hosted engine in the engine.log file. I have attempted to manually run the pki_enroll_pkcs12.sh script with "engine" in the name and the subject of the previous engine.cer file with no luck. I copied the p12, key and cert from that attempt into the engine.cer, engine.p12 and engine_id_rsa files, but when booting the hosted engine VM, the first error in the engine.log is "VDC cannot find the engine certificate". This also breaks my access to the web interface for oVirt administration. When the expired engine certs are restored, I have GUI access but still see the VDSM errors on the ovirt-engine. That I hav
e web access with the expired engine certs indicate to me that the apache certificates are correct (but i could be wrong in that evaluation).
Basically i am looking for a way to either force the enroll pki option in the engine-setup --offline script or manually generate and update the engine.cer, engine.p12 (and if needed, but i couldn't determine where it was used) the engine_id_rsa key.
