Hey Tim, Deploying an OVN-enabled cluster is not that trivial. There are many caveats to make it run. Is there any special use case you need to address to use OVS/OVN?

Importing Storage Domain's Export from one Data Center to Another

Is it possible to perform disaster recovery importing a Storage Domain's Export from one Data Center to another in a manually fashion without Ansible? I'm trying to import Data Center 1's Storage Domain Export by cloning the storage domain export and importing it into Data Center 2's environment through IP address & NFS name within the oVirt's web portal. However, I receive this error message: there is no storage domain under the specified path. Below is what I have done to tried to troubleshoot the issue. After looking into the documentation, I haven't seen information for this method. Should I consider another option? Is there a preferred way of testing DR within an environment? -I have detach both of the export storage domains from both data centers before importing the cloned export. -Changing import settings -I have adjusted the metadata information within the cloned export after mounting it and reviewing the logs.

Migration of oVirt Engine and Hosts from CentOS 8 to CentOS 9
by narutospinal＠gmail.com 25 Oct '24

Dear, I would like help with the following question: I need to migrate my oVirt Engine and oVirt Hosts from CentOS 8 to CentOS 9. My plan is to back up the database using the engine-backup command. For example: engine-backup --mode=backup --file=db_backup My next step will be to install the oVirt Engine on CentOS 9 and restore the backup. For example: engine-backup --mode=restore --file=db_backup --log=backup_restore.log --change-db-credentials --db-host=didi-lap --db-user=engine --db-password=your_password --db-name=engine Finally, I will add a new oVirt Host with CentOS 9 and migrate the virtual machines. Are there any considerations I should be aware of? Could you please guide me?

I did a fresh install but what is username and password?

Hello. Why there is no info on oVirt website about installation process and how to login? Ideas like: ovirt-aaa-jdbc-tool user password-reset admin --password-valid-to="2035-12-31 12:00:00Z" are not helpfull because ovirt-aaa-jdbc-tool: command not found Is there a way to use this system? I have no idea why Linus Torvalds don't like Debian... it is a loot simpler than the other systems.

Re: Latest 4.5.5 centos node install username password not working.

# ovirt-aaa-jdbc-tool -bash: ovirt-aaa-jdbc-tool: command not found I did manage to login to Cockpit using IP address: https://{ip}:9090/={ip}/system/services It had problems with hostname. I'm not sure why. It may be related with hardware firewall configuration and multiple vlans I use. Cockpit works with root and password but only if ip address is given. I did also try using login with @ sight and it didn't help. Command ovirt-aaa-jdbc-tool doesn't work. I also can't install nano, "ovirt-aaa-jdbc-tool", and mc. But internet connection is working and I can resolve DNS addresses. Maybe RHEL type of Linux is not so bad but I'm not familiar with it.

Also can the engine be installed from the node via the cockpit still? How can I get logged in to do this? I have used 4.3 and didnt have any of these problems. It was really simple to do. Any suggestions? grazie

Lost console access to VMs after updating
by malcolm.strydom＠pacxa.com 24 Oct '24

We have a couple OLVM instances. Completely separate with their own managers (ovirt-engine). One is lab and one is prod. I updated the lab engine from 4.5.4-1.0.31.el8 to 4.5.5-1.22.el8 and as soon as that was done and it rebooted I no longer can open VM consoles. This was the update process followed: https://docs.oracle.com/en/virtualization/oracle-linux-virtualization-manag… In troubleshooting I checked for the SASL db which appears to be /etc/libvirt/passwd.db # grep sasldb_path /etc/sasl2/libvirt.conf sasldb_path: /etc/libvirt/passwd.db I can verify the vdsm user and realm is in there # sasldblistusers2 -f /etc/libvirt/passwd.db vdsm@ovirt: userPassword We are using noVNC in the browser and when I click on a vm and then console it opens a new window and just has the "connecting" message. I switched to Native VNC client and downloaded the console.vv file which looks normal inside and when I try and open it with vnc viewer or remote-viewer etc. I get a window that connects, authenticates with the password found in the console.vv but then presented with a display that says "Guest has not initialized the display (yet)." Thinking perhaps I need to update the KVM hosts too I proceeded with the update document listed above but even with the hosts updated nothing has changed. If I tail /var/log/messages when opening a console connection all I see is this: Oct 14 10:33:52 olvm2 kernel: sd 6:0:0:1: Warning! Received an indication that the LUN reached a thin provisioning soft threshold. Oct 14 10:34:41 olvm2 saslpasswd2[55701]: error deleting entry from sasldb: BDB0073 DB_NOTFOUND: No matching key/data pair found Oct 14 10:34:41 olvm2 saslpasswd2[55701]: error deleting entry from sasldb: BDB0073 DB_NOTFOUND: No matching key/data pair found Oct 14 10:34:41 olvm2 saslpasswd2[55701]: error deleting entry from sasldb: BDB0073 DB_NOTFOUND: No matching key/data pair found Oct 14 10:34:41 olvm2 saslpasswd2[55701]: error deleting entry from sasldb: BDB0073 DB_NOTFOUND: No matching key/data pair found I checked the production OLVM cluster which has not been updated and has a properly functioning vnc consoles and it produces the exact same errors shown above in the logs when opening a console. So I don't think that error is the cause if the issue although likely something that needs to be fixed. If I check the VM guest log when opening a console I get nothing. tail -f /var/log/libvirt/qemu/<vm_hostname>.log Has anyone else run into this issue when updating? Any ideas on what more I can look at or troubleshoot? Thanks Malcolm
