Malcom, here the solution to your actual issue: Replace the following file with the attached one: # /etc/httpd/conf.d/olvm45-security-fixes.conf The final fix will be there with release ending with .23. Restart ovirt-engine and httpd services: # systemctl daemon-reload # systemctl restart ovirt-engine # systemctl restart httpd Simon On Oct 14, 2024, at 11:04 PM, Marcos Sungaila via Users <users(a)ovirt.org&gt; wrote: Hi Malcolm, Select the Cluster line at Compute > Cluster and edit it. Then check if in the Console left tab, the Enable VNC Encryption is set. If enabled, you will need to disable it, and using the web UI, put a host into Maintenance mode, then click the Installation button > Reinstall.

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-man... 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?
