December 13, 2025Dec 13 Hello,After update to 7.2.2 I was trying to change some VM settings. I disabled auto start and tried to update RAM capacity of my VM. The update process hung and then my VM disappeared from VM manager UI. Any way to restore its settings? Or should I just recreate it and point it to the correct disk?This is the libvirt log:2025-12-13 13:23:28.807+0000: 33765: info : libvirt version: 11.7.0 2025-12-13 13:23:28.807+0000: 33765: info : hostname: DataServer 2025-12-13 13:23:28.807+0000: 33765: error : qemuProcessQMPLaunch:10104 : internal error: Failed to start QEMU binary /usr/local/sbin/qemu for probing: Start/autostart is disabled in VM settings. 2025-12-13 13:23:28.807+0000: 33765: warning : virQEMUCapsLogProbeFailure:5842 : Failed to probe capabilities for /usr/local/sbin/qemu: internal error: Failed to start QEMU binary /usr/local/sbin/qemu for probing: Start/autostart is disabled in VM settings. 2025-12-13 13:23:28.811+0000: 33765: error : qemuProcessQMPLaunch:10104 : internal error: Failed to start QEMU binary /usr/local/sbin/qemu for probing: Start/autostart is disabled in VM settings. 2025-12-13 13:23:28.811+0000: 33765: warning : virQEMUCapsLogProbeFailure:5842 : Failed to probe capabilities for /usr/local/sbin/qemu: internal error: Failed to start QEMU binary /usr/local/sbin/qemu for probing: Start/autostart is disabled in VM settings. 2025-12-13 13:23:28.811+0000: 33765: error : qemuAutostartDomain:187 : internal error: Failed to autostart VM 'Windows 11': internal error: Failed to start QEMU binary /usr/local/sbin/qemu for probing: Start/autostart is disabled in VM settings. 2025-12-13 13:33:50.212+0000: 33753: error : qemuProcessQMPLaunch:10104 : internal error: Failed to start QEMU binary /usr/local/sbin/qemu for probing: Start/autostart is disabled in VM settings. 2025-12-13 13:33:50.212+0000: 33753: warning : virQEMUCapsLogProbeFailure:5842 : Failed to probe capabilities for /usr/local/sbin/qemu: internal error: Failed to start QEMU binary /usr/local/sbin/qemu for probing: Start/autostart is disabled in VM settings. 2025-12-13 13:33:50.217+0000: 33754: error : qemuProcessQMPLaunch:10104 : internal error: Failed to start QEMU binary /usr/local/sbin/qemu for probing: Start/autostart is disabled in VM settings. 2025-12-13 13:33:50.217+0000: 33754: warning : virQEMUCapsLogProbeFailure:5842 : Failed to probe capabilities for /usr/local/sbin/qemu: internal error: Failed to start QEMU binary /usr/local/sbin/qemu for probing: Start/autostart is disabled in VM settings.

Posting the diagnostics in case you can see something as to why it happened. Server was not restarted since. Happened around 2025-12-13 13:23:28I also noticed that one of my docker containers was not starting due to errors in /etc/localtime. The reason was that unraid timezone information was lost during the update 7.1.4->7.2.2. Once I set the correct timezone it started up. Not sure if it is related to VM issue. dataserver-diagnostics-20251214-1527.zip
