I am using Virtualbox 7.0.12_Ubuntur159484 at Ubuntu 22.04 as a host and three virtualbox guests, all Ubuntu 22.04. Very unfrequent it happens that one of the VMs freezes during shutdown. I can see in the log, that the log that the VM has shutdown successfully but the window does not close:
09:16:49.393556 GIM: KVM: Resetting MSRs
09:16:49.401425 vmmR3LogFlusher: Terminating (VERR_OBJECT_DESTROYED)
09:16:49.401543 Changing the VM state from 'DESTROYING' to 'TERMINATED'
09:16:49.407104 Console: Machine state changed to 'PoweredOff'
09:16:49.407268 GUI: Request to close Runtime UI because VM is powered off already.
09:16:49.407274 GUI: Passing request to close Runtime UI from UI session to UI machine.
09:16:49.425025 GUI: UICommon: Handling aboutToQuit request..
Then the other VMs freeze as well and I cannot shutdown them. When I try to shutdown the host system, it runs into problems as well:
Jan 22 19:52:47 host systemd[1]: virtualbox.service: Stopping timed out. Terminating.
Jan 22 19:52:47 host systemd[1]: virtualbox.service: Control process exited, code=killed, status=15/TERM
Jan 22 19:52:47 host systemd[1]: virtualbox.service: Failed with result 'timeout'.
Jan 22 19:52:47 host systemd[1]: virtualbox.service: Unit process 409438 (pidof) remains running after unit stopped.
Is this a known issue? Where can I find more information on the causes of the problem?
