Cannot run or Create Centos VMs on an Ubuntu 22.04 host

Post by AdamL »

Hello All


I have VB 7.0.4 running on an Ubuntu 22.04 host. VB 7.0.4 has been running for several months perfectly.

I recently upgraded to VB 7.0.6, however that stopped me from being able to ssh into my VMs.
So I removed VB and reinstalled 7.0.4.

Following that I cannot start any VM, or even create a new Centos 7 VM. I see a "critical error" message with advice to contact this forum:


An excerpt from the VBox.log file shows this:

Code: Select all

00:00:01.020905 Console: Machine state changed to 'Running'
00:00:01.021210 Changing the VM state from 'RUNNING' to 'GURU_MEDITATION'
00:00:01.021232 Console: Machine state changed to 'Stuck'

00:00:01.022368 !!
00:00:01.022369 !! {cpumguest, verbose}
00:00:01.022370 !!

The complete log file is attached.
Does any one have a clue what may cause this?


Thanks - AdamL

You have KVM running on your host Linux. Virtualbox can't run while KVM is running.
