Guru meditation on Autostart

Post by SenorClean »

I'm running Virtualbox on an Ubuntu 22.04 host, and have 2 VMs (Ubuntu 22.04 and Windows Server 2016) that autostart.

I've recently upgraded from VBox 6.1 to 7.0.4 - the VMs booted fine following the upgrade, but if I reboot the system - they both end up in Guru Meditation.
If I kill the processes and boot the machines, they seem OK.
In the logs I see: VCPU0: Guru Meditation -37 (VERR_NOT_SUPPORTED)

Any ideas what is going on and how I might be able to solve it?
I also had this issue on the initial 7.0 release, and rolled back to 6.1 for a while.

I would attend to some of the basics, see if it helps:

You have plenty of RAM, so I'd increase VM RAM to 2GB and graphics RAM to 128MB.

I would also eject the Guest Additions CD, to stop the VM from trying to boot that.

On your Linux host, probably another hypervisor (e.g. KVM) is already running. Keep it from running simultaneously with VirtualBox VMs.

Ahh - you're probably right, thanks. I did look at migrating to KVM a little while ago so have some of that stuff running - I'll tidy it up.

EDIT: So far, so good
