Windows 11 host Ubuntu 21.04 virtual machine boot problems

Post by art4science »

Hi, when I upgraded VB to Windows 11 version 6.1.32, all of my virtualbox VM's crashed at boot. After I downgraded back to VB 6.1.30 they all ran, but when the VM's resumed from a saved state, I got a critical error has occurred message"

The VM's run fine when booted from a powered off state.

Saved states don't survive a Virtualbox version change. You either have to start the saved-state VMs and shut them down fully before up/downgrading Virtualbox, or right-click the VM in the list and discard the saved state, whereupon the VM will start like it lost power, with unsaved-to-disk data lost.
