For what its worth: I have the same issue with Ubuntu 22.04.4 LTS (Desktop).
Working kernel (i.e. VM in Virtualbox 6.1 boots): Linux 5.15.0-1061-gke Broken kernel (i.e. VM no longer boots): Linux 5.15.0-1062-gke Workaround: Installed Virtualbox 7 from the Oracle PPA repository and migrated VM with some teething problems. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2073267 Title: Guru meditation on VM start To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe-5.15/+bug/2073267/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
