I believe the "EFI stub: ERROR: FIRMWARE BUG: kernel image not aligned on 64k boundary" that was reported on this bug is not what is preventing the VM from booting. If you look into the full log you provided, that message is logged both on the boot that succeeded and in the one that got stuck.
I believe whatever was done in the VM in between these reboots, might have caused the problem you are observing. There's also a known problem on linux-oracle kernel that prevents you from seeing the serial console. That is being fixed for Focal images on the linux-oracle 5.13.0.1023.28~20.04.1 kernel, which is currenlty in focal-proposed. If this is something you can reproduce with Focal images, using the kernel from proposed might help you see what is really preventing the VM from starting. We'll review the 'kernel image not aligned on 64k boundary' error anyway to assess what might be causing it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1944574 Title: EFI stub: ERROR: FIRMWARE BUG: kernel image not aligned on 64k boundary To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-oracle/+bug/1944574/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
