Title:
disk-kvm.img aren't UEFI bootable
Status in cloud-images:
New
Status in linux-kvm package in Ubuntu:
New
Bug description:
The `disk-kvm.img` images which are to be preferred when run under
virtualization, completely fail to boot under UEFI.
This is a critical issue as those are the images that LXD is now
pulling by default.
User report on the LXD side: https://github.com/lxc/lxd/issues/7224
Note that the non optimized images boot just fine (disk1.img).
I've reproduced this issue with:
- wget
http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-disk-kvm.img
- qemu-system-x86_64 -bios /usr/share/ovmf/OVMF.fd -hda
focal-server-cloudimg-amd64-disk-kvm.img -m 1G
On the graphical console, you'll see EDK2 load (TianoCore) followed by basic
boot messages and then a message from grub (error: can't find command
`hwmatch`).
Those also appear on successful boots of other images so I don't think
there's anything concerning that. However it'll hang indefinitely and eat up
all your CPU.
Switching to the text console view (serial0), you'll see the same
issue as that LXD report:
BdsDxe: failed to load Boot0001 "UEFI QEMU DVD-ROM QM00003 " from

If booting in a SecureBoot enabled environment, you instead get a
`Access Denied` at kernel loading time, indicating that the kernel
binary isn't a normal signed kernel. That has the same result (boot
hangs) but without the crash message.
