HAOS as KVM on RaspberryPi5 with Ubuntu Server 24.10

Installation

Hi,

i’m trying to install home assistant os as a kvm on a raspberrypi5 with ubuntu server 24.10.

If i start the kvm as described here

i’m stuck in the UEFI interactive shell.

I enter “\EFI\BOOT\bootx64.efi” i just get an “Command Error Status: Access Denied”

What am i doing wrong?

Not so sure I can help, but willing to try …wanted to ask, which KVM install method did you use virt-manager or virt-install? I’m wondering if your install is trying to use secure boot …

I use virt-install.
I tried to turn secure boot off via virsh edit, but i can’t save the configuration because there seems to be no supported efi installed.
qemu-efi-aarch64 is installed on the raspi

Maybe take a look at this post to see if it helps (turned off secure boot in UEFI shell).

If that doesn’t work, then here is another thing to try… in your virt-install add the flag (from man virt-install):

--boot loader=/.../OVMF_CODE.fd,loader.readonly=yes,loader.type=pflash,nvram.template=/.../OVMF_VARS.fd,loader_secure=no
              Specify  that  the virtual machine use the custom OVMF binary as boot firmware, mapped as a virtual flash chip. In addition, request
              that libvirt instantiate the VM-specific UEFI varstore from the custom "/.../OVMF_VARS.fd" varstore template.  This  is  the  recom‐
              mended  UEFI  setup,  and should be used if --boot uefi doesn't know about your UEFI binaries.

but goto your /usr/share/OVMF/ directory and look to see if these OVMF files are there, and if not then pick one that doesn’t have secure or secboot in their name.
