Hello Guix,

EFI bootloader configuration causes problems to test with 'system vm'
before 'reconfigure'.

To reproduce it replace default bootloader expression with following
snippet in gnu/system/examples/vm-image.tmpl

(bootloader (bootloader-configuration
(bootloader grub-efi-bootloader)
(target "/boot/efi")))

Toggle snippet (19 lines)

This is because `guix system vm` is not currently UEFI enabled, so GRUB
tries to install for a normal PC BIOS.

The fix would be to make the various QEMU invocations in (gnu system vm)
take a #:firmware parameter that passes something along the lines of
'-bios #$(file-append ovmf "/share/ovmf/firmware/ovmf_x64.bin")' to the
QEMU command-line, and update other scripts to take advantage.

It's on my ever-growing TODO list and would be nice to have indeed.

Perhaps by adding it to <virtual-machine> records we’d make it less
annoying to pass around? Or are there other places that would still
need extra care?

Another option, in the meantime is this:

That’s what I do manually anyway.

WDYT? If that’s fine with you, I can commit it.

Thanks,

Sorry for late response, still going through a backlog! I think
<virtual-machine> should be sufficient, did not do a lot of research.

Pushed as 9b396c0cabb086746cbe4ec20d4ae0d79962d758 (along with the
missing #:use-module clause that Oleg reported.)

I’m closing this bug. We can create a new issue when we add support for
UEFI in VMs.

This is expected: there’s no partition with that label in the VM.

You have to comment out the ‘file-system’ declaration because it doesn’t
make sense inside the VM. Perhaps ‘virtualized-operating-system’ could
do it automatically as well, not sure.

HTH,
Ludo’.
