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,
