I'm trying to generate a disk image of Guix.
The image creation process goes fine until the start of QEMU:

	creating raw image of 2607.99 MiB...

My host system is Void Linux (which I don't know so well).
Permissions for /dev/kvm seem to be correct:

	> ls -l /dev/kvm
	crw-rw----   1 root           kvm             0 2018-03-03 14:56 /dev/kvm

My user is part of the kvm group.  Also the module seems to be loaded fine:

	> lsmod | grep kvm
	kvm_intel             225280  0
	kvm                   630784  1 kvm_intel
	irqbypass              16384  1 kvm

Not sure what's wrong.  I am not very familiar with QEMU / KVM I'm afraid...
Any clue?

Besides, and maybe unrelated, some certificates seem to be missing.  Any
idea how that could happen?
