Please make sure the guixbuild* user accounts have write permission for
/dev/kvm.
Usually, /dev/kvm is has “kvm” as its group and is group-writable. So
all you need is to add the guixbuild* users to the “kvm” group.
The manual mentions this pitfall (info "(guix) Invoking guix system")
but I guess it’s easily missed.
Thanks,
Ludo’.
