Apologies in advance if I missed a required step & this is operator
error as it is my first attempt to use QEMU/Debian.


Running Guix on Debian 8.3, I set up qemu like this ...

su
apt-get update
apt-get upgrade
apt-get install qemu
apt-get install qemu-kvm
apt-get install libvirt-bin
adduser g1 kvm
adduser g1 libvirt


... then, as user g1, I checked that virsh commands work ...

g1@e3b:~/dev/vms$ virsh list --all
 Id    Name                           State
----------------------------------------------------

g1@e3b:~/dev/vms$ virsh --connect qemu:///system list --all
 Id    Name                           State
----------------------------------------------------

g1@e3b:~/dev/vms$ virsh version --daemon
Compiled against library: libvirt 1.2.9
Using library: libvirt 1.2.9
Using API: QEMU 1.2.9
Running hypervisor: QEMU 2.1.2
Running against daemon: 1.2.9


... then, using this version of guix ...

git branch -av | grep '* master'
* master                                  bae0636 bournish: Add 'wc' command.
g1@e3b:~/dev/guix$ stat /home/g1/.config/guix/latest | grep File:
  File: ‘/home/g1/.config/guix/latest’ -> ‘../../dev/guix’


... I tried making a guix vm ...
