Not the original supplicant but reproduced the issue ;-) ...

libvirt installad in system ...
g1@g1 ~/src/guix/doc$ guix package -p /run/current-system/profile -I | grep virt
libvirt	4.0.0	out
/gnu/store/437rasdksqspz895bq087sg4vnwnif6x-libvirt-4.0.0

... virt-manager installed in profile ...
g1@g1 ~/src/guix/doc$ guix package -I | grep virt
virt-viewer	5.0	out	/gnu/store/ybwlzdz1h37f0rgvxm5y0gbx94cfbk2x-virt-viewer-5.0
virt-manager	1.4.3	out	/gnu/store/w0zzl85zvlc2jyg278b5dwggxrjpn2cy-virt-manager-1.4.3

vm_image created like this (config v1.scm attached) ...
cp -f $(guix system vm-image -M 4 -c 4 $VMDIR/v1.scm 2>	$VMDIR/vm.log) $VMDIR/vm.img

I ran virt-manager and used the "Create a new virtual machine" dialogue
to select the image which produced this error ...
"Unable to complete install: 'Failed to connect socket to
'/var/run/libvirt/virtlogd-sock': No such file or directory'

... these details were available ...
