Hello Guix,
I try to use virt-manager for connection over SSH from Linux Mint to
GuixSD running libvirt.
Seems we need to package netcat which includes =E2=80=98-U=E2=80=99 option:

Hi Oleg,

> Try `nc --help' for more information.: Input/output error
There are several implementation of Netcat, and presumably libvirt
expects a different one.
Could you check which implementation you have on other distros?
TIA,
