Thank you for the feedback!
I managed to make foot terminal working in my setup -- the issue was in
lack of compositor ( weston in my case) on the guest, looks like it's the
common issue for wayland programs, so now I have competitive advantage over
virtio-gpu setup :)
I also think that having socket-only approach in Spectrum is not a bad idea
cause it is enabling remote access and networking easy for virtual
machines and applications.
