I've tried X11 and VNC.  X11 is easier to use and maintain if you
already have SSH access, but I prefer VNC if it's available.

X11 over a remote (e.g., VPN over the Internet) connection is usually no
fun at all.  However, if you have a local 1G link to the servers, then
the X11 performance might be tolerable, in which case the simplicity of
X11 might beat VNC's performance.

FWIW, QEMU comes with a built-in VNC server feature, which makes it even
easier to use VNC in this use case.  See for example:

For a VNC client, in Guix we have Vinagre, which works fine for me.
