Just to chime in here: definitely do this if your guest supports it (I think
most Linux guests don't, but Windows does). It makes interaction with the
guest much more smooth: the mouse pointer in the guest lines up exactly with
where you move the mouse in the host *and* it lets you have "grabless"
operation (move the mouse freely in and out of the VM's window without using
any funny key combos).
If you have a Windows version that supports remote desktop, you might find it
better to connect to it using the Linux rdesktop client. If you use
http://www.cendio.com/seamlessrdp/ seamless RDP you can even have it
integrate with your Linux window manager (each Windows app has a separate
Window in dom0).

Exactly what I was going to say :-)
Also, you could investigate using Nomachine X to talk to the domUs (it can
also share printing, sound, files etc in an easy way - if you can get it to
work. I've used the FreeNX server but getting it to work was difficult, and
I couldn't make the advanced features behave - that was a while ago, though)
but you probably won't find many advantages over just using X11 over SSH in
the local case.
X forwarding over SSH has the additional benefit that it'll integrate with
your local window manager.
Cheers,
Mark
