[CentOS] Xen DomU console connection

Dom0 OS=CentOS-5.2_X86_64
Dom1 OS=CentOS-5.2_X86_64

I have a desktop machine running the xen kernel, Dom0.  I have created a
virtual machine on that host, Dom1.  From my console session on Dom0 I can
open a GUI console for Dom1 but I cannot resize the actual screen area. I
can make the virtual console window larger but the screen stays centered
at the same size while the margins increase in width.

I would like to simply switch my entire desktop display from the Dom0 to
Dom1 (together with the keyboard and mouse of course) and then back to
Dom0 again when I am done.  I suspect that this is not possible, but if it
is then surely someone here will know.

If I cannot actually switch desktops between domains then is there another
technique available to accomplish much the same thing?  I would like to
use Dom1 for software development using visual editors and such.  Running
these inside the virtual console window is not workable, mainly due to the
limited display size and the erratic behaviour of the mouse.
