I use a GUI installer for many MANY things and I never have used KDE or
GNOME or any other full blown desktop environment. That's like using a
howitzer to hunt pigeons. use the vncserver command.
To create and x windows session with enough color depth to display most GUI
stuff use something like:
vncserver -depth 24 -geometry 1024x768 :0
And to kill session :0 when done:
vncserver -kill :0
You can then install a vnc client (vncviewwer is what I use) to aim at your
target image and get the gui.
I've also used tight VNC, which only ships you the pixels that have
changed, rather than the whole screen. MIght be a better choice.
You can also just aim a web browser at your linux guest on port 580{port in
vncserver command} which in this case would be 0. http://{guestname}:5800
I've found the browser session method a little less stable than using
vncviewer, but your mileage may vary.

KDE?
Yep, you can run it, but everytime I bring up KDE, it takes about 40%
of our 60 MIP processor. There is very little that you ever need a
desktop manager for that can't be done via command line. But it is
really nice to have as a fall back to install some product.
But after the product is installed, then bring down KDE!
I think a year or so ago, DB2/UDB required a gui screen for the install
(just to ask one question).

You Linux image is way too big and you're probably seeing VM getting
tired paging it in and out. Try reducing it to 384MB. You will also
want to turn off timer ticks. I don't remember exactly what it is you
need to echo to where in /proc, but I'm sure someone else does.
The other thing that's hurting you is KDE. Why are you running a
desktop manager on your 390? Turn *off* X entirely--you don't have a
local display there anyway. Again, I don't remember what runlevel
"services, no X" (I think it's "2", but I won't swear to that) is in
SuSE, but I'm sure someone does.
