OK.

I think it's just a performance issue. As far as I know, there is no
longer great difference
between hvm and pv guest in XEN.

I don't think so. I have a windows-7 (but also a windows-xp) and a
CentOS domU (not hvm)
both using videoram=16 and stdvga=1, and there is no problem. High
resolution in both cases.

This happens to me only with this opensuse hvm guest. Now I've finally
got the setup under
qemu-system-x86_64 system working, so, I will see what will happen in
this case, when
I will boot the domU as a PV guest and not hvm.

mmmh.. So the screen resolution limitation is not related to this problem...
interesting and much more confusing.

I will let you know.

Thank you.
