Bug Description
When attempting to install Gutsy as a KVM guest, you are unable to do so unless disabling KVM support in qemu.
This causes the installation to preform VERY slowly indeed, however, once installed and booted, Gutsy preforms very well indeed.
My system:
Ubuntu 7.04 (Running custom Core2 kernel 2.6.22.6)
KVM-40 (Compiled from latest tarballs)
Intel E6600 Quad
I do not have a lot of information as to the cause, however the following may or may not be fully correct: (This is information I have attempted to understand from #kvm)
That this problem (may) only show when using kvm-intel (due to sw emulation (needs confirmation)), but not on kvm-amd
That this problem does not happen when installing SLEx10 guests (according to someone on irc) (I will attempt to test this tonight)
Any more information anyone can add to this?

This is a problem because intel hw does not provide big real mode, and expects software to handle it. Gfxboot causes the installer to stop at the gfx boot screen. According to #kvm, suse has a patch in gfxboot that detects kvm install and does not attempt to use big real mode, and allows things to get past this issue. The problem with -no-kvm installs is that it is _very_ slow.
Note, this affects xen guest installation as well.
