Typically, I have now run winXP for 2 hours after it last bombed with 3
mins to go on the installation.  WinXP started up fine however, despite
not finishing the install properly.  It has not crashed so far :( so I
cannot paste the text of the core dump here.  I will post it if I get
the error again.

To answer your other questions, I run Ubuntu amd64 version and kvm is
from the Feisty repository and when I run it with -h option it says it
is version 0.9.0 but that was for qemu I guess.  kvm is in the universe
repository in fesity and is version 16.  How can I determine if VT is
really being used because it is running very slow on window
redrawing/mouse movement?
