Hi Alex !
After a bit of digging as to why the karmic installer dies, I found out
that you don't set the right SRR1 bits when forwarding a program check
exception to the guest.
I also did a couple of minor fixups (though the s/mtmsr/mtmsrd may not
be necessary, I think the clearing of HID5 is). Patch below, haven't had
a chance to clean it up into a proper submission yet.
I didn't go very much further yet with the karmic graphical installer,
but that isn't a surprise. I'll try the text one as soon as I get to d/l
the alternate ISO.
Cheers,
Ben.
