Domain crash and Cannot emulate e8
Hello,

I am new in xen world.

I have a bug.

My configuration:
Fedora Core 6 x86_64 with Core 2 Duo (6700) on a P965 Intel motherboard.
The VT technology is ON in BIOS.

I have try to install a Windows XP SP2 on a full virtualiztion.
I have succes for the first step : windows CD boot and copy files for
installation . But when the windows restart the domain crash.

Trace are interesting.

The xen dmesg intersting part:

These messages aren't necessarily errors although they may be significant.

This is a triple fault in the guest - which is pretty bad!

Can you try to reproduce this with 3.0.3-0?


cheers,
