Re: [Xen-users] boot a existing windows in hvm domain

["Brady Chen" <chenchp@xxxxxxxxx>]

Hi Z24, AL,
ccing tygrawy@gazeta,pl, for I found he got the same issue.

I tried in ThinkPad T60,
/dev/sda1 -- windows
/dev/sda2 -- Linux + Xen 3.1.0

in xen guest, the whole sda is mapped to virtual hda.
disk = [ 'phy:/dev/sda, hda, w' ]

I could see the grub menu in xen guest, and could boot in to the linux
(you know, it's re-enter into the linux), but when I select windows
from grub menu, it will hang after print "chainloader +1"
the xen dmesg shows:
(XEN) HVM1: Trap (0x6) while in real mode
(XEN) HVM1: eax         D00 ecx           0 edx         71F ebx         71E

tygrawy:
I found you have the same issue months ago, have you find out the
reason? Thank you very much.
