Could not run HVM domain on the latest xen-unstable.hg and Barcelona.

[Yoshisato YANAGISAWA <yanagisawa.yoshisato@lab.ntt.co.jp>]

Hi all,

Does anybody have tested the latest xen-unstable.hg with an HVM domain
on AMD Barcelona Opteron?
I cloned xen-unstable.hg today (2009-03-10 JST), made config file for
booting an OS image from CD-ROM, and tried to run an HVM domain.
However, it stops running while booting.

According to the vnc, the virtual machine displayed following message:

According to the serial console, I also saw following message:

I came across this problem with AMD Quad-Core Opteron(tm) 2356 on Dell
PowerEdge R805.  However, this kind of problem did not happened on the
another machine I use (Intel Xeon 5130).

Does anybody know how to fix this problem or how to analyze it?

Thank you in advance,
