Thanks.  I was confused which is the current kernel while working between
two machines.  My bad.  When I used correctly recent 2007/06/15 kernel,
NetBSD DomU works good with xen3.1.


However, I'm having read_psl problem now.  hehe.  It is very similar
problem I reported at May 26th.  At that time, I just rollbacked my
netbsd to Apr 30th.  This time, I need the recent kernel for Xen 3.1,
so working to find the source of problem.

Last time, I was having problem when I try to run WinXP.  However,
this time I'm having from both Dom0 while trying to run WinXP and NetBSD
DomU while operating DomU.  Here is a trace from db.

Now, I'm trying to find the modified source codes causing this problem
between 4/30 and 5/20.  I'll be back if I find something.
