help with Xen 4.1 on -current

[Jeff Rizzo <riz%tastylime.net@localhost>]

I don't follow Xen development all that closely, and I've never used it 
under Linux - so I'm a little lost while trying out Xen 4.1 on my NetBSD 
5.99.51 amd64 dom0.

This system was working fine with Xen 3.3 - I have a PV domU config 
(NetBSD 5.1-ish) that was running, and that I haven't changed the config 
file, kernel, or anything else.

I have the latest xenkernel41 and xentools41 packages installed.  The 
system boots with the Xen4.1 kernel (although I have to gunzip it to get 
it to work - I had the same issue with Xen3, though, so that's not new.  
Bootloader issue, maybe?), and I have the following in rc.conf:

xend=YES

... I copied all the rc files to /etc/rc.d, and removed older versions.  
It's unclear to me if xend is fully starting, as I see this:

xenserver1:riz  /usr/pkg/etc/xen> ps ax |grep xen
 278 ?     I    0:00.22 /usr/pkg/sbin/xenstored --pid-file 
/var/run/xenstored.p
 286 ?     Isl  0:00.01 /usr/pkg/sbin/xenbackendd
 291 ?     I    0:00.00 /usr/pkg/bin/python2.6 /usr/pkg/sbin/xend start
 293 ?     Il   0:00.00 /usr/pkg/sbin/xenconsoled
 303 ?     Il   0:01.19 /usr/pkg/bin/python2.6 /usr/pkg/sbin/xend start

In /var/log/xen/xend-debug.log, I see this (only):

Xend started at Fri May 20 13:16:35 2011.
brctl: not found

/usr/pkg/lib/python2.6/site-packages/xen/xend/XendAPI.py:551: 
DeprecationWarning: object.__new__() takes no parameters
  return object.__new__(cls, *args, **kwds)

Things sort-of look ok; but when I try to use 'xm' to start my domU, it 
*seems* to work, but the domain isn't running - and when I check 
xend.log, it seems to have crashed:

xenserver1# xm create -c boogers

From xend.log:

...any ideas?
