NetBSD 5.0_BETA XEN2 DOMU doesn't boot

[Stephen Borrill <netbsd%precedence.co.uk@localhost>]

I've got a 3.1 XEN2 dom0 which I'm running 3.1 and 4.0 development domUs 
on. When I tried to get NetBSD 5.0_BETA going, I didn't get very far.

xen# xm create -c devel5
Using config file "devel5".
Started domain devel5, console on port 9615
(61, 'Connection refused')
Error: Error connecting to xend, is xend running?

The network and xbd seems to attach OK:
xvif15.0: Ethernet address aa:00:00:51:02:f5
xbd backend: attach device wd0g (size 83885949) for domain 15
xbd backend: detach device wd0g for domain 15

The same configuration file works with a 4.0 INSTALL_XEN2_DOMU kernel.
