Xen3 domU crashes

[Martti Kuparinen <martti.kuparinen%iki.fi@localhost>]

I'm continuing my Xen 2 to Xen 3 transtition project but I can't start even a 
simple domU. Here's what I've done so far:

(sources updated this morning so I have e.g. IPF 4.1.20)

ROOT xen3:~> uname -srm

ROOT xen3:~> ls -lh /xen/kernel/ /xen/vm/

Here's my configuration file:

#kernel = "/xen/kernel/netbsd-XEN3_DOMU.gz"
kernel = "/xen/kernel/netbsd-INSTALL_XEN3_DOMU.gz"
memory = 256
name = "netbsd1"
vif = [ 'mac=aa:00:00:99:99:01, bridge=bridge2' ]
disk = [ 'file:/xen/vm/netbsd1,0x1,w' ]
extra = ""

Now, I'm trying to start the domain with

ROOT xen3:~> xm create netbsd1 -c
Using config file "/root/netbsd1".
Started domain netbsd1
xenconsole: Could not read tty from store: No such file or directory

ROOT xen3:~> xm list

This is from /var/log/xen/xend.log
