xen3 domU support has been merged to the netbsd-3 branch according to
netbsd.org.  So I went to netbsd-daily
(.../NetBSD-daily/netbsd-3/200606090000Z/i386/binary/), fetched the bits
and tried to boot the installer kernel.  Didn't work.  Any idea what I'm
doing wrong?

my config file looks like this:

------------- cut here ---------------
# general
name    = "netbsd";
memory  = 128;

# booting
kernel  = "/vm/netbsd/netbsd-INSTALL_XEN3_U.gz";
on_crash = "destroy";

# virtual harddisk
disk = [ 'phy:xen/netbsd,0,w' ];

# virtual network
vif = [ 'mac=aa:00:62:73:64:00' ];
dhcp = "dhcp";

Trying to boot results in this:

xen says (recent -testing tree):
(XEN) DOM9: (file=mm.c, line=1082) Bad L1 flags 800

The "Kernel symbol table missing!" message looks suspious to me as there
is a special loadbsdsymtab() function in the domain builder, so it
should be there, no?
