newfs fails in DOMU during install

[Etienne Labaume <etienne.labaume%free.fr@localhost>]

Hello all,

I'm running NetBSD/amd64 current (snapshot 200803210000Z) and installed
xentools3, xentools3-hvm and xenkernel3. Trying to install a NetBSD DOMU, it
fails while writing the new root filesystem with the error message:

newfs: block size `0' (0) is less than the minimum (4096).

This xbd0 filesystem is a file created with:

dd=if=/dev/zero of=test.img bs=1m count=128

I don't quite get what I'm doing wrong ? For your information, the config file
for that domain is just consisting of those lines:

kernel = "/usr/pkg/xen3-kernel/kern-INSTALL_XEN3_DOMU.gz"
memory = 128
name = "test"
vif = [ 'mac=00:16:3e:00:00:11, bridge=bridge0' ]
disk = [ 'file:/var/xen/test.img,0x1,w' , 'phy:/dev/wd1p,0x2,w' ]
extra = ""
