Juergen, what error do you get if you comment out the kernel
= "/boot/vmlinuz-2.6" and uncomment the netbsd-INSTALL_XEN3_DOMU line?

Actually, you don't need HVM in this case: the NetBSD install kernel image for
Xen 3 can ferret around in the ISO filesystem using the paravirtualised VBD
and extract all the necessary stuff. I did it a few months ago - it's
actually quite impressive that the install (more or less) Just Works like
this.

I assume he's using hex numbers to identify NetBSD device nodes. I'm not
actually sure this is necessary, though - the howto I found didn't do this.
I think the netbsd port *might* just use the ordering of devices in the
disks= list to identify what device they are, not the VBD id number (I could
be wrong here).
Juergen: this should be doable, I've done it so I know it ought to work. Keep
trying!
Cheers,
Mark
