Re: Xen root filesystem on disk with gpt partitions

maybe with GRUB2?  here is a non-xen sample with casual "gptX" partition number.

menuentry "netbsd" {
        insmod ufs2
        set root=(hd0,gpt2)
        knetbsd /netbsd -v
}

apparently --root=wd0e is optional, works without it for GPT.

once that works, you can switch to XEN with something like that (draft).

menuentry "XEN" {
        insmod ufs2
        set root=(hd0,gpt2)
	multiboot /xen.gz loglvl=info guest_loglvl=info noreboot=true smt=1 ept=exec-sp com1=115200,8n1 console=com1,vga
	module /netbsd bootdev=... ro console=...
}

If you also want to enable serial console, I noticed on GNU/Linux that the console= argument still needs to be dom0's hvc0 and not ttyS0 for it to work.  Serial port seems to remains under control of the hypervisor.  Not sure how it goes for NetBSD dom0.
