I would be suprised if NetBSD/xen could not boot via UEFI but actually all
my xen machines still use BIOS boot (mostly for historical reasons).
We have multiboot2 support, so technically it is unclear to me why xen
would fail.
While I would very much like that to be true, I simply do not understand enough of the boot magic to have an opinion other that ?it seems not to work?.
I have a Xen system booting via EFI (this machine doesn't support BIOS boot):
menu=Boot Xen PV:load /netbsd console=pc root=dk1; multiboot /xen-debug.gz dom0_mem=8192M console=com1,vga com1=115200,8n1 conring_size=4096k sync_console
I tried this, using Xen 4.20 and NetBSD 10.1. Unfortunately the hypervisor crashed instantly. My guess is that this is the same crash as before (although at that time I used Xen 4.18). However, while it was very fast I took a movie and I’ve attached the last useful frame from that movie. I’m sorry about the glare. Does that picture provide any useful clues?
