Recent XEN3_DOM0 begaviour
I recently restored my earlier NetBSD/XEN setup on an old(ish) HP
EliteBook laptop; it all went rather well using xen packages for 4.11.
I then added a couple of disks to the system (one - the internal
mSATA, the other - on the tray replacing the DVD) with the intention
to use the second one as storage for XEN guests. I formatted this one
as GPT and added a couple of disks:
# gpt show wd1

/dev/rwd1: 2 wedges:

name = "okn"
kernel = "/netbsd-XEN3_DOMU-amd64-bar.gz"
vcpus = 2
memory = 2048
vif = [ 'mac=aa:bc:0e:d1:0e:09,bridge=bridge0' ]
disk = [ 'phy:/dev/dk1,0x1,w', 'phy:/dev/dk0,0x2,w' ]
It all works well, with the exception that when I reboot the host
under XEN using the usual
menu=Xen:load /netbsd-XEN3_DOM0.gz console=pc;multiboot /xen.gz dom0_mem=2048M
the kernel decides that it has been booted from dk0, instead of wd0,
and I have to be present for the boot and point wd0 to be the boot
disk (BTW if I point at this moment to dk1/dk0 I am able to boot the
guest on bare metal using the same XEN3_DOM0 kernel... ).
Is there any means to force XEN3_DOMU to use wd0 as boot device? This
doesn't happen if I use the normal /netbsd kernel, it can see dk0/dk1
but proceeds to booot from wd0 by default.
Or perhaps I have to modify XEN3_DOM0 ?
