Configuring HVM

[Andreas Gustafsson <gson%gson.org@localhost>]

I tried to boot a NetBSD-current/amd64 installation ISO that
successfully boots in PV mode, using a NetBSD-current dom0, Xen 4.11,
and the following configuration file which is closely based on the one
Greg A. Woods posted:

name = "freebsd"
uuid = "46118b1d-53fb-11e9-ba99-d4ae528b9511"
type = "hvm"
memory = 1000
maxmem = 4000
vcpus = 4
boot = "d"
#vif = [ 'bridge=bridge0' ]
disk = [
        'format=raw, vdev=hda, access=rw, target=/root/work-http---mirror.araneus.fi-local-2019.04.07.17.46.49-release-amd64-+a4/wd0.img',
        'format=raw, vdev=hdd, access=ro, devtype=cdrom, target=/root/work-http---mirror.araneus.fi-local-2019.04.07.17.46.49-release-amd64-+a4/install_tmp.iso'
]
serial = "pty"

That failed to boot, saying:

(d9) ata0 master: QEMU HARDDISK ATA-7 Hard-Disk (2048 MBytes)
(d9) ata1  slave: QEMU DVD-ROM ATAPI-4 CD-Rom/DVD-Rom
(d9) 
(d9) 
(d9) 
(d9) Press F12 for boot menu.
(d9) 
(d9) Booting from CD-Rom...
(d9) 357MB medium detected
(d9) CDROM boot failure code : 0004
(d9) Boot from CD-Rom failed: could not read the boot disk
(d9) 
(d9) 
(d9) No bootable device.
(d9) Powering off in 30 seconds.

Any clues?
