can not start domU as HVM

[Victor Gamov <vitspec%gmail.com@localhost>]

Hi All!

I trying to install HVM guests (NetBSD and FreeBSD) on NetBSD-XEN but
still without success.

My configuration:
AMD Opteron 2214 on MSI K9NU motherboard
NetBSD-5.0.1 installed
also installed:
xenkernel33-3.3.1nb1
xentools33-3.3.1nb6

XEN started but strange message appears in `xm dmesg`:
(XEN) Xen heap: 14MB (14480kB)
(XEN) Domain heap initialised

# xm list

Then I'll try to start NetBSD as HVM guest from following config:
------------------ cut here -----------------------
kernel = "/usr/pkg/lib/xen/boot/hvmloader"
builder='hvm'
memory = 256
name = "netbsd1"
vif = [ 'mac=00:16:3e:00:00:13, bridge=bridge0, type=ioemu' ]
device_model = '/usr/pkg/libexec/qemu-dm'
disk = [ 'file:/var/xen/netbsd1,ioemu:hda,w',
'file:/var/xen/amd64cd-5.0.1.iso,ioemu:hdd:cdrom,r' ]
boot='d'
vnc = 1
usb = 1
------------------ /cut here -----------------------

# xm create -c netbsd1.xen

Following lines appears at /var/log/xenbackendd.log:
------------------ cut here -----------------------

------------------ /cut here -----------------------



So, my questions are:
-- is it possible to start HVM (FreeBSD or NetBSD) guest on this
hardware and software?
-- where I'm wrong ?


Thanks!
