Hi,

I'm trying to run a virtual machine in XEN3, which I've installed in NetBSD5.1 
via pkg_add.
The packages were "grub", "xentools3", "xentools3-hvm", "xenkernel3" and my 
package-path is: 
"ftp://ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/i386/5.1_2010Q3/All";

I've managed to boot the XEN3_DOM0 kernel, but when I try to create a virtual 
machine with "xm create -c /usr/pkg/etc/xen/vm/test.cfg" it just tells me the 
following message:
        ...
        mountroot: trying cd9660...
        root file system type: cd9660

I want to install NetBSD5.1 from an .iso file to an empty disk file, which I 
have created with "dd if=/dev/zero of=test.vm bs=1k count=1000000"
I've tried to resolve the problem myself, but I can't get any further.

/usr/pkg/etc/xen/vm/test.cfg:
        kernel = '/xen3_domu.gz'
        memory = 128
        name = "test"
        vcpus = 1
        nics = 1 
        disk = [ 'file:/usr/pkg/etc/xen/vm/test.vm,0x1,w', 
'file:/usr/pkg/etc/xen/isos/netbsd.iso,0x2,r' ]
        root = "xbd1"
        vif=[ 'bridge=bridge0' ]

I hope you understand my problem, English isn't my first language. I'd 
appreciate any help, thanks.
