Hi Javier.

Thank you for sound advice. Actually, we have a running infrastructure, 
or should I say, we had it. Our original setup was with 2xVMWare + 
1xONE. That worked fine, but we needed live migration feature, so we 
turned to Xen.

We have converted VMDK to RAW and we think we're ready to start playing 
with Xen. One problem that we have, though is the IP. If the IP address 
of the VM is assigned via DHCP and MAC is also randomly assigned, I 
guess there is no way to learn the IP address of the VM, right?

With VMWare we had a way of querying the VMWare server for IP of a 
particular VM, if that VM had VMWare Tools installed.

Now, the link you posted here is something I have visited before. And it 
is the cause of my confusion. In OpenNebula I am supposed to supply 
something like this:

(example from Ubuntu site)

NAME   = Ubuntu
    CPU    = 0.5
    MEMORY = 128
    OS     = [
       kernel   = "/boot/vmlinuz-2.6.18-4-xen-amd64",
       initrd   = "/boot/initrd.img-2.6.18-4-xen-amd64",
       root     = "sda1" ]
    DISK   = [
       source   = "/opt/nebula/images/disk.img",
       target   = "sda1",
       readonly = "no" ]

This would translate in Xen to:

kernel = "/usr/lib/xen/boot/hvmloader"
builder = 'hvm'
memory = 128
name = "Ubuntu"
vcpus = 1
vif = [ 'type=ioemu, bridge=xenbr0' ]
disk = [ 'tap:aio:/home/xen/domains/Ubuntu/Ubuntu.img,ioemu:hda,w', 
'phy:/dev/scd0,ioemu:hdc:cdrom,r' ]
device_model = '/usr/lib/xen/bin/qemu-dm'

And this confuses me. In Xen I can see what I would expect - just the 
path to the DISK to boot from and nothing more. The kernel is 
"hvmloader", just as I would expect.. In OpenNebula there are references 
to "kernel" being a normal Linux kernel and "initrd". These look more 
like boot parameters for GRUB or LILO, then something passed to the Xen 

And then I have to ask what should be in there for Windows?
