Hi Sudeep ,
I deal with windows machines in ONE day by day (unfortunately).
what I can see here (a part from the raw-qcow issue) is that it seems
you never installed virtio-drivers (and devices) and you're trying to
boot using virtio bus.
if you haven't installed in the OS (windows) the "Red Hat Virtio SCSI
controller" (see VirtIO drivers) you will have no luck in using virtio
bus.. don't use bus=virtio, use standard emulated IDE ( in the template
a plain IMAGE=[ID="whatever"] ) and you eventually be able to boot it.
then if you want to convert it (the window machine) to use virtio bus,
you can do the following:
1- attach a second image as virtio device (like this:
IMAGE=[ID="xx",DEV_PREVIX="vd"] being "xx" any non persistent image in
your datastore eg: a cdrom image),
2- boot it (keeping your main image in IDE emulation without virtio,
like IMAGE=[ID="yy"] where "yy" is your vbox converted image of Win's
C: drive
3- install the newly found "unknown device" with the divers of Red Hat
Virtio SCSI controller from the binaries relative to your win edition in
the iso here:
http://www.linux-kvm.org/page/WindowsGuestDrivers/Download_Drivers as
suggested by Valentin (he's a smart guy, follow his suggestions ;) in
this way you will tell windows that it's now on "virtio-steroids" that
is: it will eventually boot from a virtio device 'cause now the
controller drivers are enabled at boot.
4- then you can shutdown vm, modify template removing the "xx" cdrom
image you put to install the virtio controller and edit the main image
(c: drive) with a string like this:
DISK=[AIO="native",CACHE="none",DEV_PREFIX="vd",IMAGE_ID="yy"]
if you find awkard slowliness try to enable default cache for
virtio and see if you get it any better (windows really sucks anyway..
be at peace with it)
DISK=[AIO="native",CACHE="default",DEV_PREFIX="vd",IMAGE_ID="yy"]
i usually get best results with these 2 configs for images of the "best
OS out there"
5- instatiate it again... boom virtio storage will boot.
hope it helps.
cheers

Dear Mateusz & All,
I tried a lot but looks like I am not able to figure out.
Again the VM says "No bootable device" gpxe searching for bootdisk
from HDD/Floppy/DVD-CD" etc.
But it is running fine from frontend mode "virt-viewer -c
qemu:///system myvm3"
I tried to virtually mount the iso in the CD drive but that too did
not help.
I have also tried the interactive setup: virt-install --prompt -->
that too does not work when I instantiate in OpenNebula VM.
I have also tried to write the template in Advanced Tab in OpenNebula
following [1] but I am failing.

Hello Mateusz,
I have given now 17G for win7 OS.
On adding target=hda * hdb, it throws the below error.
[root@front images]# virt-install --connect qemu:///system --name
win7 --ram 1024 --vcpus 2 --disk
path=/var/lib/libvirt/images/win7.qcow2,size=17,format=qcow2,bus=virtio,cache=none,target=hda
--cdrom /home/Windows-7-x86.iso,target=hdb --vnc --os-type=windows
--os-variant=win7 -noautoconsole --accelerate --noapic --keymap=en-us
ERROR Unknown options ['target']

Dear Mateusz,
Thanks for replying. Is the below command correct?
[root@front ~]# virt-install --connect qemu:///system
--name win7
--ram 1024 --vcpus 2 --disk
path=/var/lib/libvirt/images/win7.qcow2,size=7,format=qcow2,bus=virtio,cache=none
--cdrom /home/Windows-7-x86.iso --vnc --os-type=windows
--os-variant=win7 -noautoconsole --accelerate --noapic
--keymap=en-us
try to add target=hda, for example:
virt-install --connect qemu:///system --name win7 --ram 1024
--vcpus 2 --disk
path=/var/lib/libvirt/images/win7.qcow2,size=7,format=qcow2,bus=virtio,cache=none,target=hda
--cdrom /home/Windows-7-x86.iso,target=hdb --vnc
--os-type=windows --os-variant=win7 -noautoconsole
--accelerate --noapic --keymap=en-us
If You are using virtio then drivers for this bus will be
needed, so You need add floppy drive with drivers.
The win7.qcow2 image is prepared under
/var/lib/libvirt/images folder
[root@front images ~]# qemu-img create -f qcow2 -o
preallocation=metadata /var/lib/libvirt/images/win7.qcow2 7G
Only 7G for win7 os device?
Or how do I tweak it?

Sudeep
