<div class="moz-cite-prefix"><small>Hi Sudeep , <br>
<br>
I deal with windows machines in ONE day by day (unfortunately).<br>
<br>
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.<br>
<br>
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 y</small><small>ou
eventually be able to boot it.<br>
<br>
then if you want to convert it (the window machine) to use
virtio bus, you can do the following:<br>
<br>
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),<br>
<br>
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<br>
<br>
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: <a
href="http://www.linux-kvm.org/page/WindowsGuestDrivers/Download_Drivers">http://www.linux-kvm.org/page/WindowsGuestDrivers/Download_Drivers</a>
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.<br>
<br>
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:<br>
DISK=[AIO="native",CACHE="none",DEV_PREFIX="vd",IMAGE_ID="yy"]<br>
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)<br>
DISK=[AIO="native",CACHE="default",DEV_PREFIX="vd",IMAGE_ID="yy"]<br>
i usually get best results with these 2 configs for images of
the "best OS out there"<br style="color: rgb(0, 0, 0);

<br>
5- instatiate it again... boom virtio storage will boot.<br>
<br>
<br>
hope it helps.<br>

<div>Dear Mateusz & All,<br>

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

Dear Mateusz,<br>
<br>
Thanks for replying. Is the below command
correct?<br>
<br>
[root@front ~]# virt-install --connect
qemu:///system --name win7<br>
--ram 1024 --vcpus 2 --disk<br>
path=/var/lib/libvirt/images/win7.qcow2,size=7,format=qcow2,bus=virtio,cache=none<br>

--os-variant=win7 -noautoconsole --accelerate
--noapic --keymap=en-us<br>

try to add target=hda, for example:<br>
<br>
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<br>
<br>
If You are using virtio then drivers for this bus
will be needed, so You need add floppy drive with
drivers.
