Thanks Dominique & Daniel.
Looks like i need to upgrade my VMs kernel to make it aware of virtio.
Found this information from this link:
http://wiki.libvirt.org/page/Virtio#Disk_.28block.29_device_driver
I tried without upgrading the Kernel and as soon as i start my VM it got
into Kernel Panic. I will try using virtio after upgrading my VMs kernel.
As somebody has already said it would have to be a really old kernel to
not handle virtio-block, and it's more likely that your bootloader
and/or initrd are confused by sda becoming vda.
However if your kernel supports it then virtio-scsi should be even
better than virtio-block and shouldn't cause the device name to change.
