If it is really a virtual disk conversion problem, Mayuresh, I would try
to convert it with VBoxManage instead of qemu-img, or the other way
around.  Both support RAW, QCOW2 and VDI.  Depending on the conversions,
the one works better than the other.

You can indeed check whether the conversion was successful by checking
the geometry of the disk image.  You can also further mount a partition
from it with a Gnu/Linux system with losetup, partprobe, eventually
partx, and ntfs-3g.

If everything is fine, it is rather about the drivers:

1. check what possibilities you have to change the device type presented
to the HVM guest.  I do RAW on Blktap2 with `tap:tapdisk:aio` but I
think just `file:` does the same nowadays.  Maybe there is an alternative.

2. try to install the GPLPV drivers before the conversion --
