in fact, it was vhd and not hvd.
if I understand correctly, guestmount uses qemu to allow the host to access the contents of the virtual machine disk : it makes it live to access its disk ?
thank you for answering.

You can email libguestfs@redhat.com (no need to subscribe).

The instructions for compiling from source are here:

  http://libguestfs.org/guestfs-building.1.html

although libguestfs is included in most Linux distros.

Not sure what an "hvd" image is, but qemu (which we use to access disk
images) supports vhdx, although it may be that writing to vhdx is not
very reliable because it won't be well tested.  I would keep backups
of your disk images while trying it out anyhow.
