Thanks for share this informations, unfortunately I'm using Hyper-v 6.1
running Linux, I take a look about Hyper-v paravirtualization kernel for
Linux and drivers for hypervisor and it is a very big concern.
Thanks for paper, I will try to do some workaround for this environment and
report the result.
