Hi guys,

My company is writing and maintaining the current OpenStack Nova Hyper-V =
driver.  We are also working on a CloudStack Hyper-V driver, I'd be glad =
to contribute the code that we have and our experience with Hyper-V. =
Unfortunately due to our commitment on OpenStack, we didn't manage to =
finish it yet, but I'd be very glad if we could join your efforts on =
that.

If possible, we would also be happy to contribute our OpenStack Python =
code referenced in this thread.

My IRC nick on Freenode is alexpilotti in case you'd like to have a talk =
about it.


Thanks,

Alessandro Pilotti
