Hi Kamil and your team,

Really great that you’ve decided to work on a hypervisor for dfly. Thank you :D

I confirm that my bounty offer is available.

Your email below is quite complete and you’ve already answered my questions on IRC. I have minor comments, FYI.

Personally, I’d like we have the same Intel and AMD CPUs support as in NetBSD. Besides, I have an AMD 3700X, so I’d like to run NVMM on my box :P

DragonFly hasn’t used pkgsrc for a long time, so I don’t know whether it would be easier to just use DPorts.

DragonFly BSD itself should on the supported guest OS.
