I currently have two virtualization projects going.  One is to convert 3 physical server to hyper-v and one is to convert 3 physical servers to KVM.  Unfortunately p2v on a domain controller is not only not recommended, it doesn’t work well.  Also there is no supported upgrade path from server foundation to anything but standard.  I have foundation and enterprise.  So I am firing up a new enterprise vm and then will manually mount the vhd from foundation backup to grab the files.  It’ll be a permissions nightmare for a bit but i’m used to that..:)  Once i get my AD domain migrated then it is time for Astaro.  Then i decom two boxes saving myself 200 watts of continuous draw.  The draw goes down to about 60 watts.  Keep watching for the KVM conversion.  That one is going to be easier.
