[Samba] AD DC as KVM guest on file server host?

I would think running both your DC's as VM's would be a good idea -  
makes it easier to backup the VM's in to protect against failure of the 
physical host(s).  Whether or not a DC is physical or virtual, you will 
still have the same client dependency issues.

The thing to avoid would be having the KVM host machine double as 
anything else-  you want to keep the host layer as stable as possible.

I haven't used KVM.  I have used VMware ESXi and Xen, so my observations 
may not apply to KVM.
