Exchange 2010 High Availability on DC

I need to setup an Exchange 2010 infrastructure. I am limited to just two servers. Each server will also
act as a DC for the domain. Is it possible to setup any kind of High availability solutions for Exchange using this
setup? Can I use Hyper-V to setup DAG and CAS array? Any suggestions will be greatly appreciated.

First of all, it is not recommended to have Exchange on a DC.
It would be ideal,if you can get two beefy servers and run Exchange and DCs as VMs on it. It should have good spec as well.

Best bet will be to run Exchange 2010 on both servers with all three roles and have a hardware load balancer (Cheap ones from Kemp Technologies).

And then have a DC running on a cheaper server. You won't have resilience on DC in that case.
one solution with hyperV:
2 physical servers  = 2 hyperV hosts ( without any HA )

on each hyperV: you can create 3 VMs: one DC, one CAS/HUB et one MBX
physical Host 1
VM1-1 : 1st DC AD
VM1-2 : Exchange 2010 CAS/HUB with NLB, 1st node for NLB
VM1-3 : Exchange 2010 Mailbox DAG, 1st member of DAG

physical Host 2
VM2-1 : 2nd DC AD
VM2-2 : Exchange 2010 CAS/HUB with NLB, 2nd node for NLB
VM2-3 : Exchange 2010 Mailbox DAG, 2nd member of DAG

one drawback: hyperV servers must be members of the AD domain hosted in the Virtualized DCs , not very cool !!

what if I have Active directory on the physical servers and Exchange roles on Hyper-V. Isn't  this a better solution that having AD on Hyper-V?
