Microsoft's great Hyper-V has completely screwed me again. I have a 2008 R2 virtual machine and I was running 4 VM's. I just got a new server and installed 2012 R2 and moved all the VM's over. This one VM in particular (which is running 2008 R2 and Exchange 2013 Standard) would not start the Exchange Transport service on the new server. So I tried deleting the NIC from the VM when it was on the original server and shutting it down and THEN moving it to the new server (export feature apparently doesn't work going from 2008 to 2012...thanks MS for letting us all know that BEFORE we purchase your over priced software). And now either the new server or old I am completely screwed, I can log into the VM but pretty much after that it's a horrible SLOW performance. So slow that when I immediately try to right click on Network and go to Properties it just hangs. I've tried adding a new NIC to the VM, I've tried deleting the NIC from the VM and starting up with no NIC. The problem may be Exchange, but how do I fix it? I can't believe Hyper-V is THIS friggin unstable!!!!
