Server 2012 with Hyper-V
After running Windows Update a couple of days ago, it seems like VM's are running dead slow.
The Hyper-V host seems to be fine thought.
Seems like all kind of VM (W732, W764, W8xx etc.) have the same problem.
It doesn't matter if I use RDP or Hyper-V's own connection, they behave similarly dead-slow.
The VM's do not show high cpu load, nor memory exhaustion.
I have tested a little on another Hyper-V environment (Windows 864 Pro with diverse Win7 and XP VM's), this environment exhibits similar problems (after the same July update, was just fine last week)
I have no clue what is going on, anyone have ?
