I installed Windows server standard 2012 with Hyper V role on a box running an Asus Sabertooth Tz77 with an intel I7 3770 running at 3.5 ghz and a realtek gigabit network card and 16 gig of Ram.
Windows on the host load fast and work fine until I start to create the virtual machines and fire it up. First VM is a domain controller running windows 2012 standard and I assign 4 gig of ram. Second one is running SQL 2005 and it has 4 gig of ram assign. And the 3th one has IIS with an application that run under Asp 2.0 sp1.
When all those VM are on everything goes sloooooow on all the VM.
One at the time is Ok but not all 3.
I run the exact same VM on a server before with less ram and processor power than this one. The only diference was that it was under win 2008 hyper V not 2012.
What can be different on 2012 that slow it down so much?
