Hyper-V 3.0 Guest Start up Delays
Posted on 2014-02-21
I have upgraded two HP DL380 G5 servers using fresh full installations of Windows Server 2012 R2 with Hyper-V Role
Everything seems to be working like it was with Windows Server 2008 R2 but when I start up new Hyper-V guests they progress quickly to 10% then frequently stall for very long periods (20 to 100 seconds) before continuing to load and run normally
I have never observed such delays when using the same hardware and guests (Windows 7, 2008 R2, 2012 R2, 2003 R2) running under Windows 2008 R2 so what is different and can these delays be reduced?
