Hello, I seem to be experiencing major issues with Hyper-V on Windows Server 2012. Basically, when I try to add a resource and/or change virtual machine settings in Hyper-V it takes an extremely long time... 30+ minutes to make the change. After a really long time, the state of the virtual machine changes to Off-Critical. This affects other virtual machines on the same box.
This is a new install of Windows Server 2012 with all updates applied. I've also had the same thing happen when no updates were applied.
According to resource monitor, nothing is being pegged. Disk also looks good. CPU is under 5%. Memory is under 10%. I have no idea what the heck is going on. The only thing that I can think of is that I have recently installed new 128 GB of RAM in this box. The memory is obviously compatible as I wouldn't be able to boot otherwise.
I have three 3TB SATA disks in Parity mode used to stored all virtual hard disk files.
Any suggestions would be greatly appreciated.
