I have a Windows 2008 R2 Cluster with 4 nodes running Hyper-V. Each host is a Dell R710 dual quad-core 2.4 xeon CPUs with 32 GB, hard disk is a Dell EqualLogic PS6000
Each node runs about 5-6 VMs, mostly Server 2003 R2 and each VM perform at approximately the same level that they did as physical boxes using dual 2.4Ghz CPUs and 2-4Gb of RAM.
When I create a Server 2008 R2 VM, I'm experiencing severe lag both through RDP and console access to the guest. I've tried tweaking the Processor type and count and giving the VM 4GB of RAM, but it doesn't make a difference.
Performance Monitor doesn't show high usage of CPU, Memory or Disk that would give a reason for this behavior. Are their recommended settings for running 2008 R2 in Hyper-V?
Any help is appreciated.
