I have a Server 2012 R2 Data Center running Hyper-V. The hardware on the host is 2x 2.6 GHz CPU (28 cores) and 384 GB of RAM. I host 15 virtual machines running Server 2012 R2 STD and Server 2008 R2 (RDS). Right now I give 4-10 cores per VM.
1. Are my VMs under powered? (CPU usage on the host is always 1-8%)
2. Can I give each VM 10 cores each, more than the cores I have?
