I have activated HyperV3.0 on windows 2012 server. I made a virtual machine, operating system is windows 2008 R2 SP1. Users connect via remote desktop and use applications. While on the guest server the CPU usage is 60%-80% host CPU usage does not exceed 5%. There are 2 CPUs, total of 8 core CPUs. Virtual machine sometimes experiences slow downs due to CPU usage. Right now I am using 4 VCPUs. How can I allocate more CPU to the guest machine? Does it have anything to do with NUMA settings?
Thank you for your time.
