My desktop has AMD 8-core CPU (3.2GHz) and 32GB RAM, I installed Windows Server Datacenter 2012 onto VMWare workstation 10.0.4, I assigned 4 vCPU, 16GB RAM and 120GB HDD to this virtual server, in the "Virtual Machine Settings", Hardware---> Processors, My "Preferred mode" is "Automatic", I also selected both "Virtualization Intel VT-x/EPT r AMD-V/RVI" and "virtualization CPU performance counters".
the issue I have is the installation of any VMs are extremely slow, try to install windows XP Professional (I use old OS because they are relatively less bloated, it will take 2h to finish, and I tried Ubuntu 8.0 and Centos 4.8 (I know both are not supported by Microsodt due to competing relations), it will takes forever, so I gave up. Also when I use anything related to HyperV, it is very sluggish.
I am setting this in my home lab, and my server's Windows 2012 trial license expired, so I can only play with HyperV inside VMWare workstation. I also installed ESXi 5.5 in a similar way, it works smooths without much hiccup.
Any solutions? thanks!
