I am running two HP workstations (Z400: 4-core Xeon processor; Z600: 2x4-core Xeon processor) equipped with Win 7 Pro x64. The guests are in both cases 32bit Win XP Pro. Both computers have 16 GB RAM and Nvidia Quadro 2000 or 4600 cards.
I don't know the proper virtualization settings (Preferred mode; Disable acceleration for binary translation; Virtualize Intel VT-x/EPT; Virtualize CPUperformance counters).
Any input will be greatly appreciated.
