Whereas a “bare-metal” or “type 1” hypervisor would run directly on the hardware, VirtualBox running Windows XP Service Pack 2) and therefore contain a num- ber of identical RAM cells. The hypervisor can look for such duplicate data in memory, eliminate the redundancy (deduplication) and thereby additional performance improvement of up to 5% can be obtained by enabling this setting. This causes the hypervisor to use large pages to reduce TLB use and overhead. • --vtxvpid on|off: If hardware virtualization
