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

Zabbix can use low-level discovery rules to automatically configuration. • vmware.vm.perfcounter and vmware.hv.perfcounter items were added to allow custom hypervisor and virtual machine performance counter monitoring. A configurable timeout was added to VMware 3.1 VMware monitoring A new vmware.hv.sensor.health.state key has been added to monitor VMware hypervisor health state rollup sensor.
