3 LKML : akataria@vmware.com : Paravirtualization on VMware's Platform [VMI]. : :17:08:JST Hi, We ran a few experiments to compare performance of VMware's paravirtualization technique (VMI) and hardware MMU technologies (HWMMU) on VMware's hypervisor. Please note that specjbb is the worst case benchmark for hwmmu, due to the higher TLB miss latency, so it's a good result that the worst case benchmark has a degradation of only 1%. VMware expects that these hardware virtualization features will be ubiquitous by Apart from the performance benefit, VMI was important for Linux on VMware's platform, from timekeeping point of view, but with the tickless kernels and TSC improvements that were done for the mainline tree, we think VMI has outlived those requirements too. In light of these results and availability of such hardware, we have decided to stop supporting VMI in our future products. 6 vsphere4 monitor modes Table 1: Default monitor modes on Intel processors Virtual Machine Core i7 45nm Core2 65nm Core2 65nm Core2 Configuration with VT-x with VT-x and with VT-x FlexPriority and No FlexPriority FT enabled VT-x + swmmu VT-x + swmmu VT-x + swmmu VT-x + swmmu 64-bit Guests VT-x + EPT VT-x + swmmu VT-x + swmmu VT-x + swmmu VMI enabled(**) BT + swmmu BT + swmmu BT + swmmu BT + swmmu OpenServer UnixWare VT-x + EPT VT-x + swmmu VT-x + swmmu VT-x + swmmu OS/2 VT-x + EPT VT-x + swmmu VT-x + swmmu VT-x + swmmu 32-bit Linux VT-x + EPT VT-x + swmmu BT + swmmu (*) BT + swmmu (*) 32-bit FreeBSD 32-bit Windows: VT-x + EPT VT-x + swmmu VT-x + swmmu BT + swmmu (*) XP, Vista, Server 2003, Server 2008 Windows 2000, NT, 95, 98, DOS, Netware, 32-bit Solaris BT + swmmu (*) BT + swmmu (*) BT + swmmu (*) BT + swmmu (*) Other 32-bit Guests VT-x + EPT VT-x + swmmu VT-x + swmmu VT-x + swmmu 4p (*) When BT is used on an Intel system with VT-x capability, it dynamically switches to 7 3
