是的,对于I家的U,跑64位guest os硬件虚拟化是必须
貌似A记的不是,不过没有验证过
对于这个问题VMWARE其实写的蛮清楚了的. 对于AMD同样有要求, 早先的步进是不可以用的.

AMD
Segmentation support is missing from the initial AMD64 processors(that is, revision C and earlier) while running in long mode. As aresult, AMD64 processors prior to revision D do not have anefficient mechanism for isolating the virtual machine monitor from64-bit guest operating systems.
A limited form of segmentation was reintroduced in long mode, inrevision D AMD64 processors. As a result, AMD64 processors must berevision D or later to run 64-bit guest operating systems.
Note: Because AMD Opteron and Turion processors do notship in revision D, AMD Opteron and Turion 64 processors must berevision E or later to run 64-bit guest operating systems.
Intel
Intel CPUs require EM64T and VT support in the chip and in theBIOS.
Intel EM64T CPUs do not have segmentation support in longmode. If the Intel EM64T CPU is VT-capable, it comes with hardwarevirtualization support (Intel's Vanderpool Technology). Thishardware virtualization support allows Workstation and VMwareServer to work around the lack of segmentation, making it possibleto run 64-bit guest operating systems on Intel EM64T VT-capableCPUs.
Note: Firmware/BIOS support is required toenable Intel Virtualization Technology. Some systems (particularlylaptops) do not have the necessary firmware/BIOS support to enableIntel Virtualization Technology, and cannot run 64-bit guestoperating systems. |
