I have couple of CPUs that don't support Virtualization Technology natively.
Will I see any improvements in PPD if I switch from Windows SMP to Linux via VMware?
CPU must have VT to benefit from running VMware?

afaik you can't run 64bit OS in vmware if your CPU doesn't support VT, and the linux SMP client only works on 64 bit linux. I've ran into this with my laptop, only way to run linux SMP client is with native linux I'm afraid.

Re: CPU must have VT to benefit from running VMware?
I don't know if the old X2 4400+ supports some kind of visualization technology, but I run a Linux 64 on XP 32 fine, and performances are good. I also run Linux64 on XP32 on a Q6600. I use VMWare Workstation 6.5 on both machines.
P.S : VM are limited to two CPUs (I don't know any VM software that allows access to more than two physical CPUs), so you have to run two VM on a quad core ... that's starting to use a huge amount of memory (Linux SMP A2 WU are big, and 1 GB of RAM is a minimum to allow).

Re: CPU must have VT to benefit from running VMware?
It doesnt matter if you have xp/vista 32/64 bit or whatever, but if your CPU doesn't support VT (which is VIRTUALIZATION technology, not visualisation) you CAN'T run any 64bit OS inside vmware. This mostly concerns laptop CPUs, as most of desktop CPUs support VT. It also depends on the motherboard manufacturer if it has built in support for it in its bios.toTOW wrote:I don't know if the old X2 4400+ supports some kind of visualization technology, but I run a Linux 64 on XP 32 fine, and performances are good.

Which is quite complicated is that there are at least 4 level of VT : none, basic, Intel VT/AMD-V and Intel EPT/AMD RVI ... and it's pretty hard to find exactly what each CPU supports.

Intel's VT and AMD-V is practically the same. All Nehalems should support EPT. And RVI is something a bit different.toTOW wrote: Which is quite complicated is that there are at least 4 level of VT : none, basic, Intel VT/AMD-V and Intel EPT/AMD RVI ... and it's pretty hard to find exactly what each CPU supports.
Re: CPU must have VT to benefit from running VMware?
That's interesting. Do the X2's support some sort of VT that the intel e5xxx don't? Because when I ran VMware Player, it could only operate in 32bit mode. Perhaps there's a bios setting?toTOW wrote:I don't know if the old X2 4400+ supports some kind of visualization technology, but I run a Linux 64 on XP 32 fine, and performances are good.

Re: CPU must have VT to benefit from running VMware?
No idea how applicable my experience would be to an AMD, but when I went to run VMWare utilizing my processor, I had to enable Intel's VT through the bios as it wasn't on by default.
