[THIN] Re: VMWare

Ya sure but the fact is that ESX does not use the Linux kernel as it's virtualization engine. ESX != Linux. It uses a modified Linux VM for the management interface. Simple as that.

If it wasn't for the Apple II or TRS 80 or Commodore 64 or whatever then none of this would be possible :)

    ESX will always have better performance because the VMkernel (not linux
    kernel) has full control to manage all hardware resources and doesn't
    have to pass request through an OS layer (like GSX).

    Single proc is definitely the way to go on almost all VMs. I'm still
    puzzled at the reasoning behind announcing 4-way SMP, esp since it will
    benefit maybe %1 of VMs.
