    Freeware hypervisors which do not require SLAT support


    There are still many LGA775 computers in use; their Core2 Duo/Quad processors support VT-x but not SLAT/EPT which is required by several current free hypervisors. For reference, here is a list of recent versions which can run on hardware without SLAT support:

    Vmware Workstation Player: 12.5.9 (not supported anymore but working without problems)
    Vmware ESXi: 6.5 (end of support November 15, 2021)
    Oracle Virtualbox: SLAT still is not a requirement in current version 6.1.10
    Microsoft Hyper-V Server: 2012 R2 (end of support January 10, 2023)
    ...corrected, see post below.

    Other ones can be added.

    Reason of correction:
    The Hyper-V - Wikipedia article says "Second Level Address Translation (in Windows Server 2012 and later)" as requirement so initially I tested & recommended version 2008 R2 only. However, the statement is wrong. As you can see, Hyper-V Server 2012 R2 is still fully functional on non-SLAT hardware (whereas Hyper-V Server 2016 isn't).

    Some of these very old CPU's will work with VM's using KVM/QEMU

    Other non-recommended x86 CPUs

    The following CPUs models are compatible with most AMD and Intel x86 hosts, but their usage is discouraged, as they expose a very limited featureset, which prevents guests having optimal performance.

    kvm32
    kvm64
    Common KVM processor (32 & 64 bit variants). Legacy models just for historical compatibility with ancient QEMU versions.
    486
    athlon
    phenom
    coreduo
    core2duo
    n270
    pentium
    pentium2
    pentium3


    Also Pentium IV (works fine on a Sony VAIO old laptop I have with Pentium IV processor).

    Cheers
