What --virt-type should I use with virt-install?

  • 772

When I look at "man virt-install" for Fedora 13 I see

  --virt-type
    The hypervisor to install on. Example choices are kvm, qemu, xen, or kqemu.
    Availabile options are listed via 'virsh capabilities'
    in the <domain> tags.

But which should I use for which guest OS?

My host is a Fedora 13 with KVM.

virtualization linux redhat kvm-virtualization

    I would suggest you use "--virt-type qemu", especially that since qemu 0.10.0 it now uses KVM if available.

    If this does not work try "--virt-type kvm".

    Qemu, KVM, KQemu are all virtualizers.

    Qemu used to provide software virtualization only (comparable to an emulator in some sort), but now (since Qemu 0.10.0) also provides hardware virtualization through KVM (using the AMD-V and VT-x features of nowadays processors) if it is available and installed.

    As said above KVM provides hardware virtualization (it uses a feature that can be found in recent/new processors).

    KQemu was a fork of Qemu providing both software and hardware virtualization using KVM. It has been integrated directly into Qemu in version 0.10.0.
