kvm with paravirtualization support

  • 772

I am preparing to verify KVM with paravirtualization support(mainly for networking).

Does mentioning driver name as vhost is enough to make it run in paravirtualization mode ? I have all options relevant to paravirtualization enabled as part of kernel configuration.

Do I need to insmod any other module apart from kvm.ko and kvm_intel.ko ?

Also, do I need to mention any kernel parameters as part of loading these modules(kvm.ko kvm-intel.ko) ?

qemu-system-x86_64 version 1.4.2

Thanks.

Referring this link : http://www.linux-kvm.org/page/Virtio It seems no special drivers is needed at host side. <

    virtio_net is kvm's equivalent of paravirtualization for networking. You might get even better results, especially in terms of latency, if you use SRIOV or VMFEX, but you need special hardware for that.
