Thank you Daniel. How difficult to extend libvirt for this? One critical application on my VM needs to turn vnet_hdr off. I can switch to use qemu directly. However, in that way I will lose all the nice things provided by libvirt. Thanks, ~Jianfeng On 3/3/14 3:53 AM, "Daniel P. Berrange" <berrange@redhat.com> wrote:

Hi,
I am using libvirt and virsh to create my VM on KVM. It works fine. However, I need to turn off vnet_hdr for virtio interface.
Does anyone know how to do it through libvirt?
There's no support for disabling it - if we detect a host which supports it, it will be unconditionally enabled.
