Can you explain why in more detail. We don't expose this as a configurable
setting because we don't believe there's any compelling reason to disable
it. ie it offers clear performance benefits with no downsides.

No special reason. Just in my case I was told to turn off vnet_hdr in order
to make my VM work properly.
I have two choices: extend libvirt or switch to use qemu command.
I asked them to fix it in their product, but it is out of my control and it
did not fit in my timeline.
