I wonder if we break management layer. If yes, maybe it's better to keep the
vnet_hdr_support here.
Yes and no, With this series of patches, filters have ability to automatically
Configure the appropriate vnet_hdr_support flag according to the current
environment.
And can report error when can't fixing the vnet_hdr(The user cannot fix it from
the previous way ).
So I think no need for the user to configure this option, some relevant
background knowledge required.
For the management layer, keep the vnet_hdr_support may be meaningless except
for compatibility.
In this situation, Do you think we still need to keep the vnet_hdr_support for
management layer?
So it depends on whether management layer like libvirt has already
supported this. If yes, we may get errors using new qemu with old libvirt?
Thanks
Enable/disable it do the same things for filters.
Thanks
