Subject: | Re: [Qemu-devel] Simultaneous vhostfds= and ifname= options |

Hi guys,Qemu does not allow currently to use vhostfds= and ifname= options of -netdev tap... at the same time. In order to use vhostfds=, you have to also use fds= instead. May ask you what is rationale behind that?I am asking as we need this for the OpenContrail vRouter multiqueue support. We are passing name of previously created tap, and vhost-net device descriptors (which are supplied by the libvirt).Actually I have internally a very simple patch that allows for simultaneous vhostfds= and ifname=. All seems to work fine with this, but perhaps there is something I do not know and this combination of options indeed should not be allowed.If there is no issues with allowing for that, I could contribute it.Regards,Michal
