Thank you, that answers my questions pretty thoroughly :) >I believe there is an OVS compatibility module that makes the ioctl used >to connect a tap device to a host bridge also work for OVS bridges. You >may want to look into that. <snip> Br-compat module was removed from OVS few releases ago, IIRC, since libvirt and KVM/QEMU can use Openvswitch bridges natively now. And it works just fine, just not for my use case :) Thanks again for the information on inner workings of user session, now I know what I have to do. Luckily, I don't have that much domains to migrate.
