[libvirt] Bridged network (shared physical device) and libvirt
Hi, Are there any plans to include possibility to configure bridged networks in libvirt? I see the need to be able to actually be able create vlans on physical devices and the bridge the vlan, which I guess is a very normal case for isolating network traffic between different guests. I would be great if it would be possible to both create vlans on physical devices and then also create bridged network connected to any available network (physical/bonded/vlan) /Henrik

This is functionality we are actually missing for ovirt as well. I had done a proof of concept patch a while ago (you can search the libvirt archives), but it wasn't comprehensive enough. In particular, it could deal with putting a physical device into a bridge, but didn't make any provision for bonding and VLANs, both of which are needed to have a correct solution. It needs some thought about the XML design, and then it can probably be implemented. -- Chris Lalancette

I see this stuff as system configuration and, as such, should be handled by e.g. NetworkManager: http://bugzilla.gnome.org/show_bug.cgi?id=543232 Cheers, Mark.

There's no reason why libvirt network mgmt APIs couldn't call out to NetworkManager in the background as their impl. In addition if we ever want to have network management in libvirt which works on existing OS deployed to then we'll need an impl that uses initscripts for config. Finally if we ever get a VMWare driver, then we'd want to invoke their APIs for bridge configuration in that context. So there's value in having network mgmt APIs in libvirt. Oh and network manager doesn't provide any remote RPC capabilities Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|
