Re: reaching the guest from the host through network

[Emmanuel Touzery <etouzery gmail com>]

just a point of reference, i tried really hard to make this work first with boxes then with virt-manager, and with virt-manager i gave some links on the gnome bug where it looks some people made it.

but otherwise now i gave up because unfortunately setting up the guest and accessing it is only step one, i have many more things to do. and so I set up virtualbox and there it's point-and-click and i can tell you 100%, virtualbox can bridge vlan interfaces without any problems with the latest fedora18 3.7 kernel. and without root, too. maybe there was a one-time setup as root and then of course they have a kernel driver i believe, but now i'm running it as normal user.

Thats what I thought too but seems libvirt guys do not agree:

<zeenix> http://wiki.libvirt.org/page/Networking#Bridged_networking_.28aka_.22shared_physical_device.22.29
<zeenix> " Unfortunately, wireless interfaces cannot be attached to a
Linux host bridge"
<zeenix> is that really true?
<zeenix> i clearly remember doing that with success
<zeenix> that doc seem a bit outdated. Talks of disabling network
manager for fedora 12
<danpb> that is still accurate - you can't use bridges with wifi in
general, because most wifi cards will refuse to send packets with
different MAC addrs
<danpb> and of course traffic from VMs will have different mac addrs
