I'm using libvirt 0.6.2 on F11 x86_64 and CPU supports hw virtualization. When I try to do 'virsh attach-interface ...'

I found it in the man page.



I have a private network declared now, thank you Mark.

And here is how I am trying to attach an interface:
# cat PRIVBR0.xml
 <network>
   <name>PRIVBR0</name>
   <bridge name='privbr0'/>
   <ip address='172.19.0.1' netmask='255.255.0.0'>
   </ip>
 </network>

# virsh net-list --all
Name                 State      Autostart
-----------------------------------------
PRIVBR0              active     yes
default              active     no

# virsh attach-interface CC  bridge privbr0
error: this function is not supported by the hypervisor: device type 'interface' cannot be attached

# grep emulator  CC.xml
   <emulator>/usr/bin/qemu-kvm</emulator>


I tried the 'attach-interface' both while the domain is running and while shutdown. Neither works.

Can anyone see something wrong in what I'm doing here or the reason that 'attach-interface' is failing?

I have also tried this as 'attach-device' with the same result:

# cat INTERFACE_PRIVBR0.xml
   <interface type='bridge'>
     <mac address='00:0c:01:41:50:01'/>
     <source bridge='privbr0'/>
   </interface>

# virsh attach-device CC INTERFACE_PRIVBR0.xml
error: Failed to attach device from INTERFACE_PRIVBR0.xml
error: this function is not supported by the hypervisor: device type 'interface' cannot be attached

I opened the following bug on this issue: https://bugzilla.redhat.com/show_bug.cgi?id=537688
