<div text="#000000" bgcolor="#FFFFFF"> Hi Jon, <br>
<br>
Thanks for the feedback. I don't believe its an issue
with libvirtd versions, but with the utilities managing
libvirt. Opennebula can already use the openvswitch
bridges when defined in a VM xml configuration file. <br>
<br>
Upon inspection of the attach_nic script, we can see there
that it's using "virsh attach-inteface" while attach_disk
uses "virsh attach-device" and uses an xml config file as
input. The virsh utility does not support openvswitch
bridges when specified in the command line yet. <br>
<br>
I'm seeing how we can device a workaround for this. Either
we re-program the attach_nic script to use "attach-device"
or encapsulate the ovs bridge as a libvirt network
definition as suggested in the libvirt-users list. <br>

<br>
Hope everyone is doing ok. :)<br>
<br>
Just want to ask if anybody has tried the NIC
hot plug functionality<br>
with OpenVSwitch. I'm testing ONE 4.0.1 and
am having error messages<br>
pertaining to the creation of the virtual
ports for the VMs. It<br>
outputs "error: Unable to add bridge ovsbr0
port vnetX: Operation not<br>
supported". I did some Google'ing and it seems
that the virsh CLI<br>
utility has not been updated to support
OpenVSwitch bridges as it still<br>
treats the type bridge argument to be a linux
bridge. I'm thinking of<br>
recoding the "attach_nic" script to create an
xml file and use "virsh<br>
attach-device" to hot plug the NIC the same
way disk hot plugging is<br>
done. Any thoughts? Or is there something
else I should know why ONE<br>
used "attach-interface" in the first place?<br>
<br>
Thanks,<br>
John Robert Mendoza<br>
