Hi Michael,
As described above, I create a ovs-based cluster, and added a Host,
and created a VM successfully.
I click the ‘Sync All Networks’ Tab, and “ovs-vsctl show” can get some
seems correct result as follows: (The port ‘p3p1’ is my physical NIC, my vdsm
server have 3 physical NICs, the other two NICs was disabled by me)
ovs-vsctl show
931582d5-9318-48c6-a1d6-8ec486582eb8
Bridge vdsmbr_vfMUcNKp
Port vdsmbr_vfMUcNKp
Interface vdsmbr_vfMUcNKp
type: internal
Port ovirtmgmt
Interface ovirtmgmt
type: internal
Port "p3p1"
Interface "p3p1"
ovs_version: "2.5.0"
At the same time ‘brctl show’ can still get ovirtmgmt information. And then,
the network can not work from vdsm using the Ip binding to p3p1 or ovirtmgmt;
I enable one of the other two NICs and the network is still not work for new
enabled NIC.
I have to reboot the vdsm. After reboot, the vdsm was not abled controlled by
ovirt engine anymore.
Here is some information: (The bridge name in virsh and ovs are not the same,
why? Is this cause the error?)

I can’t find anything about VM because ‘virsh list --all’ show nothing.

I think I already got mad now. ^_^

Thank you
Hi ,
Did you synced network/s after you moved the host to the ovs type cluster?
It seems like you didn't..)
Go to 'Hosts' main tab' and choose the host, go to 'Network Interfaces' sub tab
and press the 'Sync All Networks' , now the networks should be synced to host
as ovs switch type.
Run the vm and check the xml.
It should look something like this:
<source bridge='vdsmbr_nRL3asDq'/>
<virtualport type='openvswitch'>
thanks

I create a cluster which already enabled ovs network as you mentioned , but
when I create vm in this cluster, I can only using ovirtmgmt/ovirtmgmt vNIC
profile, which is still a Linux bridge.
I found no way to add a OVS vNIC profile, I have to chose ovirtmgmt/ovirtmgmt
vNIC to setup a VM. After VM is started, the vm is still using Linux bridge to
communicate with outside, not the ovs.
Need I to create a ovs bridge or vport and bind it to physical NIC in vdsm
manually?
Hope your reply as soon as possible.
Thank you

Please note and note well: OVS is not production-grade yet. It is only a
preliminary tech preview, under active development.
However, we'd be very happy to get your help in testing it (and possibly
fixing it, too).
When defining a new cluster, you should see a check box, letting you
select OVS for that cluster.
To be precise, this is not a check box. In the Edit Cluster dialog, look at the
"switch
type" option, and change "LEGACY" to "OVS".
After being checked, each VM network that
is defined in your cluster would be implemented with OVS instead of
Linux bridge.
As aluded before, there are plenty of known definciencies (e.g., no
persistence of ip config on VM network, no live migration, not all bond
modes, etc etc). But do not hesitate to raise other issues with the
devel mailing list.
Happy testing!
Dan.
