Re: [ovirt-devel] Service vdsmd can't get start again and The bridge name in virsh and ovs are not the same after click 'Sync All Networks' on the vdsm

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?) Ifconfig ovirtmgmt: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.0.117 netmask 255.255.255.0 broadcast 0.0.0.0 inet6 fe80::f8e5:c3ff:fe74:5c59 prefixlen 64 scopeid 0x20<link> ether fa:e5:c3:74:5c:59 txqueuelen 0 (Ethernet) RX packets 8389 bytes 1528498 (1.4 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 22 bytes 3740 (3.6 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 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" vi /etc/libvirt/qemu/networks/vdsm-ovirtmgmt.xml <network> <name>vdsm-ovirtmgmt</name> <uuid>09e92e82-2510-450e-bff7-72252e37b1b8</uuid> <forward mode='bridge'/> <bridge name='ovirtmgmt'/> </network> I can’t find anything about VM because ‘virsh list --all’ show nothing.

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 On Tue, Aug 2, 2016 at 9:37 AM, Meni Yakove <myakove(a)redhat.com&gt; wrote: On Tue, Aug 2, 2016 at 7:12 AM, lifuqiong <lifuqiong(a)cncloudsec.com&gt; wrote: 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?

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. _______________________________________________ Devel mailing list Devel(a)ovirt.org http://lists.ovirt.org/mailman/listinfo/devel -- Michael Burman RedHat Israel, RHEV-M QE Network Team Mobile: 054-5355725 IRC: mburman
