Live Migration in OVM 3.0.2

Question

When I try to live migrate a guest vm, I don't get any target server options; here is the output I'm seeing in the AdminServer.log file:
...<Default CPU Parameters- en: true, threshold: 1.00>
...<Default Net Parameters- net: 2801-HF, en: true, threshold: 1.00>
...<Default Net Parameters- net: 10.2.6.0, en: true, threshold: 1.00>
...<Default Net Parameters- net: 10.2.7.0, en: true, threshold: 1.00>
...<Server: server01.test.com, cpu utilization: 0.88%>
...<Server: server01.test.com, network: 2801-HF, rx mBytes: 0, tx mBytes: 0>
...<Server: server01.test.com, network: 10.2.7.0, rx mBytes: 0, tx mBytes: 0>
...<VM/Server: vm-test/server02.test.com, speed 2666.8, cpus 1, util -1.0%>
However, if I remove the vnic from the guest vm, I am able to live migrate and this is what I see in AdminServer.log:
...<Default CPU Parameters- en: true, threshold: 1.00>
...<Default Net Parameters- net: 2801-HF, en: true, threshold: 1.00>
...<Default Net Parameters- net: 10.2.6.0, en: true, threshold: 1.00>

...<Server/Network server01.test.com/2801-HF: serverNetLimit 38250.0, newServerRx 0, newServerTx 0>

...<Fit map for VM: vm-test, on server: server01.test.com- cpuFit:true, memFit:true, netFit:true, fitFactor:0.931>
I've seen the log throw out compatibility errors when the 2801-HF network wasn't present on each server; however, I've fixed that issue. Since I can live migrate without a VNIC present, I thought it might be another network issue, yet I'm not even seeing "com.oracle.ovm.mgr.business.CompatibilityChecker" being ran when a guest has a VNIC.

Answer 1

Both servers have the same bridge device configured (checked by running ifconfig -a on each server), if that's what you mean being defining a VNIC. While the guest vm is configured with a VNIC, I am able to offline the guest vm, migrate it, and then online it again on the second server without any issues. I was assuming any type of network difference (like a lack of a VNIC being defined on both servers) would have shown up in the AdminServer.log file under the execution of "com.oracle.ovm.mgr.business.CompatibilityChecker".
Thanks for the quick response.
