I have one question related with OpenStack vmwareapi.VMwareVCDriver resize/cold migration.<br><br></div>
The following is my configuration:<br><br clear="all"><div><div><div><div><div><div>
DC</div><div>
|</div><div>
|----Cluster1</div><div>
| |</div><div>
| |----9.111.249.56</div><div>

|----Cluster2</div><div>

|----9.111.249.49</div><br></div><div><b><u>Scenario 1:</u></b><br></div><div>I started two nova computes manage the two clusters:<br></div><div>1) nova-compute1.conf<br>
cluster_name=Cluster1<br><br></div><div>2) nova-compute2.conf</div><div>cluster_name=Cluster2<br><br></div><div>3) Start up two nova computes on host1 and host2 separately<br></div><div>4) Create one VM instance and the VM instance was booted on Cluster2 node 9.111.249.49<br>
| OS-EXT-SRV-ATTR:host | host2 |<br>
| OS-EXT-SRV-ATTR:hypervisor_hostname | domain-c16(Cluster2) |<br></div><div>5) Cold migrate the VM instance<br></div><div>6) After migration finished, the VM goes to VERIFY_RESIZE status, and "nova show" indicates that the VM now located on host1:Cluster1<br>
| OS-EXT-SRV-ATTR:host | host1 |<br>
| OS-EXT-SRV-ATTR:hypervisor_hostname | domain-c12(Cluster1) |<br></div><div>7) But from vSphere client, it indicates the the VM was still running on Cluster2<br></div><div>8) Try to confirm the resize, confirm will be failed. The root cause is that nova compute on host2 has no knowledge of domain-c12(Cluster1)
