nova-compute cannot restart when vmware vcenter confguration.

 

Hi,

I'm evaluating Openstack/VMware configuration now.
I have 2 phisical machine for the evaluation.
I build openstack with ESXi & vCenter like following.

* Openstack controller(Grizzly) phisical machine
* vmware ESXi server phisical machine
  * ClusterA
    * vmware vCenter server VM
        This VM is created by ESXi.
    * openstack nova-compute VM for vCenter VM
        This VM is created by vCenter.
and..
    * instance-0000000a
        This VM is created from glance image.

In the 1st time, this system is running.
And I could create instance from vmdk image on glance using dashboard.

But I rebooted nova-compute VM, nova-compute service was not started.
The compute.log is following.

2013-05-20 13:30:34.847 ERROR nova.compute.manager

vCenter Server Appliance found in the hypervisor, but not in the database
2013-05-20 13:30:34.849 3161 CRITICAL nova [-] 1

To be sure, these VMs are NOT managed by Opentack.
But..what I can do?
Shuld I get more phsical machine for vCenter & nova-compute cluster?
Could someone tell me about this?

Thanks.
nito.
