Open Stack

Hi All,

I've been working on Nova (stable/essex) with VMWare ESXi as the Hypervisor. Everything working fine except "nova-manage service describe_resource" function. Following snip shows the error:

root at openstack-secondary:~# nova-manage service describe_resource openstack-secondary
Command failed, please check log for more info

And the nova-manage log is like this:

Also I'm getting an error while compute is trying to update its status to the scheduler. The error in compute's log is as show below:

Compute_nodes table is not getting updated because compute is not able to poll scheduler with host details. And "nova-manage service describe_resouce hostname" fetches data from compute_nodes table. Is the problem related to the vmwareapi? Has anyone faced/worked on similar problem?

Any help would be appreciated..:)

Regards,
Sirisha G
