Following is the stack trace:

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:

Hi Sateesh,

The flags above were all needed for a smooth integration on Nova with ESXi. Thanks for the reply. But right now i'm facing an issue where my compute(configured with ESXi) is not able to poll the scheduler with its usage information. This eventually is not allowing "compute_nodes" DB to be populated. The "nova-manage service describe_resource" function is heavily affected and i'm not able to check the usage details of my compute host. It seems that vmwareapi is not yet built to send the usage data to the scheduler. Have you faced/worked on similar prob?

Regards, Hemanth D

2012-04-20 05:35:53 -0500 answered a question Multi-Zone finally working on ESSEX but cant "nova list" (KeyError: 'uuid') + doubts

Hi,

I'm trying to setup a multi-zone nova setup but have some doubts regarding the same. I've already worked with multi-node(computes) type of setup and was quite successful with it. May i know the configurations that need to be done/changed to setup a multi-zone setup.

I'm trying to setup multi-zone setup on following topology: - 2 nova zones(All components of nova) - 1 Parent Node(API+SCHEDULER+MYSQL+RABBITMQ)

I'm not sure about how can i add the child zones(2 nova zones) to my parent zone.

Appreciate any help on this...!
