I`m tring to set up Openstack + ESXi 4.1 system...

Form the begining. Ive prepated server system with Openstack Controller and Compute (KVM) and everything works fine. Now, I want to replace Openstack Compute KVM node with ESXi 4.1 Hypervisor. Ive already installed ESXi and prepared Openstack Controller, but i can`t find way how to install/find/etc nova modules at ESXi system. So, my quastion is: How to get access to nova modules at ESXi and put there nova.conf file?

Deployment of OpenStack on ESX/ESXi slightly differs from that on KVM. The nova modules won't be installed on ESX/ESXi host directly, but on a VM over the same host (recommended) or external server.

For flags, you can refer to readme at http://nova.openstack.org/vmwareapi_readme.html (http://nova.openstack.org/vmwareapi_r...)

For example, I install nova inside my ubuntu VM that runs on the same ESX host. Here is a snippet from nova.conf from the ubuntu VM, where 10.0.120.11 is IP of my ESX host.

---snip---nova.conf file:

--connection_type=vmwareapi --vmwareapi_host_ip=10.0.120.11 --vmwareapi_host_username=root --vmwareapi_host_password=password --vmwareapi_wsdl_loc=http://10.0.120.9:8080/vimService.wsdl

---snip---nova.conf file

Hope that helps

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

Not seen that error.

What version of OpenStack are you working with? Folsom or Essex?

Any chance you can post the stack trace. Sounds like it might be a bug that has crept in, but it should be clearer from the stack trace.
