OpenStack Compute (nova)

nova-compute fails to use vmwareapi drivers

Asked by Nitz

Hi,

I have installed Grizzly on Ubuntu server 12.04. Trying to configure nova-compute to use vmwareapi drivers. The nova-compute service fails to start with either ESX or VC driver. I am having ESXi 5.1.0 (799733) and VC 5.1.0a (880472). Both ESXi & VC have valid license and web access enabled. The sdk is copied on to the compute host in /var/var/lib/tomcat6/webapps/vmware/SDK. I am able to access the wsdl location from any host on the network.
Portgroup with bridge interface br100 is created.

nova.config parameters

compute_driver=vmwareapi.VMwareVCDriver
instance_name_template=instance-%08x
api_paste_config=/etc/nova/api-paste.ini
vmwareapi_host_ip=10.115.200.155
vmwareapi_host_username=root
vmwareapi_host_password=vmware
vmwareapi_cluster_name=osdeploy
vmwareapi_wsdl_loc=http://10.115.200.178:8080/vmware/SDK/vsphere-ws/wsdl/vim25/vimService.wsdl

The same happens for 'vmwareapi.VMwareESXDriver'.
Any guess what could be wrong? Am I missing something?

have you enable ssh access to ESX or Vcenter, you should first ensure ssh is enabled .

Thanks Yaguang for offering help.
SSH access to ESX & vCenter server was already in place.

I couldnot have nova-compute load vmware-api drivers until the security certificates were downloaded on my compute host.

This is what worked for me
- On the compute host download the security certificate from https://<ESX Host IP or vCenter IP>/sdk
- For more info refer vSphereManagementSDKReadme.html available in SDK extracts.
- And for detailed reference use Developers guide at http://pubs.vmware.com/vsphere-51/topic/com.vmware.ICbase/PDF/wssdk_510_dsg.pdf

My compute host is now able to load vmware api drivers (ESX or VC). But im unable to create virtual instance using any vmdk image file. The instance goes through the build stage & ends up with status 'ERROR'. This happens while using vmwareapi. VC drivers.

From the log it looks like it throws an exception in reading 'attr_name'. Not sure what could be causing it?
Any help would be highly appreciated.

Can you try this one,

Configure the values to vCenter details instead of host

vmwareapi_host_ip=10.115.200.155
vmwareapi_host_username=root
vmwareapi_host_password=vmware

Can you help with this problem?
