[Bug 1314674] [NEW] Unable to connect to VCenter 5.5 VimFaultException: Server raised fault: 'Element tag ns0:RetrieveServiceContent uses an undefined namespace prefix ns0

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

I'm currently trying to integrate an OpenStack testbed (based on
Icehouse nova-2014.1 , Ubuntu 14.04 standard packages) with VCenter. I
configured nova.conf http://docs.openstack.org/trunk/config-
reference/content/vmware.html:

compute_driver=vmwareapi.VMwareVCDriver

reserved_host_memory_mb=0

[vmware]
host_ip=192.168.0.146
host_username=root
host_password=<password_here>
cluster_name=VCOS
datastore_regex=qnap*

Using the password I'm able to login to VCenter using vSphere Web
Client, Cluster VCOS was created using DRS, and I also defined a port
group br-int on the ESXi hosts in the cluster. Although OpenStack Nova
using KVM works like a breeze on two other compute nodes, I constantly
get error messages on the node running VMwareVCDriver in note-
compute.log

...to me it seems like there is some problem with the SOAP message...
ns0 is not defined as a namespace und <SOAP-ENV:Envelope>?

I also tried a fresh install of the VCenter Appliance 5.1 and 5.5
without any luck. From the error message names above I cannot see any
configuration etc. I might have missed?
