Hi Greg,
Error: Invalid response from server
>> Ideas? and anyway to get the system to be more perscriptive about the error that just "invalid response" ?
Answer:
You can get more descriptive information from the vCloud Director logs.
SSH to vCD machine
cd $VCLOUD_HOME/logs
#less vcloud-director-info.log
#less vcloud-director-debug.log
Also check the NFS Mount is properly mounted in the vCloud Cell.
