1. Re: Cannot complete the operation. See the event log for details - NSX VIBs failed
VijaySendhur Jul 23, 2015 8:39 AM (in response to Sateesh_vCloud)In rare cases the installation of the VIBs succeeded but for some reason one or both of the userworld agents does not functioning correctly
If Message bus service is active on NSX Manager:
P.lease check the messaging bus userworld agent status on hosts by running the command /etc/init.d/vShield-Stateful-Firewall status on the ESXi hosts
It should be running
Check Message bus userworld logs on hosts at /var/log/vsfwd.log
esxcfg-advcfg -g /UserVars/RmqIpAddress
Run this command on the ESXi hosts, it should display the NSX Manager IP address
Run this command on the ESXi hosts to check for active messaging bus connection
esxcli network ip connection list | grep 5671 (Message bus TCP connection)

1. DNS settings in the ESXi host are working fine for the NSX host preparation to succeed.
2. TCP/80 from ESXi to vCenter is not blocked which is required for the host preparation.

ocecil Jul 23, 2015 9:35 AM (in response to Sateesh_vCloud)1 person found this helpfulI had this exact same issue while deploying NSX in my DR site. Check your DNS and make sure it is set up correctly for all your hosts before preparing the hosts. I initially had DNS left blank while I was getting this error, but soon as I configured DNS on ESXi, VIBS were installed correctly.

ShirinKumar Aug 28, 2015 11:27 AM (in response to Sateesh_vCloud)HI,
Can you please check the UWA Agent is working fine and communicating with NSX Controller properly, you can verify it by the below command.
The user world agent (UWA) is composed of the netcpad and vsfwd daemons on the ESXi host. UWA Uses SSL to communicate with NSX Controller on the control plane. UWA Mediates between NSX Controller and the hypervisor kernel modules,except the distributed firewall. Communication related to NSX between the NSX Manager instance or the NSX Controller instances and the ESXi host happen through the UWA. UWA Retrieves information from NSX Manager through the message bus
agent.
we can verify the status of User World agents (UWA) from CLI:
/etc/init.d/netcpad status
From the ESXtop, You can verify the Deamon called netcpa running or not.
Also you can check at the logs of the UWA in the below location
User World Agents (UWA) maintain the logs at /var/log/netcpa.log
Hope you can find something in Netcpa log.

Verify Installation Status of NSX VIBs:
Below are the 3 NSX VIBs that get installed on the ESXi host:
- esx-vxlan
- esx-vsip
- esx-dvfilter-switch-security
Let’s verify that the all the above VIBs are installed using the below command
esxcli software vib get –vibname esx-vxlan
esxcli software vib get –vibname esx-dvfilter-switch-security
esxcli software vib get –vibname esx-vsip
That’s it. We have verified the status of NSX ViBs installation on ESXi hosts. check if any thing is missed out.
Helpful ?

shaefner Oct 6, 2015 6:24 AM (in response to Sateesh_vCloud)The issue here is most likely TCP/80 from vCenter to NSX Manager is not allowed. This is required for the host preparation.
