Hi Experts!

I’m having some trouble connecting a newly installed vCenter instance to a newly installed OpenNebula (vOneCloud)

When clicking on “Hosts” and “+” sign and enter the following info;

Type: vCenter  
Hostname: vcenter.domain.local  
User: administrator@vsphere.local  
Pass: XXXXXX

Clicking “Get cluster” lists my cluster without any issues

Markes the cluster and clicking “Import”

Host created successfully. ID: 1

And then my cluster status is ERROR  
Status: error

Information  
ID 1  
Name HPCluster   
Cluster HPCluster   
State ERROR   
IM MAD vcenter   
VM MAD vcenter

vCenter information  
VCENTER\_CCR\_REF domain-c8019   
VCENTER\_HOST vcenter.domain.local   
VCENTER\_INSTANCE\_ID aa4f6b1c-b0dd-4258-9082-5e88206328b5   
VCENTER\_PASSWORD JKCqyHsEESWhItq3/O19How==   
VCENTER\_USER administrator@vsphere.local   
VCENTER\_VERSION 7.0.2.0

No change if I try to “Offline” & “Enable”

Attributes  
ERROR Sun May 2 10:29:30 2021 : Error monitoring Host HPCluster (1): Could not get hosts information - [one.host.info] User couldn’t be authenticated, aborting call.

User & pass is NOT incorrect as I can login to the vCenter without issues with the same user/pass.

My versions:  
OpenNebula 6.0.0.1 (vmware appliance)  
vCenter 7.0 Update2a (7.0.2-17920168)

Any ideas??

This indicates an auth error from the vcenter driver to oned. Please check:

[Known Issues — OpenNebula 6.0.4 documentation](https://docs.opennebula.io/6.0/intro_release_notes/release_notes/known_issues.html#authentication-issue)

It’s been 5 years and your shit still doesn’t work.

The authorization info that your driver is using is not correct. This can be due to a number of factors:

- wrong ONE\_AUTH variable
- wrong placement of one\_auth
- the login token problem introduced by FireEdge, that you can solve following my previous link.

I suggest starting from scratch, 5 years dealing with a misconfigured system is probably too much. OpenNebula 6.2 doesn’t feature the FireEdge login token batch, so you’ll be fine in that regard.

Also, please feel free to [try out vOneCloud](https://docs.opennebula.io/6.2/quick_start/deployment_basics/try_opennebula_on_vmware.html#try-opennebula-on-vmware), which is a sandboxed OVA where all the configuration details have been already taken care of.
