VMware vSphere ESXi
Issue/Introduction
- You may experience this is if an ESXi was recently disconnected from vCenter inventory recently and on reconnect, when trying to power on VMs following error may be seen:
"All required agent virtual machines are not currently deployed on host 'hostname'" in seen in the UI."
- You have NSX configured in the environment and may be running Horizon VMs
- If you navigate to Administration > vSphere Client Extensions > VMware ESX Agent Manager > Configure in vCenter Server, we see "Warning" or "Alert" for the status of the NSX extension
- When you access NSX UI, you can see it is in a "disconnected" state from vCenter Server
- You try to reconfigure and add in NSX account password to complete this, error like below may be seen indicating password expiring of the account:
Environment
vCenter Server 8.x
ESXi 8.x
NSX
Cause
Due to NSX being in a disconnected state with vCenter, the extension for NSX is not connected/operating as expected and VMs are unable to be powered on
This may occur due to an expired service account password causing NSX to be in a disconnected state
Resolution
To resolve the issue please update the NSX account password through vCenter UI and reconfigure the connection.
- Navigate to the user account in vCenter Server under Administrator -> Groups and Users -> selecting domain --> select to edit user with expired password
- Update the password here for the account and save the changes
- Navigate to NSX UI and select to edit configuration
- Provide the updated password here and select to save changes
In NSX, we should now see that connection is re-established
This should sync quickly with vCenter and VMs should be powering on without further error
