VMWare Virtual Appliance Failed Login

Reading Time: 2 minutes

The VMware Appliance has a web interface and ssh login capability. The old-style Java-based client was phased out after vSphere version 5.5, being replaced by the much more responsive HTML5 application.

VAMI Unable to Login

I encountered a really strange problem today when I could not log in to my vCenter appliance. I know the password and the user account, but I was just getting this error:

Vmware Appliance, VMWare Virtual Appliance Failed Login
unable to log in error

Now I was 100% certain of the password. To confirm I logged into the appliance via SSH with the exact same credentials. As you can see, SSH was working fine. How Wierd!

credentials working fine via SSH

The cause of this error was that the applmgmt service was not running. Here is how to fix it:

Step 1 – Log into your vCenter appliance via SSH

Use your favorite SSH tool such as PUTTY ideally with the root credentials

Step 2 – Check What Services are running on the vCenter Appliance

From the command line, type the following to list the running services:

service-control --status

You will get output similar to this. You are looking for the applmgmt service, see the highlighted text below.

Step 3 – Start the applmgmt Service

To start the service simply type:

service-control --start applmgmt
[email protected] [ /var/log/vmware/applmgmt ]# service-control --start applmgmt
Operation not cancellable. Please wait for it to finish…
Performing start operation on service applmgmt…
