You can securely connect to a vCenter Server from App Volumes using an SSL certificate.


Ensure that the vCenter Server you are connecting to has a domain SSL certificate.

The certificate must be verified and accepted by App Volumes.


  1. From the App Volumes Manager console, click Machine Managers > Add Machine Manager.
  2. Enter the required Machine Manager information and click Save.




    Enter vCenter Server

    Host name

    The host name of the Machine Manager. For example, server.your-domain.local

    User name

    The user name with which you will access the machine. For example, YOURDOMAIN\administrator.


    The password for the user name.

    Mount Local

    Select this option if your VM's datastore has local copies of volumes and you want to mount the local copies.

    Mount on Host

    Select this option if you want to connect directly to the VM host. This results in increased performance and decreases the burden on the vCenter Server.

  3. Verify the certificate details.

    If the certificate is not trusted or verified, the following messages are seen:

    • A window with details of the certificate (SHA1 fingerprint, period of validity) that is present in the vCenter Server.

    • A message at the top right corner:

      Server error: SSL certificate is not verified and needs to be accepted to continue.
  4. Click Accept to accept the certificate.

    You can also log in to the vCenter Server as an administrator and verify the SHA1 code.

    The Machine Manager is successfully added after the certificate is verified.

  5. Click Certificate to view the certificate you added.

    If the certificate is changed on the vCenter Server after it has established a connection with App Volumes Manager, the Certificate not valid message is displayed when you log in to App Volumes Manager.


    You also see this message when you upgrade App Volumes to the latest version.

  6. To validate the certificate again, select the vCenter Server under Machine Managers, click Certificate, and accept the certificate.


You now have a trusted SSL certificate to connect to the vCenter Server.

What to do next

When you upgrade App Volumes from an older version to the latest version, verify the connectivity of each machine manager. You might have to manually accept the certificate to retain the connection to vCenter Server.
