You can display a list of the machines whose operation VMware Horizon 8 has detected as being suspect.

Horizon Console displays machines that exhibit the following problems:

  • Are powered on, but which are not responding.
  • Remain in the provisioning state for a long time.
  • Are ready, but which report that they are not accepting connections.
  • Appear to be missing from a vCenter Server.
  • Have active logins on the console, logins by users who are not entitled, or logins not made from a Connection Server instance.

Procedure

  1. In Horizon Console, select Inventory > Machines.
  2. On the vCenter tab, click Problem Machines from the Machines drop-down menu.

What to do next

The action that you should take depends on the problem that Horizon Console reports for a machine.

  • If a machine is powered on, but does not respond, restart its virtual machine. If the machine still does not respond, verify that the version of the Horizon Agent is supported for the machine operating system. You can use the vdmadmin command with the -A option to display the Horizon Agent version. For more information, see the Horizon 8 Administration document.
  • If a machine remains in the provisioning state for a long time, delete its virtual machine, and clone it again. Verify that there is sufficient disk space to provision the machine.
  • If a machine reports that it is ready, but does not accept connections, check the firewall configuration to make sure that the display protocol is not blocked.
  • If a machine appears to be missing from a vCenter Server, verify whether its virtual machine is configured on the expected vCenter Server, or if it has been moved to another vCenter Server.
  • If a machine has an active login, but this is not on the console, the session must be remote. If you cannot contact the logged-in users, you might need to restart the virtual machine to forcibly log out the users.
