The Horizon FLEX virtual machine cannot be powered on.

Problem

When you try to power on the Horizon FLEX virtual machine, the operation fails.

Cause

The failure of the Horizon FLEX virtual machine to power on can stem from several causes.

  • The Horizon FLEX virtual machine was created on a Horizon FLEX server version newer than the client version that you are running. As a result, the hardware version of your Horizon FLEX virtual machine is not compatible with the Horizon FLEX server.

  • The Horizon FLEX virtual machine might have been created with more virtual processor cores or a larger memory size than your host system supports.

Procedure

  1. Contact your Horizon FLEX administrator for assistance. For the compatibility problem, your Horizon FLEX administrator can provide the Horizon FLEX client version to upgrade to. You might also be able to solve the compatibility problem by updating or downgrading the hardware version of your Horizon FLEX virtual machine.
  2. Upgrade to the latest Horizon FLEX client version to address the issue of excess virtual processor cores or memory size for the host. Beginning with Horizon FLEX 1.7, the client automatically tries to boot the Horizon FLEX virtual machine with settings based on available resources.
