The problem
An error appears when you try and deploy a VMware template following an upgrade of VMware and/or vCenter
“Customization of the guest operating system ‘rhel5_64Guest’ is not supported in this configuration. Microsoft Vista (TM) and Linux guests with Logical Volume Manager are supported only for recent ESX host and VMware Tools versions.”
The Resolution
- Turn the VM Template back into a Virtual Machine
- Power On
- Install VMware Tools
- Check no additional hardware has been changed. Sometimes changing the SCSI controller from LSI Parallel to LSI SAS can cause issues on Linux machines
- Power Off machine
- Convert the VM back to a template
