Failed to deploy template: The virtual disk is either corrupted or not a supported format
Posted by martijnl on January 22, 2009
Ran into this error when I was at a customer site and found that there is not a lot of information available online. The first post that I found describing the error was on VM/ETC. Have not found a definitive solution yet as I first suspected something had gone wrong with a snapshot on the particular template I was using. Built a new template and did not run into the error for a couple of days.
Then I found these posts (post 1, post 2) on the VMware Forums and have tried the workaround mentioned in this comment as the template and the VM’s to be generated from this template were located on the same LUN.
The error has not turned up since but it stayed away for a couple of days last time.
