UCS Director provisioning fails, “The computer restarted unexpectedly” message shows in VMWare Console

This is one of those “no kidding” moments when you find out what went wrong, but it can be incredibly frustrating when it happens. Check out this screenshot I took when recently trying out a new Server 2012 R2 template:

UnexpectedRestart

“The computer restarted unexpectedly or encountered an unexpected error. Windows installation cannot proceed. To install Windows, click “OK” to restart the computer, and then restart the installation.”

I also got another error about the unattended file not being right, but I didn’t grab the exact error.

It turns out that this was a result of using the same Standard Catalog item to test a 2008R2 template earlier:

ModifyCatalog

 

I had changed the template, but not the Windows License Pool. The result was that UCS Director was trying to use a 2008 key for a 2012 installation….which naturally won’t work well.
