Ok, so after my first day yesterday after a rather long vacation I today wanted to look at the problem that the Administrator password isn’t changed when using VirtulCenter’s clone customization functionality (which relies at least for Windows on sysprep).
After a short googling, I stumbled upon this.
Simple problem short … Don’t specify an Administrator password for the template. Then you should be able to change the Administrator password when cloning the template. It’s “should“, as the VM’s are still updating.
And it really works. After emptying the Administator password, the cloning works just fine. Damn sysprep bug …
