I am trying to deploy New VM from Cent OS 6 template, But customization of guest OS option is not getting enabled on vSphere 4.1. can pls tell me how to do it , or any other way to customise the Guest OS (like change in hostname etc)
Did you figure this out?
I got the same, "centos64guest not supported".
If I change the OS in vSphere to be Red Hat 6 x64, it works fine.. so I guess that's the workaround
Thank you Christopher
