Hi all,
I deployed a new Windows box and installed Converter 5.0.1 onto it and it's P2V-ing my CentOs server ok so far 
I noticed that 5.0.1 configures the VM with hardware v7 whereas 5.1.0 configures it with hardware v9, so perhaps this is the problem? As soon as the conversion's finished I'm going to re-run the job on 5.1.0 and select hardware v7 and will let you know how it goes.
George.
