I have a Windows server box that I need to P2V. I need to save that image to a disk cause that same box is where I will be putting ESXI 5. I am have tried the P2V converter and it works great to a live ESX box, but I have not been able to get it to save to a disk sucessfully. What options do I need to choose to save it to a disk as a vmdk and then import it once I install ESXI?
You can select the destination to be a VMware Workstation image. This will allow you to save the converted server as a set of files. You could then run Converter again, and import these flat files to the ESXi host.
Make sure you have a good backup of the physical server also, in case something goes bad....
