Q: Can I use P2V on a source that is not domain joined?  I need this for DMZ machines and acquisitions.

Q: What is "offline" P2V?
A: On-line P2V uses snapshots to capture the data on the drives to acheive an application-level consistent conversion.  However, this requires that the application is VSS framework-aware. Off-line P2V copies a customized image of WinPE 2.0 to the physical system and reboots to it, then the data from the disks are transferred to the target Virtual Server and put in .vhd format. The matrix of what OS’s support on-line and off-line p2v as at . The way I think of the difference is that online P2V is a good choice for cloning a machine, and may require you to monitor and fix up any issues if you have applications running that might modify data during the conversion. Offline P2V is a good choice for migrating a machine, and usually won't have any issues for you to fix up, since there are no apps running during the conversion.
