The following table lists some of the differences between the online and ofﬂine P2V conversions.
Requirements on the Source Machine:
To perform a PZV conversion, your source computer: Must have at least 512 MB of RAM.
Cannot have any volumes larger than 2040GB. Must have an Advanced Conﬁguration and Power Interface (ACPI) BIOS Vista WinPE will not install on a non-ACPI BIOS.
Must be accessible by VMM and by the host computer. Cannot be in a perimeter network. A perimeter network, which is also known as a screened subnet, is a collection of devices and subnets placed between an intranet and the lntemet to help protect the intranet from unauthorized lntemet users. The source computer for a P2V conversion can be in any other network topology in which the VMM server can connect to the source machine to temporarily install an agent and can make Windows Management Instrumentation (VVMI) calls to the source computer.
