License about Host and Guest OS

Hi all,

I'm new to Virutal PC. What is the license scheme about host and guest in
following cases?

Current stage
XP prof (host) + XP prof (3 guests)

Migration from XP to Win 7
Win 7 (host) + XP prof (3 guests)
Win 7 (host) + Win 7 (1 guest) + XP prof (2 guests)
Win 7 (host) + Win 7 (2 guests) + XP prof (1 guest)

Complete stage
Win 7 (host) + Win 7 (3 guests)

Thanks
Cko

The same rules apply in all cases. Each OS installed in a vm needs it own
license.

When you have 3 Win 7 vms running on a Win 7 host you need 4 Win 7
licenses.

The only exception I am aware of is the XP version available with XP Mode
in Win 7.

In the current stage you need four licenses for XP Pro. Each guest requires
its own. After you upgrade to Win7 on the host (Win7 Pro or above) you can
take advantage of one Virtual XP vm for one license and then you would only
need one Win7 and two XP Pro licenses for "> Win 7 (host) + XP prof (3
guests)."

Why are you "migrating" the guests? If you have the Win7 licenses why not
just install Win7 guests after you have "migrated" on the host? By
"migration" do you mean upgrade? A migration suggests a clean install
followed by installation of applications and migration of user profiles and
data. What you are doing sounds more like upgrades.
