If you are using the pre-built VPC images for VS 2008 (Orcas), you need to read this

It is a bad deal, and may be very disruptive. But at least knowing ahead of time means you can copy your files off before the VPC stops working.
Note that it stops on NOVEMBER 1 - THIS THURSDAY!!!
On my msdn subscription it looks like they've reposted the VPC images today (10/30/07), there's new ones there. The description for it says:
The Beta 2 VPC images downloaded before October 29, 2007 will expire on November 1, 2007, which is earlier than anticipated. After that time, the VPC will operate for only 1 to 2 hours before needing to be restarted. This restart can be eliminated by upgrading the underlying installation of Windows Server on the original VPC image. Also, these downloads are new VPC images. To transfer Team Foundation Server data to a new VPC, see Moving Team Foundation Server.
