Virtual Server 2005 R2 - Benefits for Virtual PC today
#1. Virtual Server 2005 R2 is in beta and is probably close to being released. One of the improvements is --speed--.
#2. Check out this entry from Virtual PC Guy from earlier this year.
Microsoft supports having both Virtual PC and Virtual Server installed on the same computer at the same time. When a user does this there are two major 'shared components' between the two products. The virtual machine monitor (VMM.SYS) which is responsible for the basic creation and management of virtual machines, and the virtual machine network services driver (VMNetSrv) which is responsible for providing network connectivity for virtual machines.
One of the interesting side effects of having these shared components is that from time to time one of the components will be updated in one product but not the other. When this happens it is sometimes possible (though not always so) to reap the benefits in both products by having them installed on the same system.
Combine #1 with #2, sprinkle with RAM, and stir. This should be interesting...
...ain't technology grand?
