Virtual Iron has just launched the Virtual Appliance Exchange over on our forums.

Running a Virtual Appliace on Virtual Iron is very easy:

1. Download a virtual appliance
2. Copy the VHD file into the vdisks directory
3. Open and start the Virtualization Manager
4. Creat a logical volume for the virtual appliace and import the VHD
5. Follow the instructions for the virtual appliance

To get things started, a CentOS 4.4 Virtual Appliance is available.
