Microsoft to make Viridian Hypercall API widely available
eWeek | at | by Mike
Microsoft will make the hypercall API in Windows Server virtualization available under its Open Specification Promise when the product is released to manufacturing late next year.
This means that the API can be used without licensing fees and with Microsoft's guarantee that it will not sue for violation of its patented intellectual property.
However, for customers who want early access to the interface, Microsoft has posted an updated draft of the hypercall API to its Web site.
