VM Import now supports Windows Server 2003 R2 in addition to existing support for Windows Server 2008 (DataCenter, Standard and Enterprise Editions). In addition, VM Import now supports the VHD image format, which is compatible with the Citrix Xen and Microsoft Hyper-V virtualization platforms. With these new capabilities, we have made it even easier for enterprises to leverage their existing investments in operating systems within Amazon EC2. VM Import is available at no additional charge beyond standard usage charges for Amazon EC2 and Amazon S3.
