Microsoft released 20, 000 lines of code to the Linux community. The linux driver was developed by Microsoft’s open source technology center. This is the first time that Microsoft released Linux code to the Linux community. This is going to improve the performance of Linux OS which is virtualized on windows server 2008 Hyper-V or Windows Server 2008 R2 Hyper-V. Without this driver code, Linux can run on top of Windows, but the performance level is not going to be that high. The code is released under GPLv2 license, which is the Linux community’s preferred license.
