What is the status of Hyper-V drivers?
Environment
- Red Hat Enterprise Linux (RHEL)
- Microsoft Hyper-V virtualization hypervisor
Issue
- Microsoft released drivers for Linux to improve performance for virtual Linux hosts running on Hyper-V (Content from www.microsoft.com is not included.press release).
Has this code made it into the supported kernel yet?
Resolution
These drivers bring various improvements to the Linux on Hyper-V experience, but they are not required to run Linux virtual machines on Hyper-V. They have not made it into the Red Hat supported kernel yet.
Microsoft has provided a code drop of their para-virtualization drivers to the Linux kernel community, and this code was added to the "staging" tree in the upstream Linux kernel. As discussed under Content from git.kernel.org is not included.Documentation/development-process, the "staging" tree contains drivers that may be on their way towards inclusion in the regular kernel, but that are not currently up to Linux kernel coding or quality standards. As of November 2011, core parts of these drivers were being moved out of the "staging" tree into the regular kernel, at which point they became candidates for addition to the Red Hat Enterprise Linux kernel.
Customers that are interested in seeing these drivers added to the RHEL kernel are encouraged to contact their Red Hat Global Support Services representative and to provide details on their business case for this feature.
