Microsoft Continues Working On Hyper-V Dom0 Support For Linux

Microsoft Linux engineers have continued preparing the Linux kernel to support Hyper-V Dom0 for Linux to run as the root partition.

An initial set of Linux Hyper-V patches were posted last week for preparing to work toward this Dom0 "root partition" support with Linux under Microsoft's virtualization stack.

Nuno Das Neves of Microsoft posted the initial patches that for kicking off the effort are restructuring the Hyper-V header files.

"To support Hyper-V Dom0 (aka Linux as root partition), many new definitions are required.

The plan going forward is to directly import headers from Hyper-V. This is a more maintainable way to import definitions rather than via the TLFS doc. This patch series introduces new headers (hvhdk.h, hvgdk.h, etc, see patch #3) directly derived from Hyper-V code."

Further Hyper-V Dom0 patches are still pending. Given the popularity (and dominance) of Linux in the Azure cloud and other virtualization use-cases, Microsoft continues contributing a lot to the Linux kernel around their Hyper-V support.
