Linux 5.12 Should Be Able To Boot As The Root Partition On Microsoft's Hypervisor
As part of increasing the Linux virtualization support within the Microsoft space, they were working to allow Linux root partition support with the Microsoft hypervisor. The "root partition" with their hypervisor is similar to Xen's Dom0 for in turn starting and managing the unprivileged domains. Linux 5.12 is set to have the Hyper-V code changes to allow the Linux kernel to work as the root partition on Microsoft's Hypervisor.
Sent in Tuesday as part of the Hyper-V patches for Linux 5.12 is that ability for Linux to boot as the root partition. Plus there are a number of other low-level, minor changes but this root partition support is the most interesting. So assuming Linus has no objections with it, the code should be part of the 5.12 stable release this spring.
