Microsoft Hyper-V Support Further Improved With Linux 6.18

([Microsoft] 5 Hours Ago Hyper-V)


Microsoft's Hyper-V virtualization support within the Linux kernel continues to be steadily enhanced and it's inched along further for [1]Linux 6.18 .

The Microsoft Hyper-V code for Linux 6.18 has now unified its guest entry code for both KVM and Microsoft Hyper-V (MSHV).

A new feature for Hyper-V users is Linux 6.18 now supporting Kexec and Kdump from Azure Confidential VMs (CVMs). The necessary integration is now in place for properly handling Kexec / Kdump in that confidential compute environment.

Microsoft has also now formally deprecated its Hyper-V frame-buffer "hyperv_fb" driver in favor of the Hyper-V Direct Rendering Manager (DRM) driver. This is no real surprise and arguably overdue. DRM/KMS drivers are far better than the Linux FB drivers that have been steadily but slowing being phased out.

Plus there are a variety of other Hyper-V changes with Linux 6.18 as outlined in [2]this pull and already merged to mainline.

If for every rule there is an exception, then we have established that there
is an exception to every rule. If we accept "For every rule there is an
exception" as a rule, then we must concede that there may not be an exception
after all, since the rule states that there is always the possibility of
exception, and if we follow it to its logical end we must agree that there
can be an exception to the rule that for every rule there is an exception.
