Bug description:
[Impact]
* The detection of Microsoft Hyper-V VMs is done by cpuid currently,
however there is no cpuid on ARM64. And since ARM64 is now a supported
architecture for Microsoft Hyper-V guests[0], then introduce a more
generic way to detect whether a guest is running as a Hyper-V guest: check
if /sys/class/dmi/id/product_version starts with "Hyper-V".
* This bug has already been fixed upstream[1][2]
[Test Plan]
* While changes have been made in the kernel for ARM64 on Hyper-V,
there is no way to start an ARM64 VM on Hyper-V at the moment. Thus we
just want to make sure no regression is introduced.
* start an Hyper-V amd64 VM and make sure "systemd-detect-virt" still
return MSFT (should still rely on cpuid here)
[Where problems could occur]
* The main risk is for the system to detect Hyper-V virt erroneously.
An issue was reported upstream after the first commit was merged[3].
For this reason, systemd is now looking for "Hyper-V" (in
/sys/class/dmi/id/product_version) and not "Microsoft" (in
/sys/class/dmi/id/bios_vendor)
* This change might also break virt detection on hyper-v AMD64.
That's why we need testing. However, AMD64 virt detection should still
rely on cpuid instead of DMI as cpuid takes priority over DMI.
