Subject: [PATCH] virt: Support detection for ARM64 Hyper-V guests
|
||
|
|
|
||
|
|
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[1], then use DMI tables to
|
||
|
|
detect a Hyper-V guest, which is more generic and works for ARM64.
