From 506bbc8569014253ea8614b680ccbc4fc2513a87 Mon Sep 17 00:00:00 2001 From: Boqun Feng Date: Wed, 13 Oct 2021 11:32:09 +0800 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.
