From: Yongkui Guo Date: Mon, 30 Jan 2023 10:20:32 +0000 (+0800) Subject: Add support for Alibaba cloud on aarch64 X-Git-Tag: v1.26~12 X-Git-Url: http://git.annexia.org/?a=commitdiff_plain;h=805604762468b754ea60e5dc176fa26f68d211b8;p=virt-what.git Add support for Alibaba cloud on aarch64 This assumes you are running RHEL or another tenant which supports ACPI. It probably won't work for guests using device tree. Also we assume that the hypervisor is KVM. Since the hypervisor indicates that it is RHEL 7, this is very likely to be true, but hard to prove since there is no CPUID on Arm.
