测试环境

查看是否支持KVM

参考：

对于aarch64（arm64）架构,若支持KVM虚拟化，那么KVM代码会直接编译进内核

2020年3月，Linux 5.7 Kernel宣布将放弃支持 32位架构的 KVM虚拟化支持，所以目前来看，要想较好的在ARM架构上运行KVM虚拟化，需要使用现代化的64位ARM架构

# 如果/dev/kvm和/sys/module/kvm二者之一不存在说明KVM虚拟化是不支持的
ls -l /dev/kvm
ls -l /sys/module/kvm

cat /boot/config-`uname -r` | grep VIRTUAL
CONFIG_VIRTUALIZATION=y
# CONFIG_GKI_HIDDEN_VIRTUAL_CONFIGS is not set
# CONFIG_REGULATOR_VIRTUAL_CONSUMER is not set
CONFIG_FB_VIRTUAL=y

在arm64上启动qemu虚拟机有两种方式，一种是通过-kernel 的方式boot kernel，另一种是先启动uefi再boot kernel。

QEMU默认将会采用seabios的启动方式
