在一台 Mac Mini mid 2011上安装Ubuntu20.04并配置KVM环境, 过程也适用于其他版本的Mac Mini.
I5 2415, 内存8G*2, 硬盘 SSD 500G + HDD 500G. 1Gbps网口. USB比较寒碜只有2.0, 不过只用于跑服务也不需要挂载移动硬盘, USB慢点没关系.

通过Ubuntu系统的Disk打开U盘, 然后restore disk image, 选中下载的iso
检查是否支持KVM
grep -E -c "vmx|svm" /proc/cpuinfo
# or
more /proc/cpuinfo |grep vmx
more /proc/cpuinfo |grep svm
# or
sudo apt install cpu-checker
kvm-ok
安装KVM
sudo apt install qemu qemu-kvm libvirt-daemon bridge-utils virtinst
如果使用图形界面, 可以加上virt-manager
检查
$ lsmod | grep -i kvm
kvm_intel 282624 0
kvm 663552 1 kvm_intel
检查
# 是否运行
systemctl status libvirtd
# 是否开机自启动
systemctl is-enabled libvirtd
# 虚机列表, 刚安装应该是空的
virsh list
添加用户组(貌似可以不需要)
sudo usermod -aG libvirt $USER
sudo usermod -aG kvm $USER
默认的网卡设置是这样的
more /etc/netplan/00-installer-config.yaml

需要修改为这样格式的设置, 根据自己的网络情况修改

应用
sudo netplan apply
查看温度时, 会发现有些温度不正常, 下面标出的那两个温度94.0°C和98.0°C, 这是因为换的第三方硬盘没有Apple专用的温度检测, 所以温度数字不对.
