首先要在bios中开启Intel-vt,KVM 的代码都并入Kernel了，所以安装也比较简单。
michael@homeserver:~$ sudo apt update michael@homeserver:~$ sudo apt install qemu qemu-kvm libvirt-bin bridge-utils virt-manager michael@homeserver:~$ service libvirtd start michael@homeserver:~$ update-rc.d libvirtd enable
配置Bridge 是难点默认是NAT，这样你就很难访问机器里的资源了, Ubuntu desktop 使用的是NetworkManager,我感觉它不是特别好用，卸载完NetworkMananger想换回原始的system-networkd 导致最终非常复杂，网都连不上了。系统也没有东西，为了省时。重装系统使用Netplan配置。
michael@homeserver:~$ cat /etc/netplan/01-network-manager-all.yaml

不知道为什么，重启服务没有什么用，我最终重启了机器。

安装Windows 10 的时候，发觉有两个鼠标，并且非常难控制。有人提了一句启动的时候加入，-usb -usbdevice tablet。 KVM并不是太懂，所以又查了查，有老外给了个解决方法，最终解决。
The equivalent for that is to open up the virtual machine details > Add Hardware > Input > EvTouch USB Graphics Tablet
目标的homeoffice 环境如下：
