篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了KVM 在 Ubuntu 18.04 Desktop 安装相关的知识,希望对你有一定的参考价值。

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 
# Let NetworkManager manage all devices on this system
network:
  version: 2
  renderer: NetworkManager
  ethernets:
        eno1:
                dhcp4: no
                dhcp6: no

  bridges:
          br0:
                  interfaces: [eno1]
                  dhcp4: no
                  addresses: [192.168.200.5/24]
                  gateway4: 192.168.200.1
                  nameservers:
                          addresses: [192.168.1.1,192.168.200.1]
michael@homeserver:~$ sudo netplan --debug  apply

  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:
