KVM使用

这里使用的是Ubuntu18.04桌面版虚拟机

关于KVM可以看一下我之前的博客,有一些简单的介绍。

1.在打开虚拟机之前先开启此虚拟机的虚拟化功能。

KVM使用

2.安装KVM及其依赖项

wy@wy-virtual-machine:~$ sudo apt install qemu qemu-kvm libvirt-bin bridge-utils  virt-manager

3.安装完成后，启用libvirtd服务(默认是开启的)

wy@wy-virtual-machine:~$ sudo service libvirtd start

wy@wy-virtual-machine:~$ sudo update-rc.d libvirtd enable

4.启动之后查看一下libvirtd服务的运行状态

wy@wy-virtual-machine:~$ service libvirtd status
