VPE手动安装说明 - 《controller》

前提，ubuntu虚机支持嵌套虚拟化

以下命令结果为Y
cat /sys/module/kvm_intel/parameters/nested
执行以下命令有输出
grep -E '(vmx|svm)' /proc/cpuinfo

配置DNS，安装软**件包时需要解析DNS**

修改文件
vim  /etc/resolvconf/resolv.conf.d/base
添加内容
nameserver 114.114.114.114
执行更新
resolvconf -u
查看结果
cat /etc/resolv.conf

配置软件源，这里使用清华源

备份原始源文件sources.list
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
更改文件权限使其可编辑
sudo chmod 777 /etc/apt/sources.list
打开文件进行编辑
sudo vim /etc/apt/sources.list
删除原来的文件内容，复制下面内容到其中并保存
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse
deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse

deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse

更新软件列表，换源完成
sudo apt update

安装软件包，网桥管理、虚拟化相关包

sudo apt-get -y install qemu-kvm
sudo apt-get -y install ubuntu-vm-builder
sudo apt-get -y install bridge-utils
sudo apt-get -y install virt-manager
sudo apt-get -y install virt-viewer
sudo apt-get -y install libvirt-bin
sudo apt-get -y install qemu

配置网桥，根据VPE接口数量配置网桥 ``` 修改接口文件 vim /etc/network/interfaces 为物理口配置网桥，如下，拟为VPE配置三个接口，则配置三个网桥 auto ens160 auto br0 iface br0 inet static address 172.171.15.21 network 172.171.0.0 netmask 255.255.240.0 broadcast 172.171.15.255 gateway 172.171.0.1 dns-nameservers 223.5.5.5 bridge_ports ens160 bridge_stp off

auto ens192 auto br1 iface br1 inet static address 10.1.1.2 network 10.1.1.0 netmask 255.255.255.0 broadcast 10.1.1.255 gateway 10.1.1.1 dns-nameservers 223.5.5.5 bridge_ports ens192 bridge_stp off

auto ens224 auto br2 iface br2 inet static address 20.1.1.2 network 20.1.1.0 netmask 255.255.255.0 broadcast 20.1.1.255 gateway 20.1.1.1 dns-nameservers 223.5.5.5 bridge_ports ens224 bridge_stp off


5. **启动virt-manager**

virt-manager 如果virt-manager出现方形乱码，需要先安装字体 sudo apt install fonts-arphic-ukai sudo apt install ttf-wqy-zenhei xfonts-wqy ttf-wqy-microhei ```
