本次使用家庭NAS服务器,IP与MAC绑定,分配其内网地址为192.168.1.88。
0x00 安装cpu-check来查看CPU是否支持虚拟化
sudo apt install cpu-checker
确认支持KVM技术
0x01 安装软件和依赖
sudo apt install qemu qemu-kvm libvirt-bin bridge-utils virt-manager
0x02 修改网络类型为桥接,请注意,这里要将原有的网卡连接删除或注释
修改/etc/network/interfaces
auto lo
iface lo inet loopback
# The primary network interface
# auto enp3s0
# iface enp3s0 inet manual
auto br0
iface br0 inet static
address 192.168.1.88
gateway 192.168.1.1
netmask 255.255.255.0
dns-nameservers 192.168.1.1
bridge_ports enp3s0
bridge_stp off
bridge_fd 0
bridge_maxwait 0
sudo service networking restart
0x03 创建磁盘镜像
qemu-img create -f raw ubuntu.raw 80G
或者
qemu-img create -f qcow2 ubuntu.qcow2 80G
关于这两种虚拟磁盘镜像格式,有一些区别。
0x04 创建启动描述文件 ubuntukvm.xml
<domain type='kvm'>
<name>ubuntukvm</name> //虚拟机名称
<memory>1048576</memory> //最大内存,单位k
<currentMemory>1048576</currentMemory> //可用内存,单位k

其中cdrom在安装完成镜像后需要删除。
