qemu-kvm创建虚拟机

创建桥接

编辑/etc/network/interface

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet manual

auto br0
iface br0 inet static
  address 192.168.50.199
  netmask 255.255.255.0
  gateway 192.168.50.1
  dns-nameservers 114.114.114.114
  bridge_ports eth0
  bridge_stp off
  bridge_waitport 0
  bridge_fd 0

创建虚拟磁盘

qemu-img create -f qcow2 ubuntu_base.img 20G

安装系统

kvm -m 1024 -drive file=ubuntu_base.img,if=virtio -cdrom /root/ubuntu-14.04.3-server-amd64.iso --nographic -vnc :0

windows安装virtio驱动

kvm -m -1024 -drive file=windows.img,if=virtio \
-cdrom windows7.iso \
-drive file=virtio-win-iso,index=3,media=cdrom \
--nographics -vnc:0

创建xml文件

用xml文件启动虚拟机

virsh create ubuntu_base.xml
