更新3 另一种更为简单的方式（缺点是：局域网其他机器无法访问该虚拟机）
宿主需要有samba/配置好samba的用户名和共享目录
smb.conf
[share]
path=/home/work/Myproj/vms/share_dir
public=no
guest ok=yes
writable=yes
browseable=yes
valid users=samba1
宿主机操作
sudo useradd samba1
sudo passwd samba1
sudo smbpasswd -a samba1
测试下：
smbclient //127.0.0.1/share -U samba1%123
虚拟机启动脚本
qemu-system-x86_64 --enable-kvm -m 2048 -smp 2 -hda vm1.raw \
-netdev user,id=ndev.0,hostfwd=tcp::5555-:22 \
-device e1000,netdev=ndev.0 \
-smb /home/work/Myproj/vms/share_dir
宿主机访问该虚拟机
ssh 127.0.0.1 -p 5555
虚拟机访问该共享目录
smbclient -L //10.0.2.2 -U samba1%123
虚拟机挂载该目录
sudo mount -t cifs //10.0.2.2/share ~/mnt_host -o username=samba1,password=123
更新： 2个issue
- 宿主机缺失2个网卡脚本
/etc/qemu-ifdown /etc/qemu-ifup,自己写个就行.
- 宿主机缺失2个网卡脚本
[work ~ ]$cat /etc/qemu-ifup
#!/bin/bash
#This is a qemu-ifup script for bridging.
#You can use it when starting a KVM guest with bridge mode network.
#set your bridge name
switch=br0
if [ -n "$1" ]; then
#create a TAP interface; qemu will handle it automatically.
#tunctl -u $(whoami) -t $1
#start up the TAP interface
ip link set $1 up
sleep 1
#add TAP interface to the bridge
brctl addif ${switch} $1
exit 0
else
echo "Error: no interface specified"
exit 1
fi
[work ~ ]$cat /etc/qemu-ifdown
#! /bin/sh
switch=br0
brctl delif ${switch} $1
- 同一局域网多个虚拟机有可能产生MAC冲突，造成ssh没有响应.
qemu启动脚本中修改MAC地址即可.
- 同一局域网多个虚拟机有可能产生MAC冲突，造成ssh没有响应.
-net nic,macaddr=xx:xx:xx:xx:xx:xx
宿主机操作
- 内核支持：
Device driver --> Network device support -->Universal TUN/TAP device driver support
- 用户态软件：
apt-get install uml-utilities bridge-utils
- 修改网络配置：增加
tap0和br0
$cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
+auto tap0
+iface tap0 inet manual
+up ifconfig $IFACE 0.0.0.0 up
+down ifconfig $IFACE down
+tunctl_user nmt
+auto br0
+iface br0 inet dhcp
+bridge_ports all tap0
- 启动这俩网络设备
sudo /sbin/ifup tap0
sudo /sbin/ifup br0
*启动qemu
sudo qemu-system-x86_64 --enable-kvm -m 4G -smp 2 -hda ./VMs/vm1.raw -net nic -net tap
至于虚拟机的网路配置
(啥也不做,都是默认配置)
