Gentoo 系統 KVM 橋接 tap 啟動指令碼

Gentoo 啟動 init 機制不同於 Debian 和 Redhat, 具體細節尚未總結。

現備份一 KVM tap 啟動指令碼：kvm_net

#!/sbin/runscript# Copyright chencheng use kvm# Distributed under the terms of the GNU General Public License v2# $Header: $user_id=999dev_num=3depend() {    need net.br0    need modules}start() {    ebegin "Start kvm-net"    /sbin/modprobe kvm-intel    #tapx=`tunctl -u nehc|awk '{print $2}'|cut -c 2,3,4,5`    for((i=0;i<${dev_num};i++))    do        tapx=`/usr/bin/tunctl -b -u ${user_id}`        brctl addif br0 ${tapx}        ifconfig ${tapx} promisc up        echo "${tapx} ready now! "    done    eend $?}stop() {    ebegin "Stop kvm-net"    for((i=0;i<${dev_num};i++))    do        brctl delif br0 tap$i        ifconfig tap$i down        tunctl -d tap$i    done    /sbin/modprobe -r kvm-intel    eend $?}restart() {    stop    start}

啟動指令碼不同於普通指令碼在於可以：rc-update add kvm-net 將 kvm-net 加入運行層級

另外，貼一 kvm 指令碼：start_kvm

#!/bin/bash# created by chencheng# use it to start virtual machine # $1 refer machine name# $2 refer tap namekvm -net nic,macaddr=00:00:00:00:00:00 -net tap,ifname=$2,script=no,downscript=no -m 300 /home/nehc/vms/$1/$1.img -daemonize      

這個就簡單啦 ....
