【问题】

折腾:

【记录】Ubuntu下使用QEMU启动Linux内核

期间,去通过QEMU启动内核,结果出错:

crifan@ubuntu:etc$ sudo /opt/qemu/bin/qemu-system-arm -M versatilepb -nographic -net nic -net tap,ifname=tap0 -kernel /home/crifan/develop/crosscompile/uboot/u-boot-2013.07/u-boot

即:

/etc/qemu-ifup: 19: /etc/qemu-ifup: /usr/sbin/openvpn: not found

【解决过程】

1.去确认了普通用户和sudo都有eth0:

crifan@ubuntu:qemu$ ifconfig
eth0      Link encap:Ethernet  HWaddr 00:0c:29:e4:c8:06  
          inet6 addr: fe80::20c:29ff:fee4:c806/64 Scope:Link

          RX bytes:29594 (29.5 KB)  TX bytes:29594 (29.5 KB)

2.然后突然发现:

/usr/sbin/openvpn: not found

很明显,没找到。

所以去看看:

crifan@ubuntu:qemu$ 

所以的确是没有openvpn。

3.然后注意到之前的教程:

Virtual Development Board

中说的那句:

make two files: qemu-ifup and qemu-ifdown, but do not need openvpn line

所以,再去修改之前自己此处的qemu-ifdown把openvpn去掉:

#!/bin/sh 
# 
# Script to bring down and delete bridge br0 when QEMU exits 
# 
# Bring down eth0 and br0 
#
/sbin/ifdown eth0
/sbin/ifdown br0
/sbin/ifconfig br0 down 
# 
# Delete the bridge
#
/usr/sbin/brctl delbr br0 
# 
# bring up eth0 in "normal" mode 
#
/sbin/ifconfig eth0 -promisc
/sbin/ifup eth0 
#
# delete the tap device
#
#/usr/sbin/openvpn --rmtun --dev $1
#
# start firewall again
# 
/sbin/service firestarter start

同时也把ifup中的openvpn去掉:

#!/bin/sh 
# 
# script to bring up the tun device in QEMU in bridged mode 
# first parameter is name of tap device (e.g. tap0)
#
# some constants specific to the local host - change to suit your host
#
ETH0IPADDR=192.168.0.3
GATEWAY=192.168.0.1
BROADCAST=192.168.0.255
#
# First take eth0 down, then bring it up with IP address 0.0.0.0 
#
/sbin/ifdown eth0
/sbin/ifconfig eth0 0.0.0.0 promisc up
#
# Bring up the tap device (name specified as first argument, by QEMU)
#
#/usr/sbin/openvpn --mktun --dev $1 --user `id -un`
/sbin/ifconfig $1 0.0.0.0 promisc up
#
# create the bridge between eth0 and the tap device
#
/usr/sbin/brctl addbr br0
/usr/sbin/brctl addif br0 eth0
/usr/sbin/brctl addif br0 $1
# 
# only a single bridge so loops are not possible, turn off spanning tree protocol
#
/usr/sbin/brctl stp br0 off 
# 
# Bring up the bridge with ETH0IPADDR and add the default route 
#
/sbin/ifconfig br0 $ETH0IPADDR netmask 255.255.255.0 broadcast $BROADCAST
/sbin/route add default gw $GATEWAY
#
# stop firewall - comment this out if you don't use Firestarter
#
/sbin/service firestarter stop 

4.然后把修改后的拷贝到etc下:

crifan@ubuntu:ifup_ifdown$ gedit qemu-ifdown 
crifan@ubuntu:ifup_ifdown$ sudo cp qemu-ifup qemu-ifdown /etc/
crifan@ubuntu:ifup_ifdown$ gedit qemu-ifup 
crifan@ubuntu:ifup_ifdown$ sudo cp qemu-ifup /etc/

再重新去运行,看看结果,结果还有其他问题:

crifan@ubuntu:ifup_ifdown$ sudo /opt/qemu/bin/qemu-system-arm -M versatilepb -nographic -net nic -net tap,ifname=tap0 -kernel /home/crifan/develop/crosscompile/uboot/u-boot-2013.07/u-boot
/sbin/ifdown: interface eth0 not configured
/etc/qemu-ifup: 24: /etc/qemu-ifup: /usr/sbin/brctl: not found
/etc/qemu-ifup: 25: /etc/qemu-ifup: /usr/sbin/brctl: not found
/etc/qemu-ifup: 26: /etc/qemu-ifup: /usr/sbin/brctl: not found
/etc/qemu-ifup: 30: /etc/qemu-ifup: /usr/sbin/brctl: not found
SIOCSIFADDR: No such device
br0: ERROR while getting interface flags: No such device
SIOCSIFNETMASK: No such device
SIOCSIFBRDADDR: No such device
br0: ERROR while getting interface flags: No such device
SIOCADDRT: Network is unreachable
/etc/qemu-ifup: 39: /etc/qemu-ifup: /sbin/service: not found
/etc/qemu-ifup: could not launch network script
qemu-system-arm: -net tap,ifname=tap0: Device 'tap' could not be initialized

即,

/usr/sbin/brctl: not found

的错误。

5.结果去一搜,发现貌似brctl,也是和openvpn相关的东西。

然后再去掉试试:

ipdown:

#!/bin/sh 
# 
# Script to bring down and delete bridge br0 when QEMU exits 
# 
# Bring down eth0 and br0 
#
/sbin/ifdown eth0
/sbin/ifdown br0
/sbin/ifconfig br0 down 
# 
# Delete the bridge
#
#/usr/sbin/brctl delbr br0 
# 
# bring up eth0 in "normal" mode 
#
/sbin/ifconfig eth0 -promisc
/sbin/ifup eth0 
#
# delete the tap device
#
#/usr/sbin/openvpn --rmtun --dev $1
#
# start firewall again
# 
/sbin/service firestarter start

ifup:

#!/bin/sh 
# 
# script to bring up the tun device in QEMU in bridged mode 
# first parameter is name of tap device (e.g. tap0)
#
# some constants specific to the local host - change to suit your host
#
ETH0IPADDR=192.168.0.3
GATEWAY=192.168.0.1
BROADCAST=192.168.0.255
#
# First take eth0 down, then bring it up with IP address 0.0.0.0 
#
/sbin/ifdown eth0
/sbin/ifconfig eth0 0.0.0.0 promisc up
#
# Bring up the tap device (name specified as first argument, by QEMU)
#
#/usr/sbin/openvpn --mktun --dev $1 --user `id -un`
/sbin/ifconfig $1 0.0.0.0 promisc up
#
# create the bridge between eth0 and the tap device
#
#/usr/sbin/brctl addbr br0
#/usr/sbin/brctl addif br0 eth0
#/usr/sbin/brctl addif br0 $1
# 
# only a single bridge so loops are not possible, turn off spanning tree protocol
#
#/usr/sbin/brctl stp br0 off 
# 
# Bring up the bridge with ETH0IPADDR and add the default route 
#
/sbin/ifconfig br0 $ETH0IPADDR netmask 255.255.255.0 broadcast $BROADCAST
/sbin/route add default gw $GATEWAY
#
# stop firewall - comment this out if you don't use Firestarter
#
/sbin/service firestarter stop 

6.然后再去试试,至少解决了此处的问题,没有openvpn相关的错误了:

no openvpn related error

 

【总结】

此处,当出现:

/etc/qemu-ifup: 19: /etc/qemu-ifup: /usr/sbin/openvpn: not found

/etc/qemu-ifup: 24: /etc/qemu-ifup: /usr/sbin/brctl: not found

应该还是参考QEMU教程中,把相关的openvpn的东西,都去掉,包括openvpn和brctl。

 


结果继续还是剩下的那些“SIOCSIFADDR: No such device ”错误:

【未解决】Ubuntu下用QEMU启动内核时出错:SIOCSIFADDR: No such device
