Qemu simulation sparc32

1. $ wget http://wiki.qemu-project.org/download/qemu-1.4.1.tar.bz2

2. $ tar-xjf qemu-1.4.1.tar.bz2

3. $ CD qemu-1.4.1

$./Configure

# Make install

4. $ qemu-sparc64-version

Qemu-sparc64 version 1.4.1, copyright (c) 2003-2008 Fabrice bellard

5. Create a disk image

$ Mkdir spark

$ CD spark

$ Qemu-IMG create-F qcow hda. IMG 40g

Because the qcow format is used, all non-empty sectors are written into the file. Therefore, the disk file is small.

$ Du-H hda. img

6. Obtain the spark kernel Image

Currently, there is a problem with the latest Debian support.

// The Last Debian release to support sparc32 (sun4m) was etch (4.0)

$ Http://cdimage.debian.org/cdimage/archive/4.0_r9/sparc/iso-cd/debian-40r9-sparc-netinst.iso

7. Install Debian

$ Qemu-system-iSCSI-hda. IMG-CDROM debian-40r9-sparc-netinst.iso-boot d

The boot option specifies to boot from the CD-ROM. Parameter d specifies the boot from the CD-ROM, where a specifies the boot from the floppy disk, c

Specify boot from the hard disk (default), while n specify boot from the network.



8. Start the system

$ Qemu-system-iSCSI-hda. IMG-boot C

9. Configure the network

-Make sure that config_tun is configured on the host kernel.

$ Grep config_tun/boot/config-'uname-R'

# Config_tun = m/config_tun = y

-Load the Tun Module

# Modprobe Tun

-Ensure that config_bridge is configured for the host kernel.

-Modify the network configuration file/etc/Network/interfaces of the host.

Static Configuration:

Auto br0

Iface br0 Inet static

Address 192.168.2.254

Network 192.168.2.0

Netmask 255.255.255.0

Broadcast 192.168.2.255

Gateway 192.168.2.1

Bridge_ports eth0

Dynamic Configuration:

Auto br0

Iface br0 Inet DHCP

Bridge_ports eth0

Bridge_maxwait 0



-Install required tools

# Apt-Get install bridge-utils

-Restart the network.

#/Etc/init. d/networking restart

-Create a script/etc/qemu-IFUP, which is automatically executed when qemu is started.

#! /Bin/sh

Echo "executing/etc/qemu-IFUP"

Echo "bringing up $1 for bridged mode ..."

Sudo/sbin/ifconfig $1 0.0.0.0 promisc up

Echo "adding $1 to br0.0 ..."

Sudo/usr/sbin/brctl addif br0 $1

Sleep 2

In fact, it is to add tap0 to br0 (Bridge, which can be considered as a hub with multiple ports.



10. Start qemu

# Qemu-system-iSCSI-hda. IMG-net Nic, macaddr = 00: 16: 3E: 00: 00: 01-net tap



11. Configure the network in qemu

# Ifconfig eth1 192.168.1.123 up

// According to the IP address of br0 in the host, my IP address is br0 192.168.1.101

Ping host

# Ping 192.168.1.101

Ping qemu from the host

# Ping 192.168.1.123



If the configuration is normal, you can access each other.

12. qemu connected to the Internet



-Set host

Enable the host forwarding function to ensure that the/proc/sys/NET/IPv4/ip_forward value is 1.

-??? What is the function ???

# Iptables-T Nat-A postrouting-J Masquerade



-Now you can ping the Internet IP address.

# Ping 119.75.217.56

-Configure domain name resolution

Write the content in/etc/resolv. conf under the host to/etc/resolv. conf of the qemu VM.

Now, you can ping the Internet domain name.

# Ping www.baidu.com

13. If you need to install other software, you can copy the installation from the pool in the debian-40r9-sparc-netinst.iso.

# Mount-o loop debian-40r9-sparc-netinst.iso/mnt
