You are best off with the CVS version easiest way is as root, cd to /opt/ then... #cvs -z3 -d:pserver:anonymous@xxxxxxxxxxxxxx:/sources/qemu co qemu #cd qemu #make clean #./configure --cc=gcc32 (if on x86_64 edit config-host.mak and remove sparc-user sparc-softmmu) #make && make install you will also need kqemu-1.3.0pre5.tar.gz If you are on x86_64 there is a trick to compiling this one. I have found if you edit kqemu-linux.c and remove / comment the following lines... // #ifndef page_to_pfn // #define page_to_pfn(page) ((page) - mem_map) // #define pfn_to_page(pfn) (mem_map + (pfn)) // #endif kqemu will compile and load properly. Gets rid of mem_map errors. don't forget to modprobe kqemu Here is my qemu network start script... cat /etc/qemu-ifup ... <......................... #!/bin/bash #!/bin/sh # You need "youruser ALL=(root) NOPASSWD: /etc/qemu-ifup" in /etc/sudoers # You also need enough rights on /dev/tun # Get root if we are not yet if [ $UID -ne 0 ] then sudo $0 $1 exit fi sudo /sbin/ifconfig $1 promisc 0.0.0.0 sudo /sbin/ifconfig eth0 promisc 0.0.0.0 sudo /usr/sbin/brctl addbr br0 sudo /sbin/ifconfig br0 "eth0 original ip..." ip.ip.ip.ip netmask 255.255.255.0 up sudo /usr/sbin/brctl addif br0 eth0 sudo /usr/sbin/brctl addif br0 $1 .................................> Thus $1 (tap0 - tapxxx) and eth0 get promsc, br0 is created with eth0s ip etc. Using this I can have 4 instances of qemu going at once using same script. You may need to mod the script to get eth0 DHCP assigned address, I'm on fixed IP. I start XP with... cat startxp64.sh... #!/bin/bash cd ~/vm sudo /sbin/modprobe tun sudo /bin/chmod 666 /dev/net/tun sudo /bin/chmod 666 /dev/ttyS0 qemu-system-x86_64 -m 256 -kernel-kqemu -hda xppro -net nic,macaddr=00:09:5B:E0:5E:11 -net tap -usb -localtime -soundhw es1370 -serial /dev/ttyS0 This makes sure tun module is loaded (even though qemu uses tap) and sets perms. I also use the RS232 serial interface from Qemu so need to set perms on that. OK I know you said NO promiscuous interfaces but... This works for me. HTH
