Build the utilities in this directory: - make - -2. Get the qemu source code: - svn co svn://svn.savannah.nongnu.org/qemu/trunk qemu - -2a. Patch the qemu code. There is currently a bug that causes qemu to - execute gPXE incredibly slowly. The bug seems to be related - to the relative prioritisation of CPU and I/O operations within - qemu. This patch (which I found via Google) isn't a proper fix, - but it does work around the problem: - patch -p0 < qemu-patch - -3. Configure qemu with - pushd qemu - ./configure --target-list=i386-softmmu,x86_64-softmmu - popd - -4. Build qemu: - make -C qemu - -5. As root, set up a TAP virtual network device: - /sbin/modprobe tun - chmod o+rw /dev/net/tun - ./tunctl -u <username> -t tap0 - /sbin/ifconfig tap0 up 10.254.254.2 netmask 255.255.255.0 - -6. As root, add the following fragment to /etc/dhcpd.conf: - subnet 10.254.254.0 netmask 255.255.255.252 { - range dynamic-bootp 10.254.254.1 10.254.254.1; - } - You will also need to add in any of your usual declarations for - gPXE, e.g. 'filename "vmlinuz.ltsp";'. Note that this setup - assumes that your DHCP server, TFTP server etc. all live on the - machine you are using for running qemu. If not, then you're on - your own. - -7. As root, restart dhcpd - /etc/init.d/dhcpd restart - -8. Build gPXE floppy disk images and pad to 1.44MB - pushd ../../src - make bin/rtl8139.dsk - popd - -9. Start qemu - ./qemu/i386-softmmu/qemu -L qemu/pc-bios \ - -net nic,model=rtl8139 -net tap,ifname=tap0 \ - -boot a -fda ../../src/bin/rtl8139.dsk - -You should see qemu start up, load up gPXE and attempt to boot from -the network. - - - -Serial console -============== - -You can use the program "serial-console" to obtain a virtual serial -console for gPXE running within qemu. Run "./serial-console" on a -spare tty (e.g. a separate xterm window) before starting qemu, and -ensure that you have enabled CONSOLE_SERIAL in config.h. - -When serial-console starts, it will print out the message "Slave pty -is /dev/pts/XX", where XX is a number. You need to append the option - - -serial /dev/pts/XX - -to the qemu command line. - -There is a manual page for "serial-console"; use "man -./serial-console.1" to view it. |
