I wrote short qemu howto install/usage on FreeBSD as host os, and in this example with Win2000 as guest os.
changelog:1. removed useless /etc/qemu-ifup script [it was used in older versions of qemu with tap/bridge interfaces]
2. added info about sound emumation inside qemu OS.
3. removed HACKS_CIRRUS from options [thx to scottro sugestion], reason here: http://forums.bsdnexus.com/viewtopic...d=14036#p14036
4. sometimes OS installation requires unload of kqemu. short: install without kqemu and the use with kqemu
Install
qemu with options showed below:
Code:
# cd /usr/ports/emulators/qemu && make install clean
Code:
Options for qemu:
[X] KQEMU Build with (alpha!) accelerator module
[ ] HACKS_CIRRUS Large display speedup (buggy!)
[ ] RTL8139_TIMER allow use of re(4) nic with FreeBSD guests
[ ] SAMBA samba dependency (for -smb)
[X] SDL SDL/X dependency (graphical output)
[X] CDROM_DMA IDE CDROM DMA
install and configure sudo:
Code:
# cd /usr/ports/security/sudo && make install clean
sudo config:
Code:
# cat > /usr/local/etc/sudoers << EOF
root ALL=(ALL) ALL
username ALL=(ALL) NOPASSWD: ALL
EOF
username is YOU.
load needed modules:
Code:
# sudo kldload aio
# sudo kldload kqemu
create Windows2000 install CD image, use
cat or
dd:
Code:
% cat /dev/acd0 > ~/qemu/win2k.iso
% dd bs=2048 if=/dev/acd0 of=~/qemu/win2k.iso
create qemu image for new OS:
Code:
% qemu-img create -f qcow2 ~/qemu/win2000.img 4G
install new os, Windows2000 in our example:
Code:
% qemu -boot d -hda ~/qemu/win2000.img -m 128 -cdrom ~/qemu/win2k.iso -win2k-hack -localtime
if You have any problems while installing the OS then unload
kqemu module and install again, then after install, load the
kqemu module again:
Code:
% sudo kldunload kqemu
% qemu -boot d -hda ~/qemu/win2000.img -m 128 -cdrom ~/qemu/win2k.iso -win2k-hack -localtime
% sudo kldload kqemu
typical usage of OS under qemu:
Code:
% qemu -hda ~/qemu/win2000.img -m 256 -localtime
typical usage of OS under qemu in snapshot mode [to commit made changes hit
left_CTRL+left_ALT+2 and type
commit]:
Code:
% qemu -hda ~/qemu/win2000.img -m 256 -localtime -snapshot
1. to switch focus between qemu mouse focus and X11 mouse focus use:
left_CTRL+left_ALT
2. to ensure that You use kqemu kernel module in user mode hit
left_CTRL+left_ALT+2 and type
info kqemu, if everything is ok You will see:
Code:
kqemu support: enabled for user code
if not You will see:
Code:
kqemu support: disabled
if disabled it will work, but terribly slow, You will be running at Pentium 75 speed at host with CPU AthlonXP 1.66GHz.
3. to switch between qemu console and qemu os emualtion use
left_CTRL+left_ALT+2 to go to console and
left_CTRL+left_ALT+1 to back to emulation.
4. enabling network on emulated os, use DHCP configuration inside emulated os to get automatic IP adress 10.x.x.x
after You quit You os inside emulated os, or by qemu console
left_CTRL+left_ALT+2 and type
quit use this command to launch again Your emulated OS:
Code:
% qemu -hda ~/qemu/win2000.img -m 256 -localtime
How to have sound in qemu OS, You just need to launch qemu the way I listed above, only with
-soundhw sb16 or
-soundhw es1370 to emulate Sound Blaster 16, or Sound Blaster 128. You can also enable standart annoying BEEP with
-soundhw pcspk. You can also enable all three of them like that:
-soundhw sb16,es1370,pcspk, or just BEEP + one of them:
-soundhw es1370,pcspk, examples
Code:
% qemu -hda ~/qemu/win2000.img -m 256 -localtime -soundhw pcspk
Code:
% qemu -hda ~/qemu/win2000.img -m 256 -localtime -soundhw es1370,pcspk
Code:
% qemu -hda ~/qemu/win2000.img -m 256 -localtime -soundhw es1370,pcspk,sb16
fluxbox add-on:
in
~/.fluxbox/apps:
Code:
# qemu
[app] (class=SDL_App)
[Workspace] {2}
[Deco] {BORDER}

The same schema works for
Solaris 10 and
WindowsXP, You only do not use
-win2k-hack.
