+QEMU is a FAST! processor emulator using dynamic translation to achieve
+good emulation speed.
+QEMU has two operating modes:
+
+    * Full system emulation. In this mode, QEMU emulates a full system
+(for example a PC), including a processor and various peripherials.
+It can be used to launch different Operating Systems without rebooting
+the PC or to debug system code.
+    * User mode emulation (Linux host only). In this mode, QEMU can launch
+Linux processes compiled for one CPU on another CPU. It can be used to
+launch the Wine Windows API emulator or to ease cross-compilation and
+cross-debugging.
+
+As QEMU requires no host kernel patches to run, it is very safe and easy to use.
+
+See also the preconfigured system images on http://oszoo.org/
+Many live cd isos also work.

+FreeBSD host notes
+==================
+
+- Needs to set net.link.tap.user_open sysctl in order to use /dev/tap*
+  networking as non-root.  Don't forget to adjust device node permissions in
+  /etc/devfs.rules.
+
+- slirp (usermode networking) is fixed now in cvs, on FreeSBIE 1.0 guests you
+  still have to manually do: echo nameserver 10.0.2.3 >/etc/resolv.conf but
+  i've been told that that's normal.  (fixed on FreeSBIE 1.1.) And you have
+  to wait a bit for dhclient to do its thing; traffic to address 10.0.2.2 is
+  routed to 127.1 on the host.
+
+- Expect timer problems when guest kernel HZ is > hosts, for example time
+  sleep 1 takes 49 seconds and booting sleeps for minutes at the acd0 probe
+  with a FreeSBIE 1.0 guest, thats because its kernel is built with HZ=5000,
+  and FreeBSD's default is 100...  (no longer a problem with FreeSBIE 1.1.)
+  The linux 2.6 kernel uses 1000 by default btw.  (changed to 250 later, and
+  recent linux kernels now no longer have a fixed HZ, aka `tickless
+  kernel'...)  Enabling /dev/rtc doesn't seem to help either (not included
+  since it needs a patch to emulators/rtc.)
+
+- Update: the above problem has gotten worse with FreeBSD guests
+  somewhere before 8.0, mainly since the kernel now usually wants
+  double or even quadruple number of timer irqs compared to HZ if
+  it detects an apic (and at least early versions of FreeBSD 8 had
+  a bug that essentially halved qemu's clock rate too); the only
+  reason you usually don't see symptoms of this with FreeBSD 8
+  guests is they automatically reduce their HZ to 100 when running
+  in a VM while the default for the host kernel is still HZ=1000.
+  Workaround: you can disable the apic clock in the guest by setting
+
+	hint.apic.0.clock="0"
+
+  in loader.conf(5) (or manually at the loader prompt), if that
+  doesn't work the only things you can do is either reduce the
+  guest's HZ to, say, 100 by setting e.g.
+
+	kern.hz="100"
+
+  from the loader as above (which usually is a good idea in a VM
+  anyway and FreeBSD 8 now does by itself as mentioned), or otherwise
+  increase the host's HZ to 2000 or even 4000 from the loader in
+  the same way.
+
+- The -smb option (smb-export local dir to guest using the default
+  slirp networking) needs the samba port/package installed
+  in addition to qemu. (SAMBA knob.)
+
+- If you want to use usb devices connected to the host in the guest
+  yot need either recent 10-current (not tested yet much) or you can
+  use usbredir over the network (see below); also unless you are
+  running qemu as root you then need to fix permissions for /dev/ugen*
+  device nodes: if you are on 5.x or later (devfs) put a rule in
+  /etc/devfs.rules, activate it in /etc/rc.conf and run /etc/rc.d/devfs
+  restart.  Example devfs.rules:
+
+	[ugen_ruleset=20]
+	add path 'ugen*' mode 660 group operator
+
+  corresponding rc.conf line:
+
+	devfs_system_ruleset="ugen_ruleset"
+
+- If you want to test the new (in 0.15.0) usb network redirection (USBREDIR
+  option) see this thread by Hans de Goede <hdegoede <at> redhat.com>:
+
+	http://thread.gmane.org/gmane.comp.emulators.qemu/110176/focus=110183
+
+  Quote:
+
+  Example usage:
+
+  1) Start usbredirserver for a usb device:
+  sudo usbredirserver 045e:0772
+  2) Start qemu with usb2 support + a chardev talking to usbredirserver +
+     a usb-redir device using this chardev:
+  qemu -usb \
+    -readconfig docs/ich9-ehci-uhci.cfg \
+    -chardev socket,id=usbredirchardev,host=localhost,port=4000 \
+    -device usb-redir,chardev=usbredirchardev,id=usbredirdev ...
+
+  [you would replace docs/ich9-ehci-uhci.cfg with e.g.
+  /usr/local/share/doc/qemu/docs/ich9-ehci-uhci.cfg, but turns out
+  ehci was broken for me here with FreeBSD guests and the previous
+  qemu version at least, I got:
+
+	FETCHENTRY: entry at 22C5484 is of type 2 which is not supported yet
+processing error - resetting ehci HC
+	Assertion failed: (0), function ehci_advance_state, file /data/ports/emulators/qemu-devel/work/qemu-0.15.0/hw/usb-ehci.c, line 2045.
+
+  The new qemu version works better tho.]
+
+- Still usb: since the hub is no longer attached to the uchi controller and
+  the wakeup mechanism, resume interrupt is not implemented yet linux guests
+  will suspend the bus, i.e. they wont see devices usb_add'ed after its
+  (linux') uhci module got loaded.  Workaround: either add devices before
+  linux loads the module or rmmod and modprobe it afterwards.  [Not sure
+  if this still applies to the new libusb host code used on recent
+  10-current.]
+
+- If you get repeated `atapi_poll called!' console messages with FreeBSD
+  guests or other weird cdrom problems then thats probably because the guest
+  has atapicam loaded, which for reasons still to be determined has problems
+  with qemu's now by default enabled cdrom dma.  You can build the port with
+  CDROM_DMA disabled to disable it.  [Looks like this is fixed in recent
+  FreeBSD guest versions.]
+
+- If you build qemu wihout SDL and then get crashes running it try passing it
+  -nographic.  This should probably be default in that case...
+
+- qemu's network boot roms (-boot n) have a bug when bootfiles sizes are a
+  multiple of blksize, if this affects you (like with FreeBSD's /boot/pxeboot)
+  you can do like
+
+	cp /boot/pxeboot pxeboot-qemu && chmod +w pxeboot-qemu && echo >>pxeboot-qemu
+
+  and then use pxeboot-qemu.  Actually you need recent btx code
+  (from after 7.0 was released) because of the real mode boot
+  problem, so use at least pxeboot from there.  And I just did that
+  for the pxeboot extracted out of
+
+	ftp://ftp.freebsd.org/pub/FreeBSD/snapshots/200805/7.0-STABLE-200805-i386-bootonly.iso
+
+  and placed it here:
+
+	http://people.freebsd.org/~nox/qemu/pxeboot-qemu
+
+- If you use slirp (usernet, the default) and want to mount nfs into the guest
+  and you are not running qemu as root, then mountd(8) on the exporting box
+  needs to be run with -n in order to accept requests from ports >= 1024.
+
+- (not FreeBSD-specific:) There have been reports of qcow2 corruption with (at
+  least) win2k guests on recent kvm (which uses similar qcow2 code than qemu
+  now, see this thread:
+
+	http://lists.gnu.org/archive/html/qemu-devel/2009-02/msg00713.html -
+
+  the consensus on that thread seems to be that qcow(2) code has always been
+  experimental and you should use raw images if you want reliability; raw is
+  also usually faster.)  You should be able to migrate existing images to raw
+  using qemu-img(1)'s convert function; raw doesn't support advanced features
+  like snapshots tho.  [a few important qcow2 bugfixed have been committed in
+  the meantime so this _might_ be less of an issue now; and meanwhile there
+  also is the new qed format - I don't know how stable that one is.]
+
+- (also not FreeBSD-specific:)  It is recommended to pass raw images using the
+  new -drive syntax, specifying format=raw explicitly in order to avoid
+  malicious guests being able to exploit the format autodetection thats
+  otherwise getting used.  (Not that you should run malicious guests anyway,
+  but this eleminates at least a known attack vector.)
+
+- qemu now has improved physical cdrom support, but still there is at
+  least one known problem: you need to have the guest eject the disc if you
+  want to change it/take it out, or otherwise the guest may continue using
+  state (like size) of the old disc.  (You can also do like `change ide1-cd0
+  /dev/acd0' in the monitor after taking out the disc if a guest cannot eject
+  it itself.)
+
+- The default configuration location (qemu-ifup script etc.) has been changed
+  from /etc to PREFIX/etc (usually /usr/local/etc).  Move your files
+  accordingly.
+
+- The pcap code (-net nic... -net pcap,ifname=...) should work properly now,
+  with only one exception:  Advanced features like TSO used on the host
+  interface can cause oversize packets which now do get truncated to avoid
+  confusing/panicing guests but of course still will cause retransmissions.
+  So if you see slow throughput and `pcap_send: packet size > ..., truncating'
+  messages on qemu's tty try disabling TSO etc on the host interface at least
+  while using pcap.
+
+- kqemu is no longer supported in qemu upstream after the 0.11 branch
+  was created, which means also not in this version.  (Linux has moved
+  on to kvm now for qemu(-like) virtualization needs, so if you want qemu
+  to go faster and don't want to switch to virtualbox or stick to the older
+  emulators/qemu port which is at 0.11.1 atm and as such still supports
+  kqemu you should help getting the FreeBSD kvm port updated and
+  completed:
