+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.

+FreeBSD host notes:
+- needs to run as root in order to use /dev/tap* networking (why?)
+- slirp (usermode networking) compiles but doesn't seem to work for
+me - seems to have a timer problem (time sleep 1 takes 49 seconds
+and booting sleeps for minutes at the acd0 probe), but only on
+_some_ guest systems (FreeSBIE, knoppix.)  An installed 5.2.1 guest
+system works ok (this also doesn't happen with linux as host.)  And
+enabling /dev/rtc doesn't help either... (not included since it
+needs a patch to emulators/rtc.)
+- using physical media doesn't work on 4.x hosts (missing DIOCGMEDIASIZE
+ioctl)
