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

1100 - Needs to set net.link.tap.user_open sysctl in order to use /dev/tap*
1101 networking as non-root. Don't forget to adjust device node permissions in
1104 - slirp (usermode networking) is fixed now in cvs, on FreeSBIE 1.0 guests you
1105 still have to manually do: echo nameserver 10.0.2.3 >/etc/resolv.conf but
1106 i've been told that that's normal. (fixed on FreeSBIE 1.1.) And you have
1107 to wait a bit for dhclient to do its thing; traffic to address 10.0.2.2 is
1108 routed to 127.1 on the host.
1110 - Expect timer problems when guest kernel HZ is > hosts, for example time
1111 sleep 1 takes 49 seconds and booting sleeps for minutes at the acd0 probe
1112 with a FreeSBIE 1.0 guest, thats because its kernel is built with HZ=5000,
1113 and FreeBSD's default is 100... (no longer a problem with FreeSBIE 1.1.)
1114 The linux 2.6 kernel uses 1000 by default btw. (changed to 250 later, and
1115 recent linux kernels now no longer have a fixed HZ, aka `tickless
1116 kernel'...) Enabling /dev/rtc doesn't seem to help either (not included
1117 since it needs a patch to emulators/rtc.)
1119 - Update: the above problem has gotten worse with FreeBSD guests
1120 somewhere before 8.0, mainly since the kernel now usually wants
1121 double or even quadruple number of timer irqs compared to HZ if
1122 it detects an apic (and at least early versions of FreeBSD 8 had
1123 a bug that essentially halved qemu's clock rate too); the only
1124 reason you usually don't see symptoms of this with FreeBSD 8
1125 guests is they automatically reduce their HZ to 100 when running
1126 in a VM while the default for the host kernel is still HZ=1000.
1127 Workaround: you can disable the apic clock in the guest by setting
1129 hint.apic.0.clock="0"
1131 in loader.conf(5) (or manually at the loader prompt), if that
1132 doesn't work the only things you can do is either reduce the
1133 guest's HZ to, say, 100 by setting e.g.
1137 from the loader as above (which usually is a good idea in a VM
1138 anyway and FreeBSD 8 now does by itself as mentioned), or otherwise
1139 increase the host's HZ to 2000 or even 4000 from the loader in
1142 - The -smb option (smb-export local dir to guest using the default
1143 slirp networking) needs the samba port/package installed
1144 in addition to qemu. (SAMBA knob.)
1146 - If you want to use usb devices connected to the host in the guest
1147 yot need either recent 10-current (not tested yet much) or you can
1148 use usbredir over the network (see below); also unless you are
1149 running qemu as root you then need to fix permissions for /dev/ugen*
1150 device nodes: if you are on 5.x or later (devfs) put a rule in
1151 /etc/devfs.rules, activate it in /etc/rc.conf and run /etc/rc.d/devfs
1152 restart. Example devfs.rules:
1155 add path 'ugen*' mode 660 group operator
1157 corresponding rc.conf line:
1159 devfs_system_ruleset="ugen_ruleset"
1161 - If you want to test the new (in 0.15.0) usb network redirection (USBREDIR
1162 option) see this thread by Hans de Goede <hdegoede <at> redhat.com>:
1164 http://thread.gmane.org/gmane.comp.emulators.qemu/110176/focus=110183
1170 1) Start usbredirserver for a usb device:
1171 sudo usbredirserver 045e:0772
1172 2) Start qemu with usb2 support + a chardev talking to usbredirserver +
1173 a usb-redir device using this chardev:

1176 -chardev socket,id=usbredirchardev,host=localhost,port=4000 \
1177 -device usb-redir,chardev=usbredirchardev,id=usbredirdev ...

1180 /raven/share/doc/qemu/docs/ich9-ehci-uhci.cfg, but turns out

1182 qemu version at least, I got:
1184 FETCHENTRY: entry at 22C5484 is of type 2 which is not supported yet processing error - resetting ehci HC
1185 Assertion failed: (0), function ehci_advance_state, file /data/ports/emulators/qemu-devel/work/qemu-0.15.0/hw/usb-ehci.c, line 2045.
1187 The new qemu version works better tho.]
1189 - Still usb: since the hub is no longer attached to the uchi controller and
1190 the wakeup mechanism, resume interrupt is not implemented yet linux guests
1191 will suspend the bus, i.e. they wont see devices usb_add'ed after its
1192 (linux') uhci module got loaded. Workaround: either add devices before
1193 linux loads the module or rmmod and modprobe it afterwards. [Not sure
1194 if this still applies to the new libusb host code used on recent
1197 - If you build qemu wihout SDL and then get crashes running it try passing it
1198 -nographic. This should probably be default in that case...
1200 - qemu's network boot roms (-boot n) have a bug when bootfiles sizes are a
1201 multiple of blksize, if this affects you (like with FreeBSD's /boot/pxeboot)
1204 cp /boot/pxeboot pxeboot-qemu && chmod +w pxeboot-qemu && echo >>pxeboot-qemu
1206 and then use pxeboot-qemu. Actually you need recent btx code
1207 (from after 7.0 was released) because of the real mode boot
1208 problem, so use at least pxeboot from there. And I just did that
1209 for the pxeboot extracted out of
1211 ftp://ftp.freebsd.org/pub/FreeBSD/snapshots/200805/7.0-STABLE-200805-i386-bootonly.iso
1215 http://people.freebsd.org/~nox/qemu/pxeboot-qemu
1217 - If you use slirp (usernet, the default) and want to mount nfs into the guest
1218 and you are not running qemu as root, then mountd(8) on the exporting box
1219 needs to be run with -n in order to accept requests from ports >= 1024.
1221 - (not FreeBSD-specific:) There have been reports of qcow2 corruption with (at
1222 least) win2k guests on recent kvm (which uses similar qcow2 code than qemu
1223 now, see this thread:
1225 http://lists.gnu.org/archive/html/qemu-devel/2009-02/msg00713.html -
1227 the consensus on that thread seems to be that qcow(2) code has always been
1228 experimental and you should use raw images if you want reliability; raw is
1229 also usually faster.) You should be able to migrate existing images to raw
1230 using qemu-img(1)'s convert function; raw doesn't support advanced features
1231 like snapshots tho. [a few important qcow2 bugfixed have been committed in
1232 the meantime so this _might_ be less of an issue now; and meanwhile there
1233 also is the new qed format - I don't know how stable that one is.]
1235 - (also not FreeBSD-specific:) It is recommended to pass raw images using the
1236 new -drive syntax, specifying format=raw explicitly in order to avoid
1237 malicious guests being able to exploit the format autodetection thats
1238 otherwise getting used. (Not that you should run malicious guests anyway,
1239 but this eleminates at least a known attack vector.)
1241 - qemu now has improved physical cdrom support, but still there is at
1242 least one known problem: you need to have the guest eject the disc if you
1243 want to change it/take it out, or otherwise the guest may continue using
1244 state (like size) of the old disc. (You can also do like `change ide1-cd0
1245 /dev/acd0' in the monitor after taking out the disc if a guest cannot eject
1248 - The default configuration location (qemu-ifup script etc.) has been changed
1249 from /etc to PREFIX/etc (usually /raven/etc). Move your files accordingly.
1251 - The pcap code (-net nic... -net pcap,ifname=...) should work properly now,
1252 with only one exception: Advanced features like TSO used on the host
1253 interface can cause oversize packets which now do get truncated to avoid
1254 confusing/panicing guests but of course still will cause retransmissions.
1255 So if you see slow throughput and `pcap_send: packet size > ..., truncating'
1256 messages on qemu's tty try disabling TSO etc on the host interface at least
