2013-09-06block: Add support for throttling burst max in QMP and the command line.Benoît Canet
The max parameter of the leaky bucket throttling algorithm can be used to allow the guest to do bursts. The max value is a pool of I/O that the guest can use without being throttled at all. Throttling is triggered once this pool is empty. Signed-off-by: Benoit Canet <benoit@irqsave.net> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2013-07-29Revert "chardev: Make the name of memory device consistent"Markus Armbruster
This reverts commit 6a85e60cb994bd95d1537aafbff65816f3de4637. Commit 51767e7 "qemu-char: Add new char backend CirMemCharDriver" introduced a memory ring buffer character device driver named "memory". Commit 3949e59 "qemu-char: Saner naming of memchar stuff & doc fixes" changed the driver name to "ringbuf", along with a whole bunch of other names, with the following rationale: Naming is a mess. The code calls the device driver CirMemCharDriver, the public API calls it "memory", "memchardev", or "memchar", and the special commands are named like "memchar-FOO". "memory" is a particularly unfortunate choice, because there's another character device driver called MemoryDriver. Moreover, the device's distinctive property is that it's a ring buffer, not that's in memory. This is what we released in 1.4.0. Unfortunately, the rename missed a critical instance of "memory": the actual driver name. Thus, the new device could be used only by an entirely undocumented name. The documented name did not work. Bummer. Commit 6a85e60 fixes this by changing the documentation to match the code. It also changes some, but not all related occurences of "ringbuf" to "memory". Left alone are identifiers in C code, HMP and QMP commands. The latter are external interface, so they can't be changed. The result is an inconsistent mess. Moreover, "memory" is a rotten name. The device's distinctive property is that it's a ring buffer, not that's in memory. User's don't care whether it's in RAM, flash, or carved into chocolate tablets by Oompa Loompas. Revert the commit. Next commit will fix just the bug.

2013-07-10add timestamp to error_report()Seiji Aguchi
[Issue] When we offer a customer support service and a problem happens in a customer's system, we try to understand the problem by comparing what the customer reports with message logs of the customer's system. In this case, we often need to know when the problem happens. But, currently, there is no timestamp in qemu's error messages. Therefore, we may not be able to understand the problem based on error messages. [Solution] Add a timestamp to qemu's error message logged by error_report() with g_time_val_to_iso8601().

2013-07-09trap signals for "-serial mon:stdio"Paolo Bonzini
With mon:stdio you can exit the VM by switching to the monitor and sending the "quit" command. It is then useful to pass Ctrl-C to the VM instead of exiting. This in turn lets us stop tying the default signal handling behavior to -nographic, removing gratuitous differences between "-display none" and "-nographic". This patch changes behavior for "-display none -serial mon:stdio", as expected, but not for "-display none -serial stdio".

So after this patch, -smp n,sockets=y is the same as -smp cpus=n,sockets=y (with "cpu" being some generic thing, referring to either cores, or threads, or sockets, as before).

2013-05-03TLS support for VNC WebsocketsTim Hardeck
Added TLS support to the VNC QEMU Websockets implementation. VNC-TLS needs to be enabled for this feature to be used. The required certificates are specified as in case of VNC-TLS with the VNC parameter "x509=<path>". If the server certificate isn't signed by a rooth authority it needs to be manually imported in the browser because at least in case of Firefox and Chrome there is no user dialog, the connection just gets canceled. As a side note VEncrypt over Websocket doesn't work atm because TLS can't be stacked in the current implementation. (It also didn't work before) Nevertheless to my knowledge there is no HTML 5 VNC client which supports it and the Websocket connection can be encrypted with regular TLS now so it should be fine for most use cases.

2013-04-15block: Add support for Secure Shell (ssh) block device.Richard W.M. Jones
qemu-system-x86_64 -drive file=ssh://hostname/some/image QEMU will ssh into 'hostname' and open '/some/image' which is made available as a standard block device. You can specify a username (ssh://user@host/...) and/or a port number (ssh://host:port/...). You can also use an alternate syntax using properties (file.user, file.host, file.port, file.path). Current limitations: - Authentication must be done without passwords or passphrases, using ssh-agent. Other authentication methods are not supported. - Uses a single connection, instead of concurrent AIO with multiple SSH connections. This is implemented using libssh2 on the client side. The server just requires a regular ssh daemon with sftp-server support. Most ssh daemons on Unix/Linux systems will work out of the box. Signed-off-by: Richard W.M.

2013-03-12Add support for cancelling of a TPM commandStefan Berger
This patch adds support for cancelling an executing TPM command. In Linux for example a user can cancel a command through the TPM's sysfs 'cancel' entry using echo "1" > /sysfs/class/misc/tpm0/device/cancel This patch propagates the cancellation of a command inside a VM to the host TPM's sysfs entry. It also uses the possibility to cancel the command before QEMU VM shutdown or reboot, which helps in preventing QEMU from hanging while waiting for the completion of the command. To relieve higher layers or users from having to determine the TPM's cancel sysfs entry, the driver searches for the entry in well known locations.

2013-03-12Add a TPM Passthrough backend driver implementationStefan Berger
This patch is based of off version 9 of Stefan Berger's patch series "QEMU Trusted Platform Module (TPM) integration" and adds a new backend driver for it. This patch adds a passthrough backend driver for passing commands sent to the emulated TPM device directly to a TPM device opened on the host machine. Thus it is possible to use a hardware TPM device in a system running on QEMU, providing the ability to access a TPM in a special state (e.g. after a Trusted Boot). This functionality is being used in the acTvSM Trusted Virtualization Platform which is available on [1]. Usage example: qemu-system-x86_64 -tpmdev passthrough,id=tpm0,path=/dev/tpm0 \ -device tpm-tis,tpmdev=tpm0 \ -cdrom test.iso -boot d Some notes about the host TPM: The TPM needs to be enabled and activated. If that's not the case one has to go through the BIOS/UEFI and enable and activate that TPM for TPM commands to work as expected. It may be necessary to boot the kernel using tpm_tis.force=1 in the boot command line or 'modprobe tpm_tis force=1' in case of using it as a module.

2013-03-12Support for TPM command line optionsStefan Berger
This patch adds support for TPM command line options. The command line options supported here are ./qemu-... -tpmdev passthrough,path=<path to TPM device>,id=<id> -device tpm-tis,tpmdev=<id>,id=<other id> and ./qemu-... -tpmdev help where the latter works similar to -soundhw help and shows a list of available TPM backends (for example 'passthrough'). Using the type parameter, the backend is chosen, i.e., 'passthrough' for the passthrough driver. The interpretation of the other parameters along with determining whether enough parameters were provided is pushed into the backend driver, which needs to implement the interface function 'create' and return a TPMDriverOpts structure if the VM can be started or 'NULL' if not enough or bad parameters were provided. Monitor support for 'info tpm' has been added. It for example prints the following: (qemu) info tpm TPM devices: tpm0: model=tpm-tis \ tpm0: type=passthrough,path=/dev/tpm0,cancel-path=/sys/devices/pnp0/00:09/cancel Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Reviewed-by: Corey Bryant <coreyb@linux.vnet.ibm.com> Reviewed-by: Joel Schopp <jschopp@linux.vnet.ibm.com> Message-id: 1361987275-26289-2-git-send-email-stefanb@linux.vnet.ibm.com Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2013-02-26qemu-log: default to stderr for logging outputPeter Maydell
Switch the default for qemu_log logging output from "/tmp/qemu.log" to stderr. This is an incompatible change in some sense, but logging is mostly used for debugging purposes so it shouldn't affect production use. The previous behaviour can be obtained by adding "-D /tmp/qemu.log" to the command line. This change requires us to: * update all the documentation/help text (we take the opportunity to smooth out minor inconsistencies between the phrasing in linux-user/bsd-user/system help messages) * make linux-user and bsd-user defer to qemu-log for the default logging destination rather than overriding it themselves * ensure that all logfile closing is done via qemu_log_close() and that that function doesn't close stderr as well as the obvious change to the behaviour of do_qemu_set_log() when no logfile name has been specified.

2013-02-06qemu-char: Saner naming of memchar stuff & doc fixesMarkus Armbruster
New device, has never been released, so we can still improve things without worrying about compatibility. Naming is a mess. The code calls the device driver CirMemCharDriver, the public API calls it "memory", "memchardev", or "memchar", and the special commands are named like "memchar-FOO". "memory" is a particularly unfortunate choice, because there's another character device driver called MemoryDriver. Moreover, the device's distinctive property is that it's a ring buffer, not that's in memory. Therefore: * Rename CirMemCharDriver to RingBufCharDriver, and call the thing a "ringbuf" in the API. * Rename QMP and HMP commands from memchar-FOO to ringbuf-FOO. * Rename device parameter from maxcapacity to size (simple words are good for you). * Clearly mark the parameter as optional in documentation. * Fix error reporting so that chardev-add reports to current monitor, not stderr. * Replace cirmem in C identifiers by ringbuf. * Rework documentation. Document the impact of our crappy UTF-8 handling on reading. * QMP examples that even work. I could split this up into multiple commits, but they'd change the same documentation lines multiple times.

2013-01-21vnc: added initial websocket protocol supportTim Hardeck
This patch adds basic Websocket Protocol version 13 - RFC 6455 - support to QEMU VNC. Binary encoding support on the client side is mandatory. Because of the GnuTLS requirement the Websockets implementation is optional (--enable-vnc-ws). To activate Websocket support the VNC option "websocket"is used, for example "-vnc :0,websocket". The listen port for Websocket connections is (5700 + display) so if QEMU VNC is started with :0 the Websocket port would be 5700. As an alternative the Websocket port could be manually specified by using ",websocket=<port>" instead. Parts of the implementation base on Anthony Liguori's QEMU Websocket patch from 2010 and on Joel Martin's LibVNC Websocket implementation.
