2013-07-15block: add drive_backup HMP commandStefan Hajnoczi1-0/+20
Make "drive_backup" available on the HMP monitor: drive_backup [-n] [-f] device target [format] The -n flag requests QEMU to reuse the image found in new-image-file, instead of recreating it from scratch. The -f flag requests QEMU to copy the whole disk, so that the result does not need a backing file. Note that this flag *must* currently be passed since the other sync modes ('none' and 'top') have not been implemented yet. Requiring it ensures that "drive_backup" behaves like "drive_mirror".

2013-07-04pci: Cleanup configuration for pci-hotplug.cDavid Gibson1-2/+2
pci-hotplug.c and the CONFIG_PCI_HOTPLUG variable which controls its compilation are misnamed. They're not about PCI hotplug in general, but rather about the pci_add/pci_del interface which are now deprecated in favour of the more general device_add/device_del interface. This patch therefore renames them to pci-hotplug-old.c and CONFIG_PCI_HOTPLUG_OLD. CONFIG_PCI_HOTPLUG=y was listed twice in {i386,x86_64}-softmmu.make for no particular reason, so we clean that up too. In addition it was included in ppc64-softmmu.mak for which the old hotplug interface was never used and is unsuitable, so we remove that too. Most of pci-hotplug.c was additionaly protected by #ifdef TARGET_I386. The small piece which wasn't is only called from the pci_add and pci_del hooks in hmp-commands.hx, which themselves were protected by #ifdef TARGET_I386. This patch therefore also removes the #ifdef from pci-hotplug-old.c, and changes the ifdefs in hmp-commands.hx to use CONFIG_PCI_HOTPLUG_OLD.

2013-06-11dump: Drop qmp_dump_guest_memory() stub and build for all targetsAndreas Färber1-2/+0
qmp_dump_guest_memory() calls dump_init() and returns an Error when cpu_get_dump_info() returns an error, as done by the stub. So there is no need to have a stub for qmp_dump_guest_memory(). Enable the documentation of the always-present dump-guest-memory command. That way we can drop CONFIG_HAVE_CORE_DUMP and leave configure completely out of the picture for target CPU features.

2013-06-05blockdev: reset werror/rerror on drive_delStefan Hajnoczi1-0/+2
Paolo Bonzini <pbonzini@redhat.com> suggested the following test case: 1. Launch a guest and wait at the GRUB boot menu: qemu-system-x86_64 -enable-kvm -m 1024 \ -drive if=none,cache=none,file=test.img,id=foo,werror=stop,rerror=stop -device virtio-blk-pci,drive=foo,id=virtio0,addr=4 2. Hot unplug the device: (qemu) drive_del foo 3. Select the first boot menu entry Without this patch the guest pauses due to ENOMEDIUM. The guest is stuck in a continuous pause loop since the I/O request is retried and fails immediately again when the guest is resumed. With this patch the error is reported to the guest. Note that this scenario actually happens sometimes during libvirt disk hot unplug, where device_del is followed by drive_del. I/O may still be submitted to the drive after drive_del if the guest does not process the PCI hot unplug notification.

2013-03-12Support for TPM command line optionsStefan Berger1-0/+2
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 Maydell1-2/+2
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.

2013-02-06hmp: Disable chardev-add and chardev-removeMarkus Armbruster1-31/+32
As a general rule, HMP commands must be built on top of the QMP API. Luiz and others have worked long & hard to make HMP conform to this rule. Commit f1088908 added chardev-add, in violation of this rule. QMP command chardev-add was added right before, with minimal features, and the idea to complete it step by step, then switch over the HMP command to use it. Unfortunately, we're not there, yet, and we don't want to release with chardev-add in a "HMP is more powerful than QMP" state. Disable the HMP command for now, along with its chardev-remove buddy.

2013-02-06qemu-char: Saner naming of memchar stuff & doc fixesMarkus Armbruster1-20/+17
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.

Note: 1. If you want to use gdb to process the core, please specify -p option. The reason why the -p option is not default is: a. guest machine in a catastrophic state can have corrupted memory, which we cannot trust. b. The guest machine can be in read-mode even if paging is enabled. For example: the guest machine uses ACPI to sleep, and ACPI sleep state goes in real-mode. 2. If you don't want to dump all guest's memory, please specify the start physical address and the length.

2012-03-15qapi: Convert migrateLuiz Capitulino1-2/+1
The migrate command is one of those commands where HMP and QMP completely mix up together. This made the conversion to the QAPI (which separates the command into QMP and HMP parts) a bit difficult. The first important change to be noticed is that this commit completes the removal of the Monitor object from migration code, started by the previous commit. Another important and tricky change is about supporting the non-detached mode. That is, if the user doesn't pass '-d' the migrate command will lock the monitor and will only release it when migration is finished. To support this in the new HMP command (hmp_migrate()), it is necessary to create a timer which runs every second and checks if the migration is still active. If it is, the timer callback will re-schedule itself to run one second in the future. If the migration has already finished, the monitor lock is released and the user can use it normally. All these changes should be transparent to the user. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
