2015-03-17migration: Convert 'status' of MigrationInfo to use an enum typezhanghailiang
The original 'status' is an open-coded 'str' type, convert it to use an enum type. This conversion is backwards compatible, better documented and more convenient for future extensibility. In addition, Fix a typo for qapi-schema.json (just remove the typo) : s/'completed'.

Add new query vnc qmp command, for the lack of better ideas just name it "query-vnc-servers". Changes over query-vnc: * It returns a list of vnc servers, so multiple vnc server instances are covered. * Each vnc server returns a list of server sockets. Followup patch will use that to also report websockets. In case we add support for multiple server sockets server sockets (to better support ipv4+ipv6 dualstack) we can add them to the list too.

2014-11-13QMP/input-send-event: make console parameter optionalAmos Kong
The 'QemuConsole' is the input source for handler, we share some input handlers to process the input events from different QemuConsole. Normally we only have one set of keyboard, mouse, usbtablet, etc. The devices have different mask, it's fine to just checking mask to insure that the handler has the ability to process the event. I saw we try to bind console to handler in usb/dev-hid.c, but display always isn't available at that time. If we have multiseat setup (as Gerd said), we only have 'problem' in this case. Actually event from different devices have the same effect for system, it's fine to always use the first available handler without caring about the console. For send-key command, we just pass a NULL for console parameter in calling qemu_input_event_send_key(NULL, ..), but 'input-send-event' needs to care more devices. Conclusion: Generally assigning the special console is meanless, and we can't directly remove the QMP parameter for compatibility. So we can make the parameter optional. The parameter might be useful for some special condition: we have multiple devices without binding console and they all have the ability(mask) to process events, and we don't want to use the first one.

2014-08-25cpus: Define callback for QEMU "nmi" commandAlexey Kardashevskiy
This introduces an NMI (Non Maskable Interrupt) interface with a single nmi_monitor_handler() method. A machine or a device can implement it. This searches for an QOM object with this interface and if it is implemented, calls it. The callback implements an action required to cause debug crash dump on in-kernel debugger invocation. The callback returns Error**. This adds a nmi_monitor_handle() helper which walks through all objects to find the interface. The interface method is called for all found instances. This adds support for it in qmp_inject_nmi(). Since no architecture supports it at the moment, there is no change in behaviour. This changes inject-nmi command description for HMP and QMP.

2014-08-06backends: Introduce chr-testdevPaolo Bonzini
From: Paolo Bonzini <pbonzini@redhat.com> chr-testdev enables a virtio serial channel to be used for guest initiated qemu exits. hw/misc/debugexit already enables guest initiated qemu exits, but only for PC targets. chr-testdev supports any virtio-capable target. kvm-unit-tests/arm is already making use of this backend. Currently there is a single command implemented, "q". It takes a (prefix) argument for the exit code, thus an exit is implemented by writing, e.g. "1q", to the virtio-serial port. It can be used as: $QEMU ... \ -device virtio-serial-device \ -device virtserialport,chardev=ctd -chardev testdev,id=ctd or, use: $QEMU ... \ -device virtio-serial-device \ -device virtconsole,chardev=ctd -chardev testdev,id=ctd to bind it to virtio-serial port0.

2014-05-19block: optimize zero writes with bdrv_write_zeroesPeter Lieven
this patch tries to optimize zero write requests by automatically using bdrv_write_zeroes if it is supported by the format. This significantly speeds up file system initialization and should speed zero write test used to test backend storage performance. I ran the following 2 tests on my internal SSD with a 50G QCOW2 container and on an attached iSCSI storage. a) mkfs.ext4 -E lazy_itable_init=0,lazy_journal_init=0 /dev/vdX QCOW2 [off] [on] [unmap] ----- runtime: 14secs 1.1secs 1.1secs filesize: 937M 18M 18M iSCSI [off] [on] [unmap] ---- runtime: 9.3s 0.9s 0.9s b) dd if=/dev/zero of=/dev/vdX bs=1M oflag=direct QCOW2 [off] [on] [unmap] ----- runtime: 246secs 18secs 18secs filesize: 51G 192K 192K throughput: 203M/s 2.3G/s 2.3G/s iSCSI* [off] [on] [unmap] ---- runtime: 8mins 45secs 33secs throughput: 106M/s 1.2G/s 1.6G/s allocated: 100% 100% 0% * The storage was connected via an 1Gbit interface. It seems to internally handle writing zeroes via WRITESAME16 very fast. Signed-off-by: Peter Lieven <pl@kamp.de> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
