This patch introduces a new event type for the QMP event SUSPEND: VIR_DOMAIN_EVENT_ID_PMSUSPEND The event doesn't take any data, but considering there might be reason for wakeup in future, the callback definition is: typedef void (*virConnectDomainEventSuspendCallback)(virConnectPtr conn, virDomainPtr dom, int reason, void *opaque); "reason" is unused currently, always passes "0".

This patch introduces a new event type for the QMP event DEVICE_TRAY_MOVED, which occurs when the tray of a removable disk is moved (i.e opened or closed): VIR_DOMAIN_EVENT_ID_TRAY_CHANGE The event's data includes the device alias and the reason for tray status' changing, which indicates why the tray status was changed. Thus the callback definition for the event is: enum { VIR_DOMAIN_EVENT_TRAY_CHANGE_OPEN = 0, VIR_DOMAIN_EVENT_TRAY_CHANGE_CLOSE, \#ifdef VIR_ENUM_SENTINELS VIR_DOMAIN_EVENT_TRAY_CHANGE_LAST \#endif } virDomainEventTrayChangeReason; typedef void (*virConnectDomainEventTrayChangeCallback)(virConnectPtr conn, virDomainPtr dom, const char *devAlias, int reason, void *opaque);

Using 'unsigned long' for memory values is risky on 32-bit platforms, as a PAE guest can have more than 4GiB memory. Our API is (unfortunately) locked at 'unsigned long' and a scale of 1024, but the rest of our system should consistently use 64-bit values, especially since the previous patch centralized overflow checking. * src/conf/domain_conf.h (_virDomainDef): Always use 64-bit values for memory.

This actually wires up the new optional parameter to block_stream: http://wiki.qemu.org/Features/LiveBlockMigration/ImageStreamingAPI The error checking is still sparse, since libvirt must not use qemu-img or header probing on a qcow2 file in use by qemu to check if the backing file name is valid; so for now, libvirt is relying on qemu to diagnose an incorrect backing name. Fixing this will require libvirt to track the entire backing file chain at the time qemu is started and keeps it updated with snapshot and pull operations. * src/qemu/qemu_monitor_json.c (qemuMonitorJSONBlockJob): Add parameter, and update callers. * src/qemu/qemu_monitor_json.h (qemuMonitorJSONBlockJob): Update signature. * src/qemu/qemu_monitor.h (qemuMonitorBlockJob): Likewise. * src/qemu/qemu_driver.c (qemuDomainBlockJobImpl): Update caller. * src/qemu/qemu_monitor.c (qemuMonitorBlockJob): Likewise.

QMP commands don't need to be escaped since converting them to json also escapes special characters. When a QMP command fails, however, libvirt falls back to HMP commands. These fallback functions (qemuMonitorText*) do their own escaping, and pass the result directly to qemuMonitorHMPCommandWithFd. If the monitor is in json mode, these pre-escaped commands will be escaped again when converted to json, which can result in the wrong arguments being sent. For example, a filename test\file would be sent in json as test\\file. This prevented attaching an image file with a " or \ in its name in qemu 1.0.50, and also broke rbd attachment (which uses backslashes to escape some internal arguments.)

In the future (my next patch in fact) we may want to make decisions depending on qemu having a monitor command or not. Therefore, we want to set qemuCaps flag instead of querying on the monitor each time we are about to make that decision.

QEMU always sends details about all available block devices as an answer for "info block"/"query-block" command. On the other hand, our qemuMonitorGetBlockInfo was made for a single block devices queries only. Thus, when asking for multiple devices, we asked qemu multiple times to always get the same answer from which different parts were filtered. This patch makes qemuMonitorGetBlockInfo return a hash table of all block devices, which may later be used for getting details about specific devices.

Implements functions for both HMP and QMP mode. For HMP mode, qemu uses "M" as the units by default, so the passed "sized" is divided by 1024. For QMP mode, qemu uses "Bytes" as the units by default, the passed "sized" is multiplied by 1024. All of the monitor functions return -1 on failure, 0 on success, or -2 if not supported.

For controlled shutdown we issue a 'system_powerdown' command to the QEMU monitor. This triggers an ACPI event which (most) guest OS wire up to a controlled shutdown. There is no equiv ACPI event to trigger a controlled reboot. This patch attempts to fake a reboot. - In qemuDomainObjPrivatePtr we have a bool fakeReboot flag. - The virDomainReboot method sets this flag and then triggers a normal 'system_powerdown'. - The QEMU process is started with '-no-shutdown' so that the guest CPUs pause when it powers off the guest - When we receive the 'POWEROFF' event from QEMU JSON monitor if fakeReboot is not set we invoke the qemuProcessKill command and shutdown continues normally - If fakeReboot was set, we spawn a background thread which issues 'system_reset' to perform a warm reboot of the guest hardware. Then it issues 'cont' to start the CPUs again * src/qemu/qemu_command.c: Add -no-shutdown flag if we have JSON support * src/qemu/qemu_domain.h: Add 'fakeReboot' flag to qemuDomainObjPrivate struct * src/qemu/qemu_driver.c: Fake reboot using the system_powerdown command if JSON support is available * src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h, src/qemu/qemu_monitor_json.c, src/qemu/qemu_monitor_json.h, src/qemu/qemu_monitor_text.c, src/qemu/qemu_monitor_text.h: Add binding for system_reset command * src/qemu/qemu_process.c: Reset the guest & start CPUs if fakeReboot is set

Currently the QEMU monitor I/O handler code uses errno values to report errors. This results in a sub-optimal error messages on certain conditions, in particular when parsing JSON strings malformed data simply results in 'EINVAL'. This changes the code to use the standard libvirt error reporting APIs. The virError is stored against the qemuMonitorPtr struct, and when a monitor API is run, any existing stored error is copied into that thread's error local * src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h, src/qemu/qemu_monitor_json.c, src/qemu/qemu_monitor_text.c: Use virError APIs for all monitor I/O handling code

Currently whenever there is any failure with parsing the monitor, this is treated in the same was as end-of-file (ie QEMU quit). The domain is terminated, if not already dead. With this change, failures in parsing the monitor stream do not result in the death of QEMU. The guest continues running unchanged, but all further use of the monitor will be disabled.
