QEMU has a monitor command 'set_cpu' which allows a specific CPU to be toggled between online& offline state. libvirt CPU hotplug does not work in terms of individual indexes CPUs. Thus to support this, we iteratively toggle the online state when the total number of vCPUs is adjusted via libvirt NB, currently untested since QEMU segvs when running this! * src/qemu/qemu_driver.c: Toggle online state for CPUs when doing hotplug * 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 monitor API for toggling a CPU's online status via 'set_cpu

Hotunplug of devices requires that we know their PCI address. Even hotplug of SCSI drives, required that we know the PCI address of the SCSI controller to attach the drive to. We can find this out by running 'info pci' and then correlating the vendor/product IDs with the devices we booted with. Although this approach is somewhat fragile, it is the only viable option with QEMU < 0.12, since there is no way for libvirto set explicit PCI addresses when creating devices in the first place. For QEMU > 0.12, this code will not be used. * src/qemu/qemu_driver.c: Assign all dynamic PCI addresses on startup of QEMU VM, matching vendor/product IDs * 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 API for fetching PCI device address mapping

The current SCSI hotplug support attaches a brand new SCSI controller for every disk. This is broken because the semantics differ from those used when starting the VM initially. In the latter case, each SCSI controller is filled before a new one is added. If the user specifies an high drive index (sdazz) then at initial startup, many intermediate SCSI controllers may be added with no drives. This patch changes SCSI hotplug so that it exactly matches the behaviour of initial startup. First the SCSI controller number is determined for the drive to be hotplugged. If any controller upto and including that controller number is not yet present, it is attached. Then finally the drive is attached to the last controller. NB, this breaks SCSI hotunplug, because there is no 'drive_del' command in current QEMU. Previous SCSI hotunplug was broken in any case because it was unplugging the entire controller, not just the drive in question. A future QEMU will allow proper SCSI hotunplug of a drive. This patch is derived from work done by Wolfgang Mauerer on disk controllers. * src/qemu/qemu_driver.c: Fix SCSI hotplug to add a drive to the correct controller, instead of just attaching a new controller. * 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 support for 'drive_add' command

This patch allows for explicit hotplug/unplug of SCSI controllers. Ordinarily this is not required, since QEMU/libvirt will attach a new SCSI controller whenever one is required. Allowing explicit hotplug of controllers though, enables the caller to specify a static PCI address, instead of auto-assigning the next available PCI slot. Or it will when we have static PCI addressing. This patch is derived from Wolfgang Mauerer's disk controller patch series. * src/qemu/qemu_driver.c: Support hotplug & unplug of SCSI controllers * 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 new API for attaching PCI SCSI controllers

This change makes the QEMU driver get pty paths from the output of the monitor 'info chardev' command. This output is structured, and contains both the name of the device and the path on the same line. This is considerably more reliable than parsing the startup log output, which requires the parsing code to know which order QEMU will print pty information in. Note that we still need to parse the log output as the monitor itself may be on a pty. This should be rare, however, and the new code will replace all pty paths parsed by the log output method once the monitor is available. * src/qemu/qemu_monitor.(c|h) src/qemu_monitor_text.(c|h): Implement qemuMonitorGetPtyPaths(). * src/qemu/qemu_driver.c: Get pty path information using qemuMonitorGetPtyPaths().

Now that drivers are using a private domain object state blob, the virDomainObjFormat/Parse methods are no longer able to directly serialize all neccessary state to/from XML. It is thus neccessary to introduce a pair of callbacks fo serializing private state.

If QEMU shuts down while we're in the middle of processing a monitor command, the monitor will be freed, and upon cleaning up we attempt to do qemuMonitorUnlock(priv->mon) when priv->mon is NULL. To address this we introduce proper reference counting into the qemuMonitorPtr object, and hold an extra reference whenever executing a command. * src/qemu/qemu_driver.c: Hold a reference on the monitor while executing commands, and only NULL-ify the priv->mon field when the last reference is released * src/qemu/qemu_monitor.h, src/qemu/qemu_monitor.c: Add reference counting to handle safe deletion of monitor objects

Change the QEMU monitor file handle watch to poll for both read & write events, as well as EOF. All I/O to/from the QEMU monitor FD is now done in the event callback thread. When the QEMU driver needs to send a command, it puts the data to be sent into a qemuMonitorMessagePtr object instance, queues it for dispatch, and then goes to sleep on a condition variable. The event thread sends all the data, and then waits for the reply to arrive, putting the response / error data back into the qemuMonitorMessagePtr and notifying the condition variable. There is a temporary hack in the disk passphrase callback to avoid acquiring the domain lock. This avoids a deadlock in the command processing, since the domain lock is still held when running monitor commands. The next commit will remove the locking when running commands & thus allow re-introduction of locking the disk passphrase callback * src/qemu/qemu_driver.c: Temporarily don't acquire lock in disk passphrase callback. To be reverted in next commit * src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h: Remove raw I/O functions, and a generic qemuMonitorSend() for invoking a command * src/qemu/qemu_monitor_text.c, src/qemu/qemu_monitor_text.h: Remove all low level I/O, and use the new qemuMonitorSend() API.
