Initial support for the new QEMU monitor protocol using JSON
as the data encoding format instead of plain text
* po/POTFILES.in: Add src/qemu/qemu_monitor_json.c
* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Hack to turn on QMP
mode. Replace with a version number check on >= 0.12 later
* src/qemu/qemu_monitor.c: Delegate to json monitor if enabled
* src/qemu/qemu_monitor_json.c, src/qemu/qemu_monitor_json.h: Add
impl of QMP protocol
* src/Makefile.am: Add src/qemu/qemu_monitor_json.{c,h}
Recent qemu releases require command option '-enable-qemu' in order
for the kvm functionality be activated. Libvirt needs to pass this flag
to qemu when starting a domain. Note that without the option,
even if both the kernel and qemu support KVM, KVM will not be activated
and VMs will be very slow.
* src/qemu/qemu_conf.h src/qemu/qemu_conf.c: parse the extra command
line option from help and add it when running kvm
* tests/qemuhelptest.c: this modified the flags output for qemu-0.10.5
and qemu-kvm-0.11.0-rc2 regression tests
Change the QEMU driver to not directly invoke the text mode monitor
APIs. Instead add a generic wrapper layer, which will eventually
invoke either the text or JSON protocol code as needed. Pass an
qemuMonitorPtr object into the monitor APIs instead of virDomainObjPtr
to complete the de-coupling of the monitor impl from virDomainObj
data structures
* src/qemu/qemu_conf.h: Remove qemuDomainObjPrivate definition
* src/qemu/qemu_driver.c: Add qemuDomainObjPrivate definition.
Pass qemuMonitorPtr into all monitor APIs instead of the
virDomainObjPtr instance.
* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h: Add thin
wrappers for all qemuMonitorXXX command APIs, calling into
qemu_monitor_text.c/h
* src/qemu/qemu_monitor_text.c, src/qemu/qemu_monitor_text.h:
Rename qemuMonitor -> qemuMonitorText & update to accept
qemuMonitorPtr instead of virDomainObjPtr
Introduce a new qemuDomainObjPrivate object which is used to store
the private QEMU specific data associated with each virDomainObjPtr
instance. This contains a single member, an instance of the new
qemuMonitorPtr object which encapsulates the QEMU monitor state.
The internals of the latter are private to the qemu_monitor* files,
not to be shown to qemu_driver.c
* src/qemu/qemu_conf.h: Definition of qemuDomainObjPrivate.
* src/qemu/qemu_driver.c: Register a functions for creating
and freeing qemuDomainObjPrivate instances with the domain
capabilities. Remove the qemudDispatchVMEvent() watch since
I/O watches are now handled by the monitor code itself. Pass
a new qemuHandleMonitorEOF() callback into qemuMonitorOpen
to allow notification when the monitor quits.
* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h: Introduce
the 'qemuMonitor' object. Temporarily add new APIs
qemuMonitorWrite, qemuMonitorRead, qemuMonitorWaitForInput
to allow text based monitor impl to perform I/O.
* src/qemu/qemu_monitor_text.c: Call APIs for reading/writing
to monitor instead of accessing the file handle directly.
* src/qemu/qemu.conf src/qemu/qemu_conf.c src/qemu/qemu_conf.h: there is
a new config type option for mac filtering
* src/qemu/qemu_bridge_filter.[ch]: new module for the ebtable entry points
* src/qemu/qemu_driver.c: plug the MAC filtering at the right places
in the domain life cycle
* src/Makefile.am po/POTFILES.in: add the new module
* src/qemu/qemu_conf.h, src/qemu/qemu_conf.c: Remove prefix arg
from qemuBuildHostNetStr which is no longer required
* src/qemu/qemu_driver.c: Refactor to use qemuMonitorAddHostNetwork()
API for adding host network
* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h: Add new
qemuMonitorAddHostNetwork() method for adding host networks
* src/qemu/qemu_conf.c: Remove separator from qemuBuildNicStr()
args, and remove hardcoded 'nic' prefix. Leave it upto callers
instead
* src/qemu/qemu_driver.c: Switch over to using the new
qemuMonitorAddPCINetwork() method for NIC hotplug
* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h: Add new
qemuMonitorAddPCINetwork API for PCI network device hotplug
Latest upstream QEMU can be built with Xen support, which introduces
a -xen-domid argument. This was mistakenly detected as -domid due
to old Xenner support. Adapt to cope with both syntax. Also only
set domid if the virt type is xen, or the guest type is xen
* src/qemu_conf.c, src/qemu_conf.h: Detect new -xen-domid flag in
preference to -domid.
* tests/qemuxml2argvdata/qemuxml2argv-bootloader.args,
tests/qemuxml2argvdata/qemuxml2argv-input-xen.args: Add missing
-domid param
* tests/qemuxml2argvdata/qemuxml2argv-misc-uuid.args: Remove bogus
-boot param.
* tests/qemuxml2argvtest.c: Add missing QEMUD_CMD_FLAG_DOMID params
