The reboot event is not a normal lifecycle event, since the
virtual machine on the host does not change state. Rather the
guest OS is resetting the virtual CPUs. ie, the QEMU process
does not restart. Thus, this does not belong in the current
lifecycle events callback.
This introduces a new event type
VIR_DOMAIN_EVENT_ID_REBOOT
It takes no parameters, besides the virDomainPtr, so it can
use the generic callback signature.
* daemon/remote.c: Dispatch reboot events to client
* examples/domain-events/events-c/event-test.c: Watch for
reboot events
* include/libvirt/libvirt.h.in: Define new reboot event ID
* src/conf/domain_event.c, src/conf/domain_event.h,
src/libvirt_private.syms: Extend API to handle reboot events
* src/qemu/qemu_driver.c: Connect to the QEMU monitor event
for reboots and emit a libvirt reboot event
* src/remote/remote_driver.c: Receive and dispatch reboot
events to application
* src/remote/remote_protocol.x: Wire protocol definition for
reboot events
The current internal domain events API tracks callbacks based on
the function pointer, and only supports lifecycle events. This
adds new internal APIs for registering callbacks for other event
types. These new APIs are postfixed with the word 'ID' to indicate
that they operated based on event ID, instead of hardcoded to
lifecycle events
* src/conf/domain_event.c, src/conf/domain_event.h,
src/libvirt_private.syms: Add new APIs for handling callbacks
for non-lifecycle events
The internal domain events APIs are designed to handle the lifecycle
events. This needs to be refactored to allow arbitrary new event
types to be handled.
* The signature of virDomainEventDispatchFunc changes to use
virConnectDomainEventGenericCallback instead of the lifecycle
event specific virConnectDomainEventCallback
* Every registered callback gains a unique ID to allow its
removal based on ID, instead of function pointer
* Every registered callback gains an 'eventID' to allow callbacks
for different types of events to be distinguished
* virDomainEventDispatch is adapted to filter out callbacks
whose eventID does not match the eventID of the event being
dispatched
* virDomainEventDispatch is adapted to filter based on the
domain name and uuid, if this filter is set for a callback.
* virDomainEvent type/detail fields are moved into a union to
allow different data fields for other types of events to be
added later
* src/conf/domain_event.h, src/conf/domain_event.c: Refactor
to allow handling of different types of events
* src/lxc/lxc_driver.c, src/qemu/qemu_driver.c,
src/remote/remote_driver.c, src/test/test_driver.c,
src/xen/xen_driver.c: Change dispatch function signature
to use virConnectDomainEventGenericCallback
The virtual box driver was directly accesing the domain events
structs instead of using the APIs provided. To prevent this kind
of abuse, make the struct definitions private, forcing use of the
internal APIs. This requires adding one extra internal API.
* src/conf/domain_event.h, src/conf/domain_event.c: Move
virDomainEventCallback and virDomainEvent structs into
the source file instead of header
* src/vbox/vbox_tmpl.c: Use official APIs for dispatching domain
events instead of accessing structs directly.
Use the ATTRIBUTE_NONNULL annotation to mark some virConnectPtr
args as mandatory non-null so the compiler can warn of mistakes
* src/conf/domain_event.h: All virConnectPtr args must be non-null
* src/qemu/qemu_conf.h: qemudBuildCommandLine and
qemudNetworkIfaceConnect() must be given non-null connection
* tests/qemuxml2argvtest.c: Provide a non-null (dummy) connection to
qemudBuildCommandLine()
* src/capabilities.c, src/capabilities.h, src/domain_conf.c,
src/domain_conf.h, src/domain_event.c, src/domain_event.h,
src/interface_conf.c, src/interface_conf.h,
src/network_conf.c, src/network_conf.h, src/node_device_conf.c,
src/node_device_conf.h, src/secret_conf.c, src/secret_conf.h,
src/storage_conf.c, src/storage_conf.h, src/storage_encryption_conf.c,
src/storage_encryption_conf.h: Move to src/conf/
* src/Makefile.am: Add -Isrc/conf to the individual build targets
which need to use XML config APIs. Remove LIBXML_CFLAGS, LIBSSH2_CFLAGS
and SELINUX_CFLAGS from global INCLUDES and only have them in build
targets which actually need them. Create a libvirt_conf.la
convenience library for all config parsers
* src/hostusb.h: Remove bogus include of domain_conf.h
* tests/Makefile.am: Add -Isrc/conf. Remove bogus -I$builddir/src
since it never has any generated header files
* daemon/Makefile.am: Add -Isrc/conf
* proxy/Makefile.am: Add -Isrc/conf and cope with renamed files
* src/hash.c: Remove bogus include of libxml/threads.h
