Define the basic framework lock manager plugins. The basic plugin API for 3rd parties to implemented is defined in src/locking/lock_driver.h This allows dlopen()able modules for alternative locking schemes, however, we do not install the header.

Allow the parent process to perform a bi-directional handshake with the child process during fork/exec. The child process will fork and do its initial setup. Immediately prior to the exec(), it will stop & wait for a handshake from the parent process. The parent process will spawn the child and wait until the child reaches the handshake point. It will do whatever extra setup work is required, before signalling the child to continue. The implementation of this is done using two pairs of blocking pipes. The first pair is used to block the parent, until the child writes a single byte. Then the second pair pair is used to block the child, until the parent confirms with another single byte. * src/util/command.c, src/util/command.h, src/libvirt_private.syms: Add APIs to perform a handshake

This introduces a new domain VIR_DOMAIN_EVENT_ID_CONTROL_ERROR Which uses the existing generic callback typedef void (*virConnectDomainEventGenericCallback)(virConnectPtr conn, virDomainPtr dom, void *opaque); This event is intended to be emitted when there is a failure in some part of the domain virtualization system. Whether the domain continues to run/exist after the failure is an implementation detail specific to the hypervisor. The idea is that with some types of failure, hypervisors may prefer to leave the domain running in a "degraded" mode of operation. For example, if something goes wrong with the QEMU monitor, it is possible to leave the guest OS running quite happily. The mgmt app will simply loose the ability todo various tasks. The mgmt app can then choose how/when to deal with the failure that occured. * daemon/remote.c: Dispatch of new event * examples/domain-events/events-c/event-test.c: Demo catch of event * include/libvirt/libvirt.h.in: Define event ID and callback * src/conf/domain_event.c, src/conf/domain_event.h: Internal event handling * src/remote/remote_driver.c: Receipt of new event from daemon * src/remote/remote_protocol.x: Wire protocol for new event * src/remote_protocol-structs: add new event for checks

The migration protocol has support for a 'cookie' parameter which is an opaque array of bytes as far as libvirt is concerned. Drivers may use this for passing around arbitrary extra data they might need during migration. The QEMU driver needs to do a few things: - Pass hostname/uuid to allow strict protection against localhost migration attempts - Pass SPICE/VNC server port from the target back to the source to allow seamless relocation of client sessions - Pass lock driver state from source to destination This patch introduces the basic glue for handling cookies but only includes the host/guest UUID & name. * src/libvirt_private.syms: Export virXMLParseStrHelper * src/qemu/qemu_migration.c, src/qemu/qemu_migration.h: Parsing and formatting of migration cookies * src/qemu/qemu_driver.c: Pass in cookie parameters where possible * src/remote/remote_protocol.h, src/remote/remote_protocol.x: Change cookie max length to 16384 bytes

Migration just seems to go from bad to worse. We already had to introduce a second migration protocol when adding the QEMU driver, since the one from Xen was insufficiently flexible to cope with passing the data the QEMU driver required. It turns out that this protocol still has some flaws that we need to address. The current sequence is * Src: DumpXML - Generate XML to pass to dst * Dst: Prepare - Get ready to accept incoming VM - Generate optional cookie to pass to src * Src: Perform - Start migration and wait for send completion - Kill off VM if successful, resume if failed * Dst: Finish - Wait for recv completion and check status - Kill off VM if unsuccessful The problems with this are: - Since the first step is a generic 'DumpXML' call, we can't add in other migration specific data. eg, we can't include any VM lease data from lock manager plugins - Since the first step is a generic 'DumpXML' call, we can't emit any 'migration begin' event on the source, or have any hook that runs right at the start of the process - Since there is no final step on the source, if the Finish method fails to receive all migration data & has to kill the VM, then there's no way to resume the original VM on the source This patch attempts to introduce a version 3 that uses the improved 5 step sequence * Src: Begin - Generate XML to pass to dst - Generate optional cookie to pass to dst * Dst: Prepare - Get ready to accept incoming VM - Generate optional cookie to pass to src * Src: Perform - Start migration and wait for send completion - Generate optional cookie to pass to dst * Dst: Finish - Wait for recv completion and check status - Kill off VM if failed, resume if success - Generate optional cookie to pass to src * Src: Confirm - Kill off VM if success, resume if failed The API is designed to allow both input and output cookies in all methods where applicable. This lets us pass around arbitrary extra driver specific data between src & dst during migration. Combined with the extra 'Begin' method this lets us pass lease information from source to dst at the start of migration Moving the killing of the source VM out of Perform and into Confirm, means we can now recover if the dst host can't successfully Finish receiving migration data.

Only in drivers which use virDomainObj, drivers that query hypervisor for domain status need to be updated separately in case their hypervisor supports this functionality. The reason is also saved into domain state XML so if a domain is not running (i.e., no state XML exists) the reason will be lost by libvirtd restart. I think this is an acceptable limitation.

We already have virAsprintf, so picking a similar name helps for seeing a similar purpose. Furthermore, the prefix V before printf generally implies 'va_list', even though this variant was '...', and the old name got in the way of adding a new va_list version. global rename performed with: $ git grep -l virBufferVSprintf \ | xargs -L1 sed -i 's/virBufferVSprintf/virBufferAsprintf/g' then revert the changes in ChangeLog-old.

This patch adds functions for modify domain's persistent definition. To do error recovery in easy way, we use a copy of vmdef and update it. The whole sequence will be: make a copy of domain definition. if (flags & MODIFY_CONFIG) update copied domain definition if (flags & MODIF_LIVE) do hotplug. if (no error) save copied one to the file and update cached definition. else discard copied definition.

Child processes don't always reach _exit(); if they die from a signal, then any messages should still be accurate. Most users either expect a 0 status (thankfully, if status==0, then WIFEXITED(status) is true and WEXITSTATUS(status)==0 for all known platforms) or were filtering on WIFEXITED before printing a status, but a few were missing this check.
