Currently the virQEMUDriverPtr struct contains an wide variety of data with varying access needs. Move all the static config data into a dedicated virQEMUDriverConfigPtr object. The only locking requirement is to hold the driver lock, while obtaining an instance of virQEMUDriverConfigPtr. Once a reference is held on the config object, it can be used completely lockless since it is immutable. NB, not all APIs correctly hold the driver lock while getting a reference to the config object in this patch. This is safe for now since the config is never updated on the fly. Later patches will address this fully. Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

If a compression binary prints something to stderr, currently it is discarded. However, it can contain useful data from debugging POV, so we should catch it.

This patch exports qemuMigrationIsAllowed and adds a new parameter to it to denote if it's a remote migration or a local migration. Local migrations are used in snapshots and saving of the machine state and have fewer restrictions. This patch also adjusts callers of the function and tweaks some error messages to be more universal.

Offline migration transfers inactive definition of a domain (which may or may not be active). After successful completion, the domain remains in its current state on source host and is defined but inactive on destination host. It's a bit more clever than virDomainGetXMLDesc() on source host followed by virDomainDefineXML() on destination host, as offline migration will run pre-migration hook to update the domain XML on destination host. Currently, copying non-shared storage is not supported during offline migration. Offline migration can be requested with a new migration flag called VIR_MIGRATE_OFFLINE (which has to be combined with VIR_MIGRATE_PERSIST_DEST flag).

Currently, if user calls virDomainAbortJob we just issue 'migrate_cancel' and hope for the best. However, if user calls the API in wrong phase when migration hasn't been started yet (perform phase) the cancel request is just ignored. With this patch, the request is remembered and as soon as perform phase starts, migration is cancelled.

For now, disk migration via block copy job is not implemented in libvirt. But when we do implement it, we have to deal with the fact that qemu does not yet provide an easy way to re-start a qemu process with mirroring still intact. Paolo has proposed an idea for a persistent dirty bitmap that might make this possible, but until that design is complete, it's hard to say what changes libvirt would need. Even something like 'virDomainSave' becomes hairy, if you realize the implications that 'virDomainRestore' would be stuck with recreating the same mirror layout. But if we step back and look at the bigger picture, we realize that the initial client of live storage migration via disk mirroring is oVirt, which always uses transient domains, and that if a transient domain is destroyed while a mirror exists, oVirt can easily restart the storage migration by creating a new domain that visits just the source storage, with no loss in data. We can make life a lot easier by being cowards for now, forbidding certain operations on a domain. This patch guarantees that we never get in a state where we would have to restart a domain with a mirroring block copy, by preventing saves, snapshots, migration, hot unplug of a disk in use, and conversion to a persistent domain (thankfully, it is still relatively easy to 'virsh undefine' a running domain to temporarily make it transient, run tests on 'virsh blockcopy', then 'virsh define' to restore the persistence). Later, if the qemu design is enhanced, we can relax our code. The change to qemudDomainDefine looks a bit odd for undoing an assignment, rather than probing up front to avoid the assignment, but this is because of how virDomainAssignDef combines both a lookup and assignment into a single function call. * src/conf/domain_conf.h (virDomainHasDiskMirror): New prototype. * src/conf/domain_conf.c (virDomainHasDiskMirror): New function. * src/libvirt_private.syms (domain_conf.h): Export it. * src/qemu/qemu_driver.c (qemuDomainSaveInternal) (qemuDomainSnapshotCreateXML, qemuDomainRevertToSnapshot) (qemuDomainBlockJobImpl, qemudDomainDefine): Prevent dangerous actions while block copy is already in action. * src/qemu/qemu_hotplug.c (qemuDomainDetachDiskDevice): Likewise. * src/qemu/qemu_migration.c (qemuMigrationIsAllowed): Likewise.

Having hostuuid in migration cookie is a nice bonus since it provides an easy way of detecting migration to the same host. However, requiring it breaks backward compatibility with older libvirt releases.

When p2p migration fails early because qemuMigrationIsAllowed or qemuMigrationIsSafe say migration should be cancelled, we fail to clear the migration-out async job. As a result of that, further APIs called for the same domain may fail with Timed out during operation: cannot acquire state change lock. Reported by Guido Winkelmann.

Save/restore with passed through USB devices currently only works if the USB device can be found at the same USB address where it used to be before saving a domain. This makes sense in case a user explicitly configure the USB address in domain XML. However, if the device was found automatically by vendor/product identification, we should try to search for that device when restoring the domain and use any device we find as long as there is only one available. In other words, the USB device can now be removed and plugged again or the host can be rebooted between saving and restoring the domain.

Using VIR_DOMAIN_XML_MIGRATABLE flag, one can request domain's XML configuration that is suitable for migration or save/restore. Such XML may contain extra run-time stuff internal to libvirt and some default configuration may be removed for better compatibility of the XML with older libvirt releases. This flag may serve as an easy way to get the XML that can be passed (after desired modifications) to APIs that accept custom XMLs, such as virDomainMigrate{,ToURI}2 or virDomainSaveFlags.

Recently, there have been some improvements made to qemu so it supports seamless migration or something very close to it. However, it requires libvirt interaction. Once qemu is migrated, the SPICE server needs to send its internal state to the destination. Once it's done, it fires SPICE_MIGRATE_COMPLETED event and this fact is advertised in 'query-spice' output as well. We must not kill qemu until SPICE server finishes the transfer.

The current qemu capabilities are stored in a virBitmapPtr object, whose type is exposed to callers. We want to store more data besides just the flags, so we need to move to a struct type. This object will also need to be reference counted, since we'll be maintaining a cache of data per binary. This change introduces a 'qemuCapsPtr' virObject class. Most of the change is just renaming types and variables in all the callers Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

We were failing to react to allocation failure when initializing a snapshot object list. Changing things to store a pointer instead of a complete object adds one more possible point of allocation failure, but at the same time, will make it easier to react to failure now, as well as making it easier for a future patch to split all virDomainSnapshotPtr handling into a separate file, as I continue to add even more snapshot code. Luckily, there was only one client outside of domain_conf.c that was actually peeking inside the object, and a new wrapper function was easy. * src/conf/domain_conf.h (_virDomainObj): Use a pointer. (virDomainSnapshotObjListInit): Rename. (virDomainSnapshotObjListFree, virDomainSnapshotForEach): New declarations. (_virDomainSnapshotObjList): Move definitions... * src/conf/domain_conf.c: ...here.

Previously, qemu did not respond to monitor commands during migration if the limit was too high. This prevented us from raising the limit earlier. The qemu issue seems to be fixed (according to my testing) and we may remove the 32Mb/s limit.
