This commit adds the QEMU driver support for CCW addresses. The current QEMU only allows virtio devices to be attached to the CCW bus. We named the new capability indicating that support QEMU_CAPS_VIRTIO_CCW accordingly. The fact that CCW devices can only be assigned to domains with a machine type of s390-ccw-virtio requires a few extra checks for machine type in qemu_command.c on top of querying QEMU_CAPS_VIRTIO_{CCW|S390}. The majority of the new functions deals with CCW address generation and management. Signed-off-by: NViktor Mihajlovski <mihajlov@linux.vnet.ibm.com>

The virCaps structure gathered a ton of irrelevant data over time that. The original reason is that it was propagated to the XML parser functions. This patch aims to create a new data structure virDomainXMLConf that will contain immutable data that are used by the XML parser. This will allow two things we need: 1) Get rid of the stuff from virCaps 2) Allow us to add callbacks to check and add driver specific stuff after domain XML is parsed. This first attempt removes pointers to private data allocation functions to this new structure and update all callers and function that require them.

qemuProcessStart expects to be run with a job already set and every caller except for qemuMigrationPrepareAny use it correctly. This bug can be observed in libvirtd logs during incoming migration as warning : qemuDomainObjEnterMonitorInternal:979 : This thread seems to be the async job owner; entering monitor without asking for a nested job is dangerous

As a side effect, this also fixes reporting disk migration process. It was added to memory migration progress, which was wrong. Disk progress has dedicated fields in virDomainJobInfo structure.

With the majority of fields in the virQEMUDriverPtr struct now immutable or self-locking, there is no need for practically any methods to be using the QEMU driver lock. Only a handful of helper APIs in qemu_conf.c now need it

The 'driver->caps' pointer can be changed on the fly. Accessing it currently requires the global driver lock. Isolate this access in a single helper, so a future patch can relax the locking constraints. Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

To avoid confusion between 'virCapsPtr' and 'qemuCapsPtr' do some renaming of various fucntions/variables. All instances of 'qemuCapsPtr' are renamed to 'qemuCaps'. To avoid that clashing with the 'qemuCaps' typedef though, rename the latter to virQEMUCaps. Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

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>

The functionality provided in virchrdev.c (previously virconsole.c) is applicable to other types of character devices besides consoles, such as channels. This patch is just code motion, renaming things such as "console" or "pty", instead using more general terms such as "character device" or "device path".

I have been testing libvirt v1.0.0 for deployment within my organization, and in the process discovered what appears to be a bug that breaks virsh attach-device, when attaching an RBD volume to an instance. First, here is the error presented, with v1.0.0 (this worked in v0.10.2): [root@host ~]# virsh attach-device W5APQ8 G84VV1.xml error: Failed to attach device from G84VV1.xml error: cannot open file 'dc3-1-test/G84VV1': No such file or directory Using git bisect, I narrowed the problem down to this as the first commit to break this setup: 4d34c929 is the first bad commit

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.

In the XML warning, we print a virsh command line that can be used to edit that XML. This patch prints UUIDs if the entity name contains special characters (like shell metacharacters, or "--" that would break parsing of the XML comment). If the entity doesn't have a UUID, just print the virsh command that can be used to edit it.

Technically, we should not be re-probing any file that qemu might be currently writing to. As such, we should cache the backing file chain prior to starting qemu. This patch adds the cache, but does not use it until the next patch. Ultimately, we want to also store the chain in domain XML, so that it is remembered across libvirtd restarts, and so that the only kosher way to modify the backing chain of an offline domain will be through libvirt API calls, but we aren't there yet. So for now, we merely invalidate the cache any time we do a live operation that alters the chain (block-pull, block-commit, external disk snapshot), as well as tear down the cache when the domain is not running. * src/conf/domain_conf.h (_virDomainDiskDef): New field. * src/conf/domain_conf.c (virDomainDiskDefFree): Clean new field. * src/qemu/qemu_domain.h (qemuDomainDetermineDiskChain): New prototype. * src/qemu/qemu_domain.c (qemuDomainDetermineDiskChain): New function. * src/qemu/qemu_driver.c (qemuDomainAttachDeviceDiskLive) (qemuDomainChangeDiskMediaLive): Pre-populate chain.

When libvirt cannot find a suitable CPU model for host CPU (easily reproducible by running libvirt in a guest), it would not provide CPU topology in capabilities XML either. Even though CPU topology is known and can be queried by virNodeGetInfo. With this patch, CPU topology will always be provided in capabilities XML regardless on the presence of CPU model.

The comment stated that you may call qemuDomainObjBeginJobWithDriver without passing qemud_driver to signal it's not locked. qemuDomainObjBeginJobWithDriver still accesses the qemud_driver structure and the lock singaling is done through a separate parameter.

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.

SELinux wants all log files opened with O_APPEND. When running non-root though, libvirtd likes to use O_TRUNC to avoid log files growing in size indefinitely. Instead of using O_TRUNC though, we can use O_APPEND and then call ftruncate() which keeps SELinux happier. Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

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.
