This introduces a new running reason VIR_DOMAIN_RUNNING_WAKEUP,
and new suspend event type VIR_DOMAIN_EVENT_STARTED_WAKEUP.
While a wakeup event is emitted, the domain which entered into
VIR_DOMAIN_PMSUSPENDED will be transferred to "running"
with reason VIR_DOMAIN_RUNNING_WAKEUP, and a new domain lifecycle
event emitted with type VIR_DOMAIN_EVENT_STARTED_WAKEUP.
This introduces a new domain state pmsuspended to represent
the domain which has been suspended by guest power management,
e.g. (entered itno s3 state). Because a "running" state could
be confused in this case, one will see the guest is paused
actually while playing. And state "paused" is for the domain
which was paused by virDomainSuspend.
This patch introduces a new event type for the QMP event
SUSPEND:
VIR_DOMAIN_EVENT_ID_PMSUSPEND
The event doesn't take any data, but considering there might
be reason for wakeup in future, the callback definition is:
typedef void
(*virConnectDomainEventSuspendCallback)(virConnectPtr conn,
virDomainPtr dom,
int reason,
void *opaque);
"reason" is unused currently, always passes "0".
This patch introduces a new event type for the QMP event
WAKEUP:
VIR_DOMAIN_EVENT_ID_PMWAKEUP
The event doesn't take any data, but considering there might
be reason for wakeup in future, the callback definition is:

(*virConnectDomainEventWakeupCallback)(virConnectPtr conn,
virDomainPtr dom,
int reason,

This is similiar with physical world, one will be surprised if the
box starts with medium exists while the tray is open.
New tests are added, tests disk-{cdrom,floppy}-tray are for the qemu
supports "-device" flag, and disk-{cdrom,floppy}-no-device-cap are
for old qemu, i.e. which doesn't support "-device" flag.
This patch introduces a new event type for the QMP event
DEVICE_TRAY_MOVED, which occurs when the tray of a removable
disk is moved (i.e opened or closed):
VIR_DOMAIN_EVENT_ID_TRAY_CHANGE
The event's data includes the device alias and the reason
for tray status' changing, which indicates why the tray
status was changed. Thus the callback definition for the event
is:
enum {
VIR_DOMAIN_EVENT_TRAY_CHANGE_OPEN = 0,
VIR_DOMAIN_EVENT_TRAY_CHANGE_CLOSE,
\#ifdef VIR_ENUM_SENTINELS
VIR_DOMAIN_EVENT_TRAY_CHANGE_LAST
\#endif
} virDomainEventTrayChangeReason;
typedef void
(*virConnectDomainEventTrayChangeCallback)(virConnectPtr conn,
virDomainPtr dom,
const char *devAlias,
int reason,
void *opaque);

virsh.pod had several instances in which it referred to "the

documentation. Reading the document from end to end makes it clear
that it means a specific URI which was noted previously in the text,
but I had never noticed those URIs in several years of referring to
the man page. This patch adds those URIs to several additional places
in the text.

On machines with massive amounts of CPUs, the gnulib 'test-lock'
could take minutes, or even appear to deadlock, because of poor
scaling of timing interactions between multiple cores.

For precedence, note that iwhd has done the same:
https://lists.gnu.org/archive/html/bug-gnulib/2012-01/msg00311.html
We can re-enable things if gnulib ever analyzes and improves the
situation.

When a client which started non-p2p migration dies in a bad time, the
source libvirtd never clears the migration job and almost nothing can be
done with the domain without restarting the daemon. This patch makes use
of connection close callbacks and ensures that migration job is properly
discarded when the client disconnects.
Destination daemon should not rely on the client or source daemon
(depending on the type of migration) to call Finish when migration
fails, because the client may crash before it can do so. The domain
prepared for incoming migration is set to be destroyed (and migration
job cleaned up) when connection with the client closes but this is not
enough. If the associated qemu process crashes after Prepare step and
the domain is cleaned up before the connection gets closed, autodestroy
is not called for the domain and migration jobs remains set. In case the
domain is defined on destination host (i.e., it is not completely
removed once destroyed) we keep the job set for ever. To fix this, we
register a cleanup callback which is responsible to clean migration-in
job when a domain dies anywhere between Prepare and Finish steps. Note
that we can't blindly clean any job when spotting EOF on monitor since
normally an API is running at that time.
This reverts commit 61f2b6ba5f and most of
commit d8916dc8e2, which effectively
brings back commit ef1065cf5a written by
Jim Fehlig:
The qemu migration speed default is 32MiB/s as defined in migration.c
/* Migration speed throttling */
static int64_t max_throttle = (32 << 20);
There's no need to throttle migration when targeting a file, so set
migration speed to unlimited prior to migration, and restore to libvirt
default value after migration.
Default units is MB for migrate_set_speed monitor command, so
(INT64_MAX / (1024 * 1024)) is used for unlimited migration speed.
This was reverted because migration to file could not be canceled and
even monitored since qemu was not processing any monitor commands until
the migration finished. This is now different as we make sure the
file descriptor we pass to qemu is able to properly report EAGAIN.
Recent qemu changes might have helped as well.
I tested managedsave with this patch in and indeed, it is 10x faster

A few times libvirt users manually setting mac addresses have
complained of a networking failure that ends up being due to a multicast
mac address being used for a guest interface. This patch prevents that
by logging an error and failing if a multicast mac address is
encountered in each of the three following cases:
1) domain xml <interface> mac address.
2) network xml bridge mac address.
3) network xml dhcp/host mac address.
There are several other places where a mac address can be input that
aren't controlled in this manner because failure to do so has no
consequences (e.g., if the address will be used to search through
existing interfaces for a match).
The RNG has been updated to add multiMacAddr and uniMacAddr along with
the existing macAddr, and macAddr was switched to uniMacAddr where
appropriate.
If an error was encountered parsing a dhcp host entry mac address or
name, parsing would continue and log a less descriptive error that
might make it more difficult to notice the true nature of the problem.
This patch returns immediately on logging the first error.
This patch is in response to:
https://bugzilla.redhat.com/show_bug.cgi?id=798467
If a guest's tap device is created using the same MAC address the
guest uses for its own network card (which connects to the tap
device), the Linux kernel will log the following message and traffic
will not pass:
kernel: vnet9: received packet with own address as source address
This patch disallows MAC addresses with a first byte of 0xFE, but only in
the case that the MAC address is used for a guest interface that's
connected by way of a standard tap device. (In other words, the
validation is done at runtime at the same place the MAC address is
modified for the tap device, rather than when mac address is parsed,
the idea being that it is then we know for sure the address will be
problematic.)
Using inheritance, this patch cleans up the cpu_map.xml file and also
sorts all CPU features according to the feature and registry
values. Model features are sorted the same way as foeatures in the
specification.
Also few models that are related were organized together and parts of
the XML are marked with comments
If a guest is paused, we were silently ignoring the quiesce flag,
which results in unclean snapshots, contrary to the intent of the
flag. Since we can't quiesce without guest agent support, we should
instead fail if the guest is not running.
Meanwhile, if we attempt a quiesce command, but the guest agent
doesn't respond, and we time out, we may have left the command
pending on the guest's queue, and when the guest resumes parsing
commands, it will freeze even though our command is no longer
around to issue a thaw. To be safe, we must _always_ pair every
quiesce call with a counterpart thaw, even if the quiesce call
failed due to a timeout, so that if a guest wakes up and starts
processing a command backlog, it will not get stuck in a frozen
state.
* src/qemu/qemu_driver.c (qemuDomainSnapshotCreateDiskActive):
Always issue thaw after a quiesce, even if quiesce failed.
(qemuDomainSnapshotFSThaw): Add a parameter.
