If there was added a new return value indicating success to the

of the way the function is called it would be treated it as an

But after the commit removing virDomainSetMemory usage it changed to:

This commit fixes the logic back to the original behavior except for

Some of our really old APIs are missing @flags argument. We
introduced their variants with "Flags" suffix and wired some
logic into virsh to call the new variant only if necessary. This
enables virsh to talk to older daemon which may be lacking new
APIs.
However, in case of cmdSetmem() we are talking about v0.1.1
(virDomainSetMemory()) vs. v0.9.0 (virDomainSetMemoryFlags()) and
in case of cmdSetmaxmem() we are talking about v0.0.3
(virDomainSetMaxMemory()) vs v0.9.0 (virDomainSetMemoryFlags()).
Libvirt v0.9.0 was released more than 10 years ago and recently
we dropped support for RHEL-7 which has v4.5.0 (released ~3 years
ago). Thus it is not really necessary to have support in virsh
for such old daemons.

Historically, we declared pointer type to our types:

But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to
carry some over, because they are part of public API (e.g.
virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.

Well, the code can be simplified a bit.
Note that with this change the old no flag version of APIs is

resulted in *Flags() version to be called even though it is not
necessary - VIR_DOMAIN_AFFECT_CURRENT is implied.

API design clients have no way of actually getting the error message as
the VIR_DOMAIN_EVENT_ID_BLOCK_JOB(_2) event only reports the status but
not an error and the job then vanishes.

Simplify gathering the actual return value from a passed-through QMP
command when using 'qemu-monitor-command' by adding '--return-value'
switch which just extracts the 'return' section and alternatively
reports an error if the section is not present.
This simplifies gathering of some test data where the full reply would
need to be trimmed just for the actual return value.

For long running jobs (save, managed save, dump & live migrate)
virsh runs a background thread for executing the job and then
has the main thread catch Ctrl-C for graceful shutdown, as well
as displaying progress info.
The monitoring code is written using poll, with a pipe used
to get the completion status from the thread. Using a pipe
and poll is problematic for Windows portability. This rewrites
the code to use a GMainLoop instance for monitoring stdin and
doing progress updates. The use of a pipe is entirely eliminated,
instead there is just a shared variable between both threads
containing the job completion status.
No mutex locking is used because the background thread writes
to the variable only when the main loop is still running,
while the foreground thread only reads it after the main loop
has exited.

Pvpanic device supports bit 1 as crashloaded event, it means that
guest actually panicked and run kexec to handle error by guest side.
Handle crashloaded as a lifecyle event in libvirt.
Test case:
Guest side:
before testing, we need make sure kdump is enabled,
1, build new pvpanic driver (with commit from upstream

2, insmod new kmod
3, enable crash_kexec_post_notifiers,
# echo 1 > /sys/module/kernel/parameters/crash_kexec_post_notifiers
4, trigger kernel panic

# echo c > /proc/sysrq-trigger

g_get_real_time() returns the time since epoch in microseconds.
It uses gettimeofday() internally while libvirt used clock_gettime
because it is declared async signal safe. In practice gettimeofday
is also async signal safe *provided* the timezone parameter is
NULL. This is indeed the case in g_get_real_time().

Some layered products such as oVirt have requested a way to avoid being
blocked by guest agent commands when querying a loaded vm. For example,
many guest agent commands are polled periodically to monitor changes,
and rather than blocking the calling process, they'd prefer to simply
time out when an agent query is taking too long.
This patch adds a way for the user to specify a custom agent timeout
that is applied to all agent commands.
One special case to note here is the 'guest-sync' command. 'guest-sync'
is issued internally prior to calling any other command. (For example,
when libvirt wants to call 'guest-get-fsinfo', we first call
'guest-sync' and then call 'guest-get-fsinfo').
Previously, the 'guest-sync' command used a 5-second timeout
(VIR_DOMAIN_QEMU_AGENT_COMMAND_DEFAULT), whereas the actual command that
followed always blocked indefinitely
(VIR_DOMAIN_QEMU_AGENT_COMMAND_BLOCK). As part of this patch, if a
custom timeout is specified that is shorter than
5 seconds, this new timeout is also used for 'guest-sync'. If there is
no custom timeout or if the custom timeout is longer than 5 seconds, we
will continue to use the 5-second timeout.
