Since threadpool increments the current number of threads according to current
load, i.e. how many jobs are waiting in the queue. The count however, is
constrained by max and min limits of workers. The logic of this new API works
like this:
1) setting the minimum
a) When the limit is increased, depending on the current number of
threads, new threads are possibly spawned if the current number of
threads is less than the new minimum limit
b) Decreasing the minimum limit has no possible effect on the current
number of threads
2) setting the maximum
a) Icreasing the maximum limit has no immediate effect on the current
number of threads, it only allows the threadpool to spawn more
threads when new jobs, that would otherwise end up queued, arrive.
b) Decreasing the maximum limit may affect the current number of
threads, if the current number of threads is less than the new
maximum limit. Since there may be some ongoing time-consuming jobs
that would effectively block this API from killing any threads.
Therefore, this API is asynchronous with best-effort execution,
i.e. the necessary number of workers will be terminated once they
finish their previous job, unless other workers had already
terminated, decreasing the limit to the requested value.
3) setting priority workers
- both increase and decrease in count of these workers have an
immediate impact on the current number of workers, new ones will be
spawned or some of them get terminated respectively.

In a few places in libvirt we busy-wait for events, for example qemu

- We need to choose a sufficiently large polling period so that

Move the logic from virDomainDiskDefDstDuplicates into
virDomainDiskDefCheckDuplicateInfo so that we don't have to loop
multiple times through the array of disks. Since the original function
was called in qemuBuildDriveDevStr, it was actually called for every
single disk which was quite wasteful.
Additionally the target uniqueness check needed to be duplicated in
the disk hotplug case, since the disk was inserted into the domain
definition after the device string was formatted and thus
virDomainDiskDefDstDuplicates didn't do anything in that case.
In the reverted commit d2e5538b1, the libxl driver was changed to copy
interface names autogenerated by libxl to the corresponding network def
in the domain's virDomainDef object. The copied name is freed when the
domain transitions to the shutoff state. But when migrating a domain,
the autogenerated name is included in the XML sent to the destination
host. It is possible an interface with the same name already exists on
the destination host, causing migration to fail.

Same as for deserializer, this method might get handy for admin one day.
The major reason for this patch is to stay consistent with idea, i.e.
when deserializer can be shared, why not serializer as well. The only
problem to be solved was that the daemon side serializer uses a code
snippet which handles sparse arrays returned by some APIs as well as
removes any string parameters that can't be returned to older clients.
This patch makes of the new virTypedParameterRemote datatype introduced
by one of the pvious patches.
Since the method is static to remote_driver, it can't even be used by our
daemon. Other than that, it would be useful to be able to use it with admin as
well. This patch uses the new virTypedParameterRemote datatype introduced in
one of previous patches.
Currently, the deserializer is hardcoded into remote_driver which makes
it impossible for admin to use it. One way to achieve a shared implementation
(besides moving the code to another module) would be pass @ret_params_val as a
void pointer as opposed to the remote_typed_param pointer and add a new extra
argument specifying which of those two protocols is being used and typecast
the pointer at the function entry. An example from remote_protocol:
struct remote_typed_param_value {
int type;
union {
int i;
u_int ui;
int64_t l;
uint64_t ul;
double d;
int b;
remote_nonnull_string s;
} remote_typed_param_value_u;
};
typedef struct remote_typed_param_value remote_typed_param_value;
struct remote_typed_param {
remote_nonnull_string field;
remote_typed_param_value value;
};
That would leave us with a bunch of if-then-elses that needed to be used across
the method. This patch takes the other approach using the new datatype
introduced in one of earlier commits.
A pretty nasty deadlock occurs while trying to rename a VM in parallel

The short description of the problem is as follows:

In some cases it may be better to have a bitmap representing state of
individual vcpus rather than iterating the definition. The new helper
creates a bitmap representing the state from the domain definition.
The name is confusing, and there are just two uses: one is a test case,
and the other will be removed as part of an upcoming refactoring of
the hostdev code.
This patch creates two bitmaps, one for macvlan device names and one
for macvtap. The bitmap position is used to indicate that libvirt is
currently using a device with the name macvtap%d/macvlan%d, where %d
is the position in the bitmap. When requested to create a new
macvtap/macvlan device, libvirt will now look for the first clear bit
in the appropriate bitmap and derive the device name from that rather
than just starting at 0 and counting up until one works.
When libvirtd is restarted, the qemu driver code that reattaches to
active domains calls the appropriate function to "re-reserve" the
device names as it is scanning the status of running domains.
Note that it may seem strange that the retry counter now starts at
8191 instead of 5. This is because we now don't do a "pre-check" for
the existence of a device once we've reserved it in the bitmap - we
move straight to creating it; although very unlikely, it's possible
that someone has a running system where they have a large number of
network devices *created outside libvirt* named "macvtap%d" or
"macvlan%d" - such a setup would still allow creating more devices
with the old code, while a low retry max in the new code would cause a
failure. Since the objective of the retry max is just to prevent an
infinite loop, and it's highly unlikely to do more than 1 iteration
anyway, having a high max is a reasonable concession in order to
prevent lots of new failures.
On the host when we start a container, it will be
placed in a cgroup path of
/machine.slice/machine-lxc\x2ddemo.scope
under /sys/fs/cgroup/*
Inside the containers' namespace we need to setup
/sys/fs/cgroup mounts, and currently will bind
mount /machine.slice/machine-lxc\x2ddemo.scope on
the host to appear as / in the container.
While this may sound nice, it confuses applications
dealing with cgroups, because /proc/$PID/cgroup
now does not match the directory in /sys/fs/cgroup
This particularly causes problems for systems and
will make it create repeated path components in
the cgroup for apps run in the container eg
/machine.slice/machine-lxc\x2ddemo.scope/machine.slice/machine-lxc\x2ddemo.scope/user.slice/user-0.slice/session-61.scope
This also causes any systemd service that uses
sd-notify to fail to start, because when systemd
receives the notification it won't be able to
identify the corresponding unit it came from.
In particular this break rabbitmq-server startup
Future kernels will provide proper cgroup namespacing
which will handle this problem, but until that time
we should not try to play games with hiding parent
cgroups.

This new function will add a single controller of the given model,
except the case of ich9-usb-ehci1 (the master controller for a USB2
controller set) in which case a set of related controllers will be
added (EHCI1, UHCI1, UHCI2, UHCI3). These controllers will not be
given PCI addresses, but should be otherwise ready to use.
"-1" is allowed for controller model, and means "default for this
machinetype". This matches the existing practice in
qemuDomainDefPostParse(), which always adds the default controller
with model = -1, and relies on the commandline builder to set a model
(that is wrong, but will be fixed later).
This replaces the virPCIKnownStubs string array that was used
internally for stub driver validation.
Advantages:
* possible values are well-defined
* typos in driver names will be detected at compile time
* avoids having several copies of the same string around
* no error checking required when setting / getting value
The names used mirror those in the
virDomainHostdevSubsysPCIBackendType enumeration.
