Commit 3a773c43c8 introduced the testCompareNetXML2XMLResult
enumeration; however, in one instance the result variable was
assigned a value from the very similar testCompareDocXML2XMLResult
enumeration, leading to a build error.
networkxml2xmltest.c:33:42: error:
implicit conversion from enumeration type 'testCompareDomXML2XMLResult'
to different enumeration type 'testCompareNetXML2XMLResult'
[-Werror,-Wenum-conversion]
testCompareNetXML2XMLResult result = TEST_COMPARE_DOM_XML2XML_RESULT_SUCCESS;
~~~~~~ ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Use the proper value (TEST_COMPARE_NET_XML2XML_RESULT_SUCCESS) instead.
QEMU introduced the query-gic-capabilities QMP command
with commit 4468d4e0f383: use the command, if available,
to probe available GIC capabilities.
The information obtained is stored in a virQEMUCaps
instance, and will be later used to fill in a
virDomainCaps instance.
The struct contains a single boolean field, 'supported':
the meaning of this field is too generic to be limited to
devices only, and in fact it's already being used for
other things like loaders and OSs.
Instead of trying to come up with a more generic name just
get rid of the struct altogether.
libvirt handles empty source as NULL, while vz sdk as
"" thus we need a bit of conversion.

Current implementation does not detect all incompatible configurations.
For example if we have in vzsdk bootorder "cdrom1, cdrom0" (that is
"hdb, hda" in case of ide cdroms) and cdroms do not have disk
images inserted. In this case boot order check code fails to
distiguish them at all as for both PrlVmDev_GetFriendlyName gives "".
Well the consequences are only missing warnings but as
we just have introduced all the necessary tools to face the problem -
let's fix it.

Actually using disk PrlVmDev_GetFriendlyName as id on
detaching volumes is not a problem. We can only detach
hard disks and these can not have empty friendly names.
But upcoming update device functionality for cdroms
can not use disk source as id at all as update operation
typically change this same source value. Thus we will need
to use cdrom bus and cdrom target name as cdrom id. So in attempt
to use same id scheme for all purpuses lets fix hard disk
detach function to use new id.

Our intention is to use disk bus and disk target name pair
as disk id instead of name returned by PrlVmDev_GetFriendlyName.
We already have the code that extracts this pair from vzsdk
data. Let's factor it out into a function.

Prior to this patch we didn't make any attempt to prevent two entries
in the array of interfaces/PCI devices from pointing to the same
device.

This is patterned after similar functionality for domain XML tests,
but tries harder to avoid reading non-existent networkxml2xmlout data
file when parse fails.
The common idiom in the driver API implementations is roughly:
- ACL check
- BeginJob (if needed)
- AgentAvailable (if needed)
- !IsActive
A few calls had an extra !IsActive before BeginJob, which doesn't
seem to serve much use. Drop them
It isn't implemented and does not work:
error: internal error: guest failed to start: /usr/lib/libvirt/libvirt_lxc: option '--veth' requires an argument
syntax: /usr/lib/libvirt/libvirt_lxc [OPTIONS] ...
We previously threw an explicit error, but this changed in
22cff52a2b , which I suspect was
untested for LXC
So in glibc-2.23 sys/sysmacros.h is no longer included from sys/types.h
and we don't build because of the usage of major/minor/makedev macros.
Autoconf already has AC_HEADER_MAJOR macro that check where exactly
these functions/macros are defined, so let's use that.

While working on the tests for the secret initialization vector, I found
that the existing iSCSI tests were lacking in how they defined the IQN.
Many had IQN's of just 'iqn.1992-01.com.example' for one disk while using
'iqn.1992-01.com.example/1' for the second disk (same for hostdevs - guess
how they were copied/generated).
Typically (and documented this way), IQN's would include be of the form
'iqn.1992-01.com.example:storage/1' indicating an IQN using "storage" for
naming authority specific string and "/1" for the iSCSI LUN.
So modify the input XML's to use the more proper format - this of course
has a ripple effect on the output XML and the args.
Also note that the "%3A" is generated by the virURIFormat/xmlSaveUri
to represent the colon.

Wire up the server threadpool tunable APIs to virt-admin client. Also, provide
a man page for both commands.

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.

New API to retrieve current server workerpool specs. Since it uses typed

Before any getter or setter methods can be introduced, first specify a set of

In order for the client to see all thread counts and limits, current total
and free worker count getters need to be introduced. Client might also be
interested in the job queue length, so provide a getter for that too. As with
the other getters, preparing for the admin interface, mutual exclusion is used
within all getters.
Signed-off-by: Erik Skultety <eskultet@redhat.com>
So far, the values the affected getters retrieve are static, i.e. there's no
way of changing them during runtime. But admin interface will later enable
not only getting but changing them as well. So to prevent phenomenons like
torn reads or concurrent reads and writes of unaligned values, use mutual
exclusion when getting these values (writes do, understandably, use them
already).

When either creating a threadpool, or creating a new thread to accomplish a job
that had been placed into the jobqueue, every time thread-specific data need to
be allocated, threadpool needs to be (re)-allocated and thread count indicators
updated. Make the code clearer to read by compressing these operations into a
more complex one.

The event test does not try to include libvirt internals. Using a macro
named VIR_DEBUG might hint to such usage. Additionally it's useless
since it's used only in the main() function.
Modernize the message strings while touching them.
