Store the emulator pinning cpu mask as a pure virBitmap rather than the
virDomainPinDef since it stores only the bitmap and refactor
qemuDomainPinEmulator to do the same operations in a much saner way.
As a side effect virDomainEmulatorPinAdd and virDomainEmulatorPinDel can
be removed since they don't add any value.
In case when <vcpu ... cpuset=""> is not specified, the vcpupin array is
not guaranteed to be allocated to def->vcpus. This would cause a crash
for TCG since it does not report thread IDs for vCPUs.
We remember driver name in a new field 'drivername' within

We set VIR_DOMAIN_VIRT_VZ for 'vz' driver and
VIR_DOMAIN_VIRT_PARALLELS for 'Parallels'.

Newer binutils 'ar' has added an option 'D' for deterministic
builds, and at least on rawhide, this option is enabled by default.
But it conflicts with the 'u' optimization where the linker only
modifies libraries based on file timestamps, but can result in
different library ordering based on which files were touched last.
Thus, it results in some noisy compilation, for every CCLD line:
CCLD libvirt_driver_qemu_impl.la
ar: `u' modifier ignored since `D' is the default (see `U')
Upstream automake has decided that defaulting ARFLAGS to 'cru' is
no longer beneficial, and that switching the default to 'cr' will
both silence the noise and not penalize modern build systems.
https://lists.gnu.org/archive/html/automake-patches/2015-06/msg00000.html
But rather than wait for newer automake to propagate to all systems
that already have newer binutils, we might as well just use the new
default ourselves, even on older platforms.
* configure.ac: Default AR[_]FLAGS to 'cr', not 'cru'.

There are now many more reasons that virSocketAddrGetRange() could
fail, so it is much more informative to report the error there instead
of in the caller. (one of the two callers was previously assuming
success, which is almost surely safe based on the parsing that has
already happened to the config by that time, but it still is nicer to
account for an error "just in case")

This loop had automatic variable definitions mixed with code. This
patch moves the definitions to the top of the function and puts
cleanup for them at the bottom. No functional change.
Part of fix for: https://bugzilla.redhat.com/show_bug.cgi?id=985653
virSocketAddrGetRange() has been updated to take the network address
and prefix, and now checks that both the start and end of the range
are within that network, thus validating that the entire range of
addresses is in the network. For IPv4, it also checks that ranges to
not start with the "network address" of the subnet, nor end with the
broadcast address of the subnet (this check doesn't apply to IPv6,
since IPv6 doesn't have a broadcast or network address)
Negative tests have been added to the network update and socket tests
to verify that bad ranges properly generate an error.
This resolves: https://bugzilla.redhat.com/show_bug.cgi?id=985653
This was revealed when I made a cut-paste mistake in an upgrade to
virSocketAddrGetRange(), leading to failure to check for the end
address being outside of the defined network, but a negative test case
that should have caught the error instead returned success.
The problem was that testRange in sockettest.c was written so that
when it expected a failure, even an "unexpected success" would be
considered as an "expected failure" because of the way the check in
testRange was done. testRange had this:
if (gotsize < 0 || gotsize != size) {
return pass ? -1 : 0;
} else {
return pass ? 0 : -1;
}
but all the tests that expected a failure give "-1" as the expected
size. So in a case where we expect a failure, we would have pass ==
false and size == -1. If virSocketAddrGetRange() was incorrectly
*successful* (returned some positive number), then "gotsize != size"
would be, e.g. "276 != -1", so we would take the if clause and, since
pass == false, we would return 0 (success i.e. expected failure).
The solution is that in the case where we expect failure, we should
just ignore size - virSocketAddrGetRange() must return -1 in order for
us to report "expected failure == success".

This will allow us to use vshError() to report errors from inside
vshCommandOpt*(), instead of replicating the same logic and error
messages all over the place.
We also have more context inside the vshCommandOpt*() functions,
for example the actual value used on the command line, which means
we can produce more detailed error messages.
vshCommandOptBool() is the exception here, because it's explicitly
designed not to report any error.
The new tests deal with numeric options of three kinds: regular,
scaled and timeouts. For each, both valid and invalid inputs
are provided, hopefully covering all cases: this should allow us
to avoid regressions when changing the relevant code in virsh.
We do update pool volume object list before we actually create any
volume. If buildVol fails, we then try to delete the volume in the
storage as well as remove it from our structures. The problem is, that
any backend that supports both buildVol and deleteVol would fail in this
case which is completely unnecessary. This patch causes the update to
take place after we know a volume has been created successfully, thus no
removal in case of a buildVol failure is necessary.

Commit 198cc1d3 introduced libxl-lockd and libxl-sanlock config
files but forgot to add them to the spec file. Follow-up commit
62b18d98 added the files to daemon-driver-libxl, but missed adding
them to the daemon package when configuring libvirt
--without-driver-modules. In addition, commit 62b18d98 added
libxl-sanlock to daemon-driver-libxl, but it should be included
in lock-sanlock when libvirt is configured --with-sanlock.
The libxl tries to check if it's running in dom0 by parsing
/proc/xen/capabilities and if that fails it doesn't load.
There's no procfs interface in Xen on FreeBSD, so this check always
fails.
In addition to checking procfs, check if /dev/xen/xenstored, that's enough to
check if we're running in dom0 in FreeBSD case.
When shrinking a volume by a certain size, instead of typing
vol-resize volume 1G --delta --shrink
we allow the convience of specifying a negative value:
vol-resize volume -1G --delta --shrink
getting the same results with one more character.
A negative value only makes sense as a delta. Imply the
--delta parameter if the value is negative.
Still require --shrink, because the operation is potentially
destructive.
The guest firmware provides the same functionality as the pvpanic
device, and the relevant element should always be present in the
domain XML to reflect this fact, so add it after parsing the
definition if it wasn't there already.
The guest firmware provides the same functionality as the pvpanic
device, which is not available in QEMU on pSeries, so the domain
XML should be allowed to contain the <panic> element.
On the other hand, unlike the pvpanic device, the guest firmware
can't be configured, so report an error if an address has been
provided in the XML.

For HVM domains, vfb info must be populated in the libxl_domain_build_info
struct. Currently this is done in the libxlMakeVfbList function, but IMO
it would be cleaner to populate the build_info vfb in a separate
libxlMakeBuildInfoVfb function. libxlMakeVfbList would then handle only
vfb devices, simiar to the other libxlMake<device>List functions.
A future patch will extend libxlMakeBuildInfoVfb to support SPICE.

The disk pool recalculates the pool allocation, capacity, and available
values each time through processing a newly created disk partition. This
created an issue with the allocation setting since the code used is shared
with the refresh path. Each path calls virStorageBackendDiskReadPartitions
which initializes the pool values and then processes the partition table
from the 'libvirt_parthelper' utility output with the only difference being
create passes a specific volume to be processed while refresh pass a NULL
indicating to process all volumes. That passed volume is check during the
virStorageBackendDiskMakeVol call to see if the current partition described
by the volume key already exists. If it exists, then no adjustments are
made to the allocation and the next entry in the output is checked.
For the create path this resulted in only the most recently created
partition size would be accounted for in the 'allocation' setting. This
patch thus checks whether the incoming volume is NULL before clearing
the pool allocation value.
Commit id '2ac0e647' for https://bugzilla.redhat.com/show_bug.cgi?id=1206521
was meant to be a generic check for the CreateVol, CreateVolFrom, and
DeleteVol paths to check if the storage backend's changed the pool's view
of allocation or available values.
Unfortunately as it turns out this caused a side effect when the disk backend
created an extended partition there would be no actual storage removed from
the pool, thus the changes would not find any change in allocation or
available and incorrectly update the pool values using the size of the
extended partition. A subsequent refresh of the pool would reset the
values appropriately.
This patch modifies those checks in order to specifically not update the
pool allocation and available for only the disk backend rather than be
generic before and after checks.
