The blockjob module uses 'qemuDomainAsyncJob' in it's public headers.
As I plan adding a new structure containing job data which will need to

Instead of copying the default default values upfront
and then wondering whether the user has given us a new default,
leave the per-usage TLS certdirs and secrets empty during
parsing and only fill them afterwards if they weren't provided
by the user.
This means that instead of looking whether the specific certdir
paths match the default default, the Validate function (which
is called in between parsing and setting the defaults) can error
out for missing directories if the value is present, because
it must've come from the user.

When checking the setting of accept_ra, we have assumed that all

multipath routes don't have an RTA_OIF; instead, they have an

rtnexthop having an interface. This patch adds a loop to look at the

The feature was added to QEMU in 3.1.0 and it is currently blocking
migration, which is expected to change in the future. Luckily 3.1.0 is
new enough to give us migratability hints on each feature via
query-cpu-model-expension, which means we don't need to use the
"migratable" attribute on the CPU map XML.
The kernel calls this feature arch_capabilities and RHEL/CentOS 7.* use
arch-facilities. Apparently some CPU test files were gathered with the
RHEL version of QEMU. Let's update the test files to avoid possible

This event is emitted on the monitor when a GID table in pvrdma device
is modified and the change needs to be propagate to the backend RDMA
device's GID table.
The control over the RDMA device's GID table is done by updating the
device's Ethernet function addresses.
Usually the first GID entry is determine by the MAC address, the second
by the first IPv6 address and the third by the IPv4 address. Other
entries can be added by adding more IP addresses. The opposite is the
same, i.e. whenever an address is removed, the corresponding GID entry
is removed.
The process is done by the network and RDMA stacks. Whenever an address
is added the ib_core driver is notified and calls the device driver's
add_gid function which in turn update the device.
To support this in pvrdma device we need to hook into the create_bind
and destroy_bind HW commands triggered by pvrdma driver in guest.
Whenever a changed is made to the pvrdma device's GID table a special
QMP messages is sent to be processed by libvirt to update the address of
the backend Ethernet device.

Commit 0c6ad476 updated gnulib, which rearranged some of the
conditions in gnulib wrapper headers such that compilation
started failing on BSD systems when the normal system <unistd.h>
tried to include another system header but instead got a
gnulib wrapper header in an incomplete state; this is because
gnulib headers only work if <config.h> is included first.
Commit b6f78259 papered over the symptoms of that by including
<config.h> in all the examples. But this logic is backwards -
if our examples are truly meant to be stand-alone, they should
NOT depend on how libvirt was configured, and should NOT
depend on the gnulib fixes for system quirks. In particular,
if an example does not need to link against libgnulib.la,
then it also does not need to use -Ignulib in its compile
flags, and likewise does not need to include <config.h> since
none of the gnulib wrapper headers should be interfering.
So, revert (most of) b6f78259 (except for the bogus pre-patch
use of "config.h" in admin/logging.c: if config.h is included,
it should be via <> rather than "", and must be before any
system headers); then additionally nuke all mention of
<config.h>, -Ignulib, and -llibgnu.la, making all of the
examples truly standalone.
