Using one Makefile per example subdirectory essentially serializes 'make'
calls. Convert to one example/Makefile that builds and distributes
all the subdir files. This reduces example/ rebuild time from about 5.8
seconds to 1.5 seconds on my machine.
One slight difference is that we no longer ship Makefile.am with the
examples in the rpm. This was virtually useless anyways since the Makefile
was very specific to libvirt infrastructure, so wasn't generically
reusable anyways.
Tested with 'make distcheck' and 'make rpm'
No only coverity warns about this, but it kind of makes sense
too. We have a test whether host supports IOMMU. Some platforms
don't have it, I know. But in that case we should print a message
that it's unknown whether platform has it or not.
Before:
(no output)
After:
QEMU: Checking for device assignment IOMMU support : WARN (Unknown if this platform has IOMMU support)

This function may be called with @dconnuri == NULL, e.g. from
virDomainMigrateToURI3() if the flags are missing
VIR_MIGRATE_PEER2PEER flag. Moreover, all later functions called
from here do wrap it into NULLSTR() so why not do the same here?

The condition was checking for UHCI (and OHCI for ppc64) availability so
that it can specify the proper device instead of legacy usb. However,
for ppc64, we don't need to check both OHCI and UHCI, but only OHCI as
that is the legacy default. The condition is so big that it was just a
matter of time when someone will make a mistake there, so let's use more
lines so that it is visible what the condition checks for.
This fixes usage of -device instead of -usb for ppc64 that supports
pci-usb-ohci and does not support piix3-usb-uhci.

Future changes will make some of these tests dependent on specific
QEMUCaps flags, so wire up the basic handling. Flags will be added
in future patches.
For the standard active/inactive XML testing, if we leave the file loading
up to the generic XML2XML infrastructure, we get the benefit of
VIR_TEST_REGENERATE_OUTPUT, at the price of a few more disk reads. Seems
worth it.
Since test files are formatted predictably nowadays, we can make
VIR_TEST_REGENERATE_OUTPUT handle most cases for us with a simple
replacement. test-wrap-argv.pl is still canon, but this bit makes
it easier to confirm test output changes during active development.
The libxl_device_nic structure supports specifying an outgoing rate
limit based on a time interval and bytes allowed per interval. In xl
config a rate limit is specified as "<RATE>/s@<INTERVAL>". INTERVAL
is optional and defaults to 50ms.
libvirt expresses outgoing limits by average (required), peak, burst,
and floor attributes in units of KB/s. This patch supports the outgoing
bandwidth limit by converting the average KB/s to bytes per interval
based on the same default interval (50ms) used by xl.

Both xm and xl config have long supported specifying vif rate
limiting, e.g.
vif = [ 'mac=00:16:3E:74:3d:76,bridge=br0,rate=10MB/s' ]
Add support for mapping rate to and from <bandwidth> in the xenconfig
parser and formatter. rate is mapped to the required 'average' attribute
of the <outbound> element, e.g.
<interface type='bridge'>
...
<bandwidth>
<outbound average='10240'/>
</bandwidth>
</interface>
Also add a unit test to check the conversion logic.

The xen sexpr config format has long supported specifying vif rate
limiting, e.g.
(device

(rate '10240KB/s')
...
)
)
Add support for mapping rate to and from <bandwidth> in the xenconfig

Also add unit tests to check the conversion logic.
This patch benefits both the old xen driver and the libxl driver.
Both drivers gain support for vif bandwidth when converting to/from
domXML and xen-sxpr. In addition, the old xen driver will now be
able to handle vif 'rate' setting when communicating with xend.
memory_dirty_rate corresponds to dirty-pages-rate in QEMU and

My commit 674afcb09e moved computing the
default listen address from qemuMigrationPrepareAny to
qemuMigrationPrepareIncoming. However, I didn't notice listenAddress was
later passed to qemuMigrationStartNBDServer. Thus, it would be called
with the original value of listenAddress (NULL).
Let's add the updated listen address to qemuProcessIncomingDef and use
it when starting NBD servers.

Most of the changes to the list of active and inactive PCI devices
happen in virHostdev, where they are properly logged.
virPCIDeviceDetach() and virPCIDeviceReattach(), however, change the
inactive list as well, so they should be logging similar messages.
Instead of misusing a const string to hold up runtime allocated
data, introduce new variable @hoststr and obey const correctness.

If user defines a virtio channel with UNIX socket backend and doesn't
care about the path for the socket (e.g. qemu-agent channel), we still
generate it into the persistent XML. Moreover when then user renames
the domain, due to its persistent socket path saved into the per-domain
directory, it will not start. So let's forget about old generated paths
and also stop putting them into the persistent definition.

If no port number was provided for a storage pool libvirt defaults to
port 6789; however, librbd/librados already default to 6789 when no port
number is provided.
In the future Ceph will switch to a new port for the Ceph monitors since
port 6789 is already assigned to a different application by IANA.
Port 6789 is assigned to SMC-HTTPS and Ceph now has port 3300 assigned as
the 'Ceph monitor' port.
In this case it is the best solution to not hardcode any port number into
libvirt and let librados handle the connection.
Only if a user specifies a different port number we pass it down to librados,
otherwise we leave it blank.

It could happen that rbd_list() returns X names, but that while
refreshing the pool one of those RBD images is removed from Ceph
through a different route then libvirt.
We do not need to error out in such case, we can simply ignore the
volume and continue.
error : volStorageBackendRBDRefreshVolInfo:289 :
failed to open the RBD image 'vol-998': No such file or directory
It could also be that one or more Placement Groups (PGs) inside Ceph
are inactive due to a system failure.
If that happens it could be that some RBD images can not be refreshed
and a timeout will be raised by librados.
