0104c43195 tests: add helper for VIR_TEST_REGENERATE_OUTPUT flag
When this flag is specified, some of the expected output files will be
regenerated with the actual output data.  Use helper function like for
other flags.

This patch partially reverts previous commit 91a00424 and moves the post
parse function to xenParseSxpr.  This update is required because xen

f87668b70e qemu: Fix NBD migration with default listenAddress
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.

4e1f37f812 pci: Log debug messages when manipulating the inactive list
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.

7140807917 qemu: Don't bother user with libvirt-internal paths
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.

6343018fac rbd: Do not append Ceph monitor port number 6789 if not provided
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.

f46d137e33 rbd: Do not error out on a single image during pool refresh
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.

  error : volStorageBackendRBDRefreshVolInfo:289 :
    failed to open the RBD image 'vol-893': Connection timed out

d7db33bfe9 qemu: Specify format= iff disk source is not empty
Just recently, qemu forbade specifying format for sourceless
disks (qemu commit 39c4ae941ed992a3bb5). It kind of makes sense.
If there's no file to open, why specify its format. Anyway, I
have a domain like this:

    <disk type='file' device='cdrom'>
      <driver name='qemu' type='raw'/>
      <target dev='hda' bus='ide'/>
      <readonly/>
      <address type='drive' controller='0' bus='0' target='0' unit='0'/>
    </disk>

and obviously I am unable to start it. Therefore, a fix on our
side is needed too.

79e7872530 docs: update to properly reflect meaning of fields in log filter
The documentation (and comment in libvirtd.conf) says that the text in
a log filter is compared to the "source file name", and gives the
example of "util/json", but this is not correct (at least not since
commit 2835c1e, possibly earlier). It is instead compared to the
string given in the VIR_LOG_INIT() macro invocation at the top of each
source file, which is always "similar to but not the same as" the
source file name (in the example above, the proper name is
"util.json", while the file name is "util/virjson.c"). This patch
corrects the misstatement in both the documentation and in
libvirtd.conf.

If we're replacing the NBD data, it's simplest to free the old object
(including the disk list) and allocate a new one.

If no matching block job is found, qemuMonitorGetBlockJobInfo returns 0
and we should not write anything to the caller-supplied
virDomainBlockJobInfo pointer.

7bf3c13d9c tools: Disable virt-login-shell on mingw
So, after bec787ee9d we are building virt-login-shell
independent of LXC driver. This is nice, but the binary is
enabled by default which makes no sense on mingw. In fact, it
triggers some compilation errors there:

  CC       virt_login_shell-virt-login-shell.o
../../tools/virt-login-shell.c: In function 'main':
../../tools/virt-login-shell.c:289:15: error: implicit declaration of function 'sysconf' [-Werror=implicit-function-declaration]
     openmax = sysconf(_SC_OPEN_MAX);
               ^
../../tools/virt-login-shell.c:289:5: error: nested extern declaration of 'sysconf' [-Werror=nested-externs]
     openmax = sysconf(_SC_OPEN_MAX);
     ^
../../tools/virt-login-shell.c:289:23: error: '_SC_OPEN_MAX' undeclared (first use in this function)
     openmax = sysconf(_SC_OPEN_MAX);
                       ^
../../tools/virt-login-shell.c:289:23: note: each undeclared identifier is reported only once for each function it appears in
cc1: all warnings being treated as errors

While we could workaround sysconf(_SC_OPEN_MAX) issue, the binary
itself makes no sense on systems where no LXC can be spawned.

f55d1316ad sysconf: Include unistd.h
The manpage for sysconf() suggest including unistd.h as the
function is declared there. Even though we are not hitting any
compile issues currently, let's include the correct header file
instead of relying on some hidden include chain.

eec91958b4 virStorageVolWipe: Document that wiping journaled FS is useless
So you have a libvirt volume that you want to wipe out. But lets
say that the volume is actually a file stored on a journaled
filesystem. Overwriting it with zeroes or a pattern does not mean
that corresponding physical location on the disk is overwritten
too, due to journaling. It's the same story with network based
volumes, copy-on-write filesystems, and so on. Since there is no
way that an userland application can write onto specific areas on
disk, all that we can do is document the fact.

635daa2556 vz: BUG: fix connecting hang in case of init failure
In case of prlsdkLoadDomains fails, vzOpenDefault should
clear connection privateData pointer every time its
memory is actually freed.
Also it is not necessary to call vzConnectClose if a call
to vzOpenDefault fails, because they both make cleanup of
connection privateData.

53a15aed39 qemu: Process new 'append' attribute for char dev with output to a file
By default, QEMU truncates serial file on open. Sometimes, it could be weird -
for example, when we are trying to investigate some event, which occured several
restarts ago. This patch adds an ability to preserve previous content.

when it is made after first one fails by some reason, and
