The storage pool's management doesn't relate with a domain, it
probably was an intention, but not achieved yet. And the fact
is only active pools are listed by default.

tools/virsh.c: New helper function vshStringToArray.
tools/virsh.h: Declare vshStringToArray.
tools/virsh-domain.c: use the helper in cmdUndefine.

src/test/test_driver.c: Implement listAllStoragePools

src/storage/storage_driver.c: Implement listAllStoragePools.

The RPC generator doesn't support returning list of object, this patch does
the work manually.

  * daemon/remote.c:
    Implement the server side handler remoteDispatchConnectListAllStoragePools

  * src/remote/remote_driver.c:
    Add remote driver handler remoteConnectListAllStoragePools.

  * src/remote/remote_protocol.x:

    structs to represent the args and ret for it.

  * src/remote_protocol-structs: Likewise.

src/conf/storage_conf.c: Add virStoragePoolMatch to filter the
pools; Add virStoragePoolList to iterate over the pool objects
with filter.

src/conf/storage_conf.h: Declare virStoragePoolMatch,
virStoragePoolList, and the macros for filters.

src/libvirt_private.syms: Export helper virStoragePoolList.

This introduces a new API to list the storage pool objects,
4 groups of flags are provided to filter the returned pools:

  * Active or not

  * Autostarting or not

  * Persistent or not

  * And the pool type.

include/libvirt/libvirt.h.in: New enum virConnectListAllStoragePoolFlags;
                              Declare the API.

ESX doesn't use the common virDomainObj implementation so this patch
adds a separate implementation.

This driver supports all currently defined filtering flags, but as with
other drivers some combinations yield a empty result list.

Hyperv doesn't use the common virDomainObj implementation so this patch
adds a separate implementation.

This driver supports all currently added flags for filtering although
some of those don't make sense with this driver (no support yet) and
thus produce no output when used.

On systems without cyrus-sasl-devel available (I happened to be
in that situation on my FreeBSD testing), this test fails rather
miserably:

TEST: libvirtdconftest
      .....!!!!!!...!!!!!!!!!!!!!!!!!!!!!!!!!  39  FAIL
FAIL: libvirtdconftest

with verbose output showing things like:

39) Test corruption                                          ... libvir: Config File error : unsupporeted configuration: remoteReadConfigFile: /usr/home/dummy/libvirt/tests/../daemon/libvirtd.conf: auth_tcp: unsupported auth sasl

I tested both OpenBSD and cygwin; both failed 'make check' with:

  GEN    check-symfile
Can't return outside a subroutine at ./check-symfile.pl line 13.

Perl requires 'exit 77' instead of 'return 77' in that context,
but even with that tweak, the build still fails, since the exit
code of 77 is only special to explicit TESTS=foo listings, and
not to make-only dependency rules where we are not going through
automake's test framework.

* src/check-symfile.pl: Kill bogus platform check...
* src/Makefile.am (check-symfile): ...and replace with an automake
conditional.

If a network or interface is configured to use Open vSwitch, but
ovs-vswitchd (the Open vSwitch database service) isn't running, the
ovs-vsctl add-port/del-port commands will hang indefinitely rather
than returning an error. There is a --nowait option, but that appears
to have no effect on add-port and del-port commands, so instead we add
a --timeout=5 to the commands - they will retry for up to 5 seconds,
then fail if there is no response.

A previous patch forced libnl-3 and netcf-0.2.2 (which itself requires
libnl-3) when *building* for Fedora 18+ (and RHEL 7+), but the
install-time Requires: for netcf has always been implicit due to
libvirtd linking with libnetcf.so. However, the since the API of netcf
didn't change when it was rebuilt to use libnl-3, the internal library
version didn't change either, making it possible (from rpm's point of
view) to upgrade libvirt without upgrading netcf (in reality, that
leads to a segfault - see
https://bugzilla.redhat.com/show_bug.cgi?id=853381).

The solution is to put an explicit Requires: line in libvirt's
specfile for fedora >= 18 and rhel >= 7.

On a machine without xsltproc, the build failed with:

OpenBSD ships with gcc 4.2.1, which annoyingly treats all format
strings as though they were also attribute((nonnull)).  The two
concepts are orthogonal, though, as evidenced by the number of
spurious warnings it generates on uses where we know that
virReportError specifically handles NULL instead of a format
string; worse, since we now force -Werror on git builds, it
prevents development builds on OpenBSD.

I hate to do this, as it disables ALL format checking on older
gcc, and therefore misses out on some useful checks (code that
happened to compile on Linux may still have type mismatches
when compiled on other platforms, as evidenced by the number
of times I have fixed formatting mismatches for uid_t as found
by warnings on Cygwin), but I don't see any other way to keep
-Werror alive and still compile on OpenBSD.

A more invasive change would be to make virReportError() mark
its format attribute as nonnull, and fix (a lot of) fallout;
we may end up doing that anyways as part of danpb's error
refactoring improvements, but not today.

* src/internal.h (ATTRIBUTE_FMT_PRINTF): Use preferred spellings.
* m4/virt-compile-warnings.m4 (-Wformat): Disable on older gcc.

This is another fix for the emulator-pin series. When going through
the cputune pinning settings, the current code is trying to pin all
the CPUs, even when not all of them are specified. This causes error
in the subsequent function which, of course, cannot find the cpu to
pin. Since it's enough to pass the correct VCPU ID to the function,
the fix is trivial.

Based on the similar gnulib commit 96ad9077.  The use of
$(_sc_search_regexp) already injects $(ME) into any output
messages, so a failure of these rules would look like this,
pre-patch:

maint.mk: maint.mk: use virStrToLong_*, not strtol variants

* cfg.mk (sc_prohibit_strncmp, sc_prohibit_strtol)
(sc_libvirt_unmarked_diagnostics): Drop redundant $(ME).

Yesterday's commit 15d2c9fa pointed out that virsh was still using
localtime(), which is not thread-safe, even though virsh is
definitely multi-threaded.  Even if we only ever triggered it from
one thread, it's better safe than sorry for maintenance purposes.

* cfg.mk (exclude_file_name_regexp--sc_prohibit_nonreentrant):
Tighten the rule.
* tools/virsh.c (vshOutputLogFile): Avoid localtime.
(vshEditWriteToTempFile, vshEditReadBackFile, cmdCd, cmdPwd)
(vshCloseLogFile): Avoid strerror.
* tools/console.c (vshMakeStdinRaw): Likewise.
* tools/virsh-domain.c (vshGenFileName): Fix spacing in previous
patch.

The libvirt storage driver uses librbd.so for its functionality.
RPM will automatically add a dependency on the library, so there
is no need to have an explicit dependency on the ceph RPM itself.
This allows newer Fedora distros to avoid pulling in the huge
ceph RPM, in favour of just having the libraries installed

Only VNC_{{DIS,}CONNECTED,INITIALIZED} and SPICE_INITIALIZED events are
documented to support server/auth field and even there it is marked as
optional. Emit "" auth scheme in case QEMU didn't send it.

As a request was raised for this, I added few lines in the "Notes"
part of the "security_driver" comments about allowed values.

Most likely this problem arose because of the patch I pushed
in gnulib commit e07d7c40f3ca5ec410cf5aa6fa03cfe51e712039.
Previously, gnulib required timeval's tv_sec to be
the same size as time_t.  But now, it requires only that
tv_sec be big enough to hold a time_t.

This patch was needed for Emacs.  Without the patch, gnulib
replaced struct timeval on OpenBSD, and this messed up
utimens.c, and Emacs wouldn't build.

Alternatively, gnulib could substitute its own struct timeval
for the system's, wrapping every struct timeval-using function
(gettimeofday, futimesat, futimes, lutimes, etc.  That'd be
more work, though.  And it would introduce some performance
issues with gettimeofday, which is supposed to be fast.

I've been trying to get away from using struct timeval,
and to use the higher-resolution struct timespec instead,
so messing with these obsolescent interfaces has been
lower priority for me.  But if someone wants to take the
more-ambitious approach that'd be fine, I expect.

For this particular case, though, how about if we avoid
the problem entirely?  libvirt doesn't need to use struct
timeval here at all.  It makes libvirt smaller and probably
faster, and it ports to OpenBSD without messing with gnulib.

On OpenBSD, clock_gettime() exists in libc rather than librt, and
blindly linking with -lrt made the build fail.  Gnulib already
did the work for determining which libraries to use, so we should
reuse that work rather than doing it ourselves.

* bootstrap.conf (gnulib_modules): Pull in clock-time.
* configure.ac (RT_LIBS): Drop.
* src/Makefile.am (libvirt_util_la_LIBADD): Use gnulib variable
instead.
* src/util/virtime.c (includes): Simplify.

After discussion with DB we decided to rename the new iolimit
element as it creates the impression it would be there to
limit (i.e. throttle) I/O instead of specifying immutable
characteristics of a block device.
This is also backed by the fact that the term I/O Limits has
vanished from newer storage admin documentation.

When reboot using qemu guest agent was requested, qemu driver kept
waiting for SHUTDOWN event from qemu. However, such event is never
emitted during guest reboot and qemu driver would keep waiting forever.

The viratomictest.c was casting from an int to a void* via a
long. This works on Linux or Mingw32, but fails on Mingw64
due to a pointer/integer size mis-match. Replacing 'long'
with 'intptr_t' ensures matching type sizes

When the password change failed we updated the graphic definition
anyways, which is not desired.

Few tests were added which are checking whether the parsing of the xml
and command-line arguments is working and compatible with each other.

This patch adds support for running qemu guests with the required
parameters to forcefully enable or disable BIOS advertising of S3 and
S4 states.  The support for this is added to capabilities and there is
also a qemu command parameter parsing implemented.

There is a new <pm/> element implemented that can control what ACPI
sleeping states will be advertised by BIOS and allowed to be switched
to by libvirt. The default keeps defaults on hypervisor, otherwise
forces chosen setting.
The documentation of the pm element is added as well.

A user reported this crash when using python bindings:

In the python bindings, returning NULL makes python think an
exception was thrown, while returning the None object lets the
wrappers know that a libvirt error exists.

Without this patch, logged command executions can be ambiguous if
the command contained any shell metacharacters.  This has caused
more than one person to attempt to patch clients to add unnecessary

correct args, and only the logged output was ambiguous.

Now that vshCommandRun() checks for the connection automaticaly, remove
all of the redundant checks in the code.

vshConnectionUsability() no longer needs to be exported and this patch
marks it static.

Almost each virsh command uses the function vshConnectionUsability
before doing anything, to check if the connection is "alive".  Commands
that don't need an conection are already conveniently marked with
VSH_CMD_FLAG_NOCONNECT. We can automaticaly check for the connection
before calling any remote command so we don't forget to do so.

This patch also upgrades the connection check to use virConnectIsAlive
along with the current approach.

After fixing the last review comments on remote port searching (commit
a14b4aea), the commit right after that
wasn't modified accordingly, therefore two values weren't changed as
they should and the configurable ports don't work as expected.

This simple commit changes last two values missed and fixes the issue.
