88f3f7c390 conf: storage: Add volume feature formatter for gluster pools
Libvirt didn't output feature flags for images stored on native gluster.
Fix this trivially by adding a feature formatter callback.

fb62d31151 build: link libvirt_conf with libxml
Since there is code using functions from the libxml library,
libvirt_conf should have that in LIBADD so it can be linked against
even without libvirt_util (which usually deals with the error itself,
since libvirt_util has libxml in LIBADD).  The same applies to
storage_backend.c.

7315189ec0 vboxsnapshotxmltest: Don't write to a file in abs_srcdir
In the test, the snapshot XML is written into a file that's located
under:

  abs_srcdir/vboxsnapshotxmldata/testResult.vbox

However, the abs_srcdir doesn't have to be necessarily writable. It
should have been abs_builddir instead. Moreover, the label in the func
creating the file is called 'fail' while it fulfils the duty of
'cleanup' label.

e5f5805f62 securityselinuxlabeltest: Don't create dummy file in the srcdir
At the very beginning of the test we check if the underlying
filesystem supports extended attributes as they are used to store fake
SELinux labels. In order to check that, a dummy file is created and
semi-random attribute is set. However, the file is created under:

  abs_srcdir "/securityselinuxlabeldata/testxattr"

which has two problems: abs_srcdir is not required to be writable, so
it should have been abs_builddir. The second one is - there's no
"securityselinuxlabeldata" folder under abs_builddir. The problem was
introduced in caf164f1.

1c7601f5c3 Report one error less when getting net dev speed
virFileReadAll already logs an error. If reading the 'speed' file
fails with EINVAL, we log an error even though we ignore it. If it
fails with other errors, we log two errors.

Use virFileReadAllQuiet - ignore EINVAL and report just one error
in other cases.

Fixes this error on libvirtd startup:

ec7b922576 libxl: add PV console if not explicitly specified
Xen PV domains always have a PV console, so add one to the domain
config via post-parse callback if not explicitly specified in
the XML.  The legacy Xen driver behaves similarly, causing a
regression when switching to the new Xen toolstack.  I.e.

  virsh console pv-domain

will no longer work after upgrading a xm/xend stack to xl/libxl.

bfc72e9992 libxl: don't break the build on Xen>=4.5 because of libxl_vcpu_setaffinity()
libxl interface for vcpu pinning is changing in Xen 4.5. Basically,
libxl_set_vcpuaffinity() now wants one more parameter. That is
representative of 'VCPU soft affinity', which libvirt does not use.

To mark such change, the macro LIBXL_HAVE_VCPUINFO_SOFT_AFFINITY is
defined. Use it as a gate and, if present, re-#define the calls from
the old to the new interface, to avoid breaking the build.

9036b31aed qemu: snapshot: Save persistent domain config when taking external snapshot
Commit 55bbb011b9 introduced a regression
where we forgot to save the persistent domain configuration after an
external snapshot. This would make libvirt forget the snapshots and
effectively revert to the previous state in the following scenario:

1) Start VM
2) Take snapshot
3) Destroy VM
4) Restart libvirtd

Also fix spurious blank line added by patch mentioned above.

of those functions would return data the same way, so making @mac an

caf164f1e4 test: add user_xattr check for securityselinuxlabeltest
libvirt unit test used setxattr with "user.libvirt.selinux" name to
emulate setfilecon of selinux. But for some old kernel filesystem
(like 2.6.32-431.el6.x86_64), if the filesystem is not mounted with
user_xattr flag, the setxattr with "user.libvirt.selinux" will fail.

So adding testUserXattrEnabled() in securityselinuxlabeltest.c,
if user_xattr is not enabled, skip this case.

The user_xattr is departed in newer kernel, therefore this commit is
only for the compatablity for old kernel.

9b291bbe20 docs: publish correct enum values
We publish libvirt-api.xml for others to use, and in fact, the
libvirt-python bindings use it to generate python constants that
correspond to our enum values.  However, we had an off-by-one bug
that any enum that relied on C's rules for implicit initialization
of the first enum member to 0 got listed in the xml as having a
value of 1 (and all later members of the enum were equally
botched).

The fix is simple - since we add one to the previous value when
encountering an enum without an initializer, the previous value
must start at -1 so that the first enum member is assigned 0.

The python generator code has had the off-by-one ever since DV
first wrote it years ago, but most of our public enums were immune
because they had an explicit = 0 initializer.  The only affected
enums are:
- virDomainEventGraphicsAddressType (such as
VIR_DOMAIN_EVENT_GRAPHICS_ADDRESS_IPV4), since commit 987e31e
(libvirt v0.8.0)
- virDomainCoreDumpFormat (such as VIR_DOMAIN_CORE_DUMP_FORMAT_RAW),
since commit 9fbaff0 (libvirt v1.2.3)
- virIPAddrType (such as VIR_IP_ADDR_TYPE_IPV4), since commit
03e0e79 (not yet released)

Thanks to Nehal J Wani for reporting the problem on IRC, and
for helping me zero in on the culprit function.

39931f5ee8 qemu: fix guestfwd chardev option back how it was
Since commit d86c876a66 we are using
guestfwd=tcp:IP:PORT,chardev=ID for guestfwd specification, however,
that has not changed in qemu, so guestfwd does not work since.

Apart from that, guestfwd is not working with older qemu that doesn't
have QEMU_CAPS_DEVICE.

Both regressions exist since late 2009 and nobody found that (until
now), so I'm only fixing the first one.

error for incompatible CPUs and the reason will be described in the
