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.

02bffd47bd net: merge virNetworkGetDHCPLeases and virNetworkGetDHCPLeasesForMAC
Instead of maintaining two very similar APIs, add the "@mac" parameter
to virNetworkGetDHCPLeases and kill virNetworkGetDHCPLeasesForMAC. Both
of those functions would return data the same way, so making @mac an
optional filter simplifies a lot of stuff.

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.

values.

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.

b14954fc12 cpuCompare*: Add support for reporting failure on incompatible CPUs
When CPU comparison APIs return VIR_CPU_COMPARE_INCOMPATIBLE, the caller
has no clue why the CPU is considered incompatible with host CPU. And in
some cases, it would be nice to be able to get such info in a client
rather than having to look in logs.

To achieve this, the APIs can be told to return VIR_ERR_CPU_INCOMPATIBLE
error for incompatible CPUs and the reason will be described in the
associated error message.
