When we migrate vms concurrently, there's a chance that libvirtd on
destination assigns the same port for different migrations, which will
lead to migration failure during prepare phase on destination. So we use
virPortAllocator here to solve the problem.

netcfStateInitialize() initializes the driverState variable,
and when netcfStateCleanup is called, it will call virReportError()
if driverState is NULL.
This is not consistent with what other state objects are doing,
they return -1 without reporting an error in such cases.

When I quit the process which only register VIR_DOMAIN_EVENT_ID_REBOOT,
I got error like:
"libvirt: XML-RPC error : internal error: domain event 0 not registered".
Then I add the following code, it fixed.

The header definition didn't match the function declaration, so adjusted
header to reflect the definition.
Found during a Coverity build where STATIC_ANALYSIS is enabled resulting
in the internal.h adding __nonnull__ handling to arguments.
Commit '6d264c91' added support for the qemuMonitorJSONDrivePivot() and
commit 'fbc3adc9' added a corresponding test which ended up triggering
the build failure which I didn't notice until today!
'--print-xml' option is very useful for doing some test.
But we had to specify a real domain for it.
This patch could enable us to specify a fake domain
when using --print-xml option.

The last argument of memmove is the amount of bytes to be moved. The
amount is in Bytes. We are moving some void pointers around. However,
since sizeof(void *) is not Byte on any architecture, we've got the
arithmetic wrong.
This patch improves the error checking in the LOCAL_PEERCRED version
of virNetSocketGetUNIXIdentity, used by FreeBSD and Mac OSX.
1. The error return paths now correctly unlock the socket. This is
implemented in exactly the same way as the SO_PEERCRED version,
using "goto cleanup"
2. cr.cr_ngroups is initialised to -1, and cr.cr_ngroups is checked
for negative and overlarge values.
This means that if the getsockopt() call returns success but doesn't
actually update the xucred structure, this is now caught. This
happened previously when getsockopt was called with SOL_SOCKET
instead of SOL_LOCAL, prior to commit 5a468b3, and resulted in
random uids being accepted.

prevent aclocal from preferring .m4 files under m4/ over the version
provided by gnulib, by using only one directory.
I have noticed this after './configure --help' gave me two different
versions of "--enable-threads". This was caused by aclocal that
preferred the version of lock.m4 provided by autopoint instead of
using the newer version distributed with gnulib.
Having two different directories made sense back when we checked
gnulib files into libvirt.git, but that was ages ago.

The recent patch series proposing the addition of PPC little endian
arch support to Linux defines new arch names 'ppcle' and 'ppc64le':
https://lists.ozlabs.org/pipermail/linuxppc-dev/2013-August/109908.html
This just makes libvirt know about these arch names, so it doesn't
immediately trip up if it seems these new names from uname.

This should resolve:
https://bugzilla.redhat.com/show_bug.cgi?id=924672
For BZ 924672 the problem stems from the fact that thin pool logical
volume devices show up in /sbin/lvs output just like normal logical
volumes do. Libvirt incorrectly assumes they are just normal logical
volumes and that they will have a corresponding /dev/vgname/lvname
device that has been created by udev and tries to use this device.
To illustrate here is an example of the /dev/vgname/ directory and
the lvs output for a normal lv, thin lv, and thin pool:
LV VG Attr LSize Pool Origin Data% Move Log Copy% Convert
lv vgguests -wi-a---- 1.00g
pool vgguests twi-a-tz- 11.00g 0.00
thinlv vgguests Vwi-a-tz- 1.00g pool 0.00
total 0
lrwxrwxrwx. 1 root root 7 Oct 8 19:35 lv -> ../dm-7
lrwxrwxrwx. 1 root root 7 Oct 8 19:37 thinlv -> ../dm-6
This patch modifies virStorageBackendLogicalMakeVol() to ignore thin pool
devices.
Some ancient gcc fails to see the variables are initialized in a
separate function and a false positive is produced:
