c2093b2aba Fix commit 29c1e913e4
This patch fixes changes done in commit 29c1e913e4
that was pushed without implementing review feedback.

The flag introduced by the patch is changed to VIR_DOMAIN_VCPU_GUEST and
documentation makes the difference between regular hotplug and this new
functionality more explicit.

The virsh options that enable the use of the new flag are changed to
"--guest" and the documentation is fixed too.

68eea85021 Fix ordering of file open in virProcessGetNamespaces
virProcessGetNamespaces() opens files in /proc/XXX/ns/ which will
later be passed to setns(). We have to make sure that the file
descriptors in the array are in the correct order. In particular
the 'user' namespace must be first otherwise setns() may fail
for other namespaces.

The order has been taken from util-linux's sys-utils/nsenter.c

Also we must ignore EINVAL in setns() which occurs if the
namespace associated with the fd, matches the calling process'
current namespace.

e463f4de77 Prefer VIR_STRDUP over virAsprintf(&dst, "%s", str)
There's no sense in using virAsprintf() just to duplicate a string.

ab7110bff6 Add support for VirtualBox 4.2 APIs
A few things have changed in the VirtualBox API - some small
(capitalizations of things in function names like Ip to IP
and Dhcp to DHCP) and some much larger (FindMedium is superceded
by OpenMedium). The biggest change for the sake of this patch
is the signature of CreateMachine is quite a bit different. Using
the Oracle source as a guide, to spin up a VM with a given UUID,
it looks like a text flag has to be passed in a new argument to
CreateMachine. This flag is built in the VirtualBox 4.2 specific
ifdefs and is kind of ugly but works. Additionally, there is now
(unused) VM groups support in CreateMachine and the previous
'osTypeId' arg is currently set to nsnull as in the Oracle code.

The FindMedium to OpenMedium changes were more straightforward
and are pretty clear. The rest of the vbox template changes are
basically spelling/capitalization changes from the looks of things.

e31b5cf393 qemu: Report the offset from host UTC for RTC_CHANGE event
https://bugzilla.redhat.com/show_bug.cgi?id=964177

Though both libvirt and QEMU's document say RTC_CHANGE returns
the offset from the host UTC, qemu actually returns the offset
from the specified date instead when specific date is provided
(-rtc base=$date).

It's not safe for qemu to fix it in code, it worked like that
for 3 years, changing it now may break other QEMU use cases.
What qemu tries to do is to fix the document:

http://lists.gnu.org/archive/html/qemu-devel/2013-05/msg04782.html

And in libvirt side, instead of replying on the value from qemu,
this converts the offset returned from qemu to the offset from
host UTC, by:

  /*
   * a: the offset from qemu RTC_CHANGE event
   * b: The specified date (-rtc base=$date)
   * c: the host date when libvirt gets the RTC_CHANGE event
   * offset: What libvirt will report
   */

  offset = a + (b - c);

The specified date (-rtc base=$date) is recorded in clock's def as
an internal only member (may be useful to exposed outside?).

Internal only XML tag "basetime" is introduced to not lose the
guest's basetime after libvirt restarting/reloading:

<clock offset='variable' adjustment='304' basis='utc' basetime='1370423588'/>

b0c3ee0c85 storage: Avoid unnecessary ternary operators and refactor the code
Setting of local variables in virStorageBackendCreateQemuImgCmd was
unnecessarily cluttered with ternary operators and repeated testing of
of conditions.

This patch refactors the function to use if statements and improves
error reporting in case inputvol is specified but does not contain
target path. Previously we would complain about "unknown storage vol
type 0" instead of the actual problem.

e5fa9db17e qemu: Reformat listen address prior to checking
Currently, a listen address for a SPICE server can be specified. Later,
when the domain is migrated, we need to relocate the graphics which
involves telling new destination to the SPICE server. However, we can't
just assume the listen address is the new location, because the listen
address can be ANYCAST (0.0.0.0 for IPv4, :: for IPv6). In which case,
we want to pass the remote hostname. But there are some troubles with
ANYCAST. In both IPv4 and IPv6 it has many ways for specifying such
address. For instance, in IPv4: 0, 0.0, 0.0.0, 0.0.0.0.  The number of
variations gets bigger in IPv6 world. Hence, in order to check for
ANYCAST address sanely, we should take the provided listen address,
parse it and format back in it's full form. Which is exactly what this
patch does.

922ebe4ead Ensure non-root can read /proc/meminfo file in LXC containers
By default files in a FUSE mount can only be accessed by the
user which created them, even if the file permissions would
otherwise allow it. To allow other users to access the FUSE
mount the 'allow_other' mount option must be used. This bug
prevented non-root users in an LXC container from reading
the /proc/meminfo file.

0ec376c20a nwfilter: grab driver lock earlier during init (bz96649)
This patch is in relation to Bug 966449:

https://bugzilla.redhat.com/show_bug.cgi?id=966449

This is a patch addressing the coredump.

Thread 1 must be calling  nwfilterDriverRemoveDBusMatches(). It does so with
nwfilterDriverLock held. In the patch below I am now moving the
nwfilterDriverLock(driverState) further up so that the initialization, which
seems to either take a long time or is entirely stuck, occurs with the lock
held and the shutdown cannot occur at the same time. 

Remove the lock in virNWFilterDriverIsWatchingFirewallD to avoid
double-locking.
