In order to track a block copy job across libvirtd restarts, we
need to save internal XML that tracks the name of the file
holding the mirror. Displaying this name in dumpxml might also
be useful to the user, even if we don't yet have a way to (re-)
start a domain with mirroring enabled up front. This is done
with a new <mirror> sub-element to <disk>, as in:
<disk type='file' device='disk'>
<driver name='qemu' type='raw'/>
<source file='/var/lib/libvirt/images/original.img'/>
<mirror file='/var/lib/libvirt/images/copy.img' format='qcow2' ready='yes'/>
...
</disk>
For now, the element is output-only, in live domains; it is ignored
when defining a domain or hot-plugging a disk (since those contexts
use VIR_DOMAIN_XML_INACTIVE in parsing). The 'ready' attribute appears
when libvirt knows that the job has changed from the initial pulling
phase over to the mirroring phase, although absence of the attribute
is not a sure indicator of the current phase. If we come up with a way
to make qemu start with mirroring enabled, we can relax the xml
restriction, and allow <mirror> (but not attribute 'ready') on input.
Testing active-only XML meant tweaking the testsuite slightly, but it
was worth it.

A "ide-drive" device can be either a hard disk or a CD-ROM,

When building on Fedora 17 (which uses gcc 4.7.0) with -O0 in CFLAGS,
three of the tests failed to compile.
cputest.c and qemuxml2argvtest.c had non-static structs defined
inside the macro that was being repeatedly invoked. Due to some so-far
unidentified change in gcc, the stack space used by variables defined
inside { } is not recovered/re-used when the block ends, so all these
structs have become additive (this is the same problem worked around
in commit cf57d345b). Fortunately, these two files could be fixed with
a single line addition of "static" to the struct definition in the
macro.
virnettlscontexttest.c was a bit different, though. The problem structs
in the do/while loop of macros had non-constant initializers, so it
took a bit more work and piecemeal initialization instead of member
initialization to get things to be happy.
In an ideal world, none of these changes should be necessary, but not
knowing how long it will be until the gcc regressions are fixed, and
since the code is just as correct after this patch as before, it makes
sense to fix libvirt's build for -O0 while also reporting the gcc
problem.

rpm builds for i686 were failing with a segfault in
networkxml2argvtest. Running under valgrind showed that a region of
memory was being referenced after it had been freed (as the result of
realloc - see the valgrind report in the BZ).
The problem (in replaceTokens() - added in commit 22ec60, meaning this
bug was in 0.9.10 and 0.9.11) was that the pointers token_start and
token_end were being computed based on the value of *buf, then *buf
was being realloc'ed (potentially moving it), then token_start and
token_end were used without recomputing them to account for movement
of *buf.
The solution is to change the code so that token_start and token_end
are offsets into *buf rather than pointers. This way there is only a
single pointer to the buffer, and nothing needs readjusting after a
realloc. (You may note that some uses of token_start/token_end didn't
need to be changed to add in "*buf +" - that's because there ended up
being a +*buf and -*buf which canceled each other out).
DV gets the credit for finding this bug and pointing out the valgrind
report.
Some of the test suites use fprintf with format specifiers
that are not supported on Win32 and are not fixed by gnulib.
The mingw32 compiler also has trouble detecting ssize_t

cast to size_t to avoid this problem

XenD-3.1 introduced managed domains. HV-domains have rtc_timeoffset
(hgd24f37b31030 from 2007-04-03), which tracks the offset between the
hypervisors clock and the domains RTC, and is persisted by XenD.
In combination with localtime=1 this had a bug until XenD-3.4
(hg5d701be7c37b from 2009-04-01) (I'm not 100% sure how that bug
manifests, but at least for me in TZ=Europe/Berlin I see the previous
offset relative to utc being applied to localtime again, which manifests
in an extra hour being added)
XenD implements the following variants for clock/@offset:
- PV domains don't have a RTC → 'localtime' | 'utc'
- <3.1: no managed domains → 'localtime' | 'utc'
- ≥3.1: the offset is tracked for HV → 'variable'
due to the localtime=1 bug → 'localtime' | 'utc'
- ≥3.4: the offset is tracked for HV → 'variable'
Current libvirtd still thinks XenD only implements <clock offset='utc'/>
and <clock offset='localtime'/>, which is wrong, since the semantic of
'utc' and 'localtime' specifies, that the offset will be reset on
domain-restart, while with 'variable' the offset is kept. (keeping the
offset over "virsh edit" is important, since otherwise the clock might
jump, which confuses certain guest OSs)
xendConfigVersion was last incremented to 4 by the xen-folks for
xen-3.1.0. I know of no way to reliably detect the version of XenD
(user space tools), which may be different from the version of the
hypervisor (kernel) version! Because of this only the change from
'utc'/'localtime' to 'variable' in XenD-3.1 is handled, not the buggy
behaviour of XenD-3.1 until XenD-3.4.
For backward compatibility with previous versions of libvirt Xen-HV
still accepts 'utc' and 'localtime', but they are returned as 'variable'
on the next read-back from Xend to libvirt, since this is what XenD
implements: The RTC is NOT reset back to the specified time on next
restart, but the previous offset is kept.
This behaviour can be turned off by adding the additional attribute
adjustment='reset', in which case libvirt will report an error instead
of doing the conversion. The attribute can also be used as a shortcut to
offset='variable' with basis='...'.
With these changes, it is also necessary to adjust the xen tests:
"localtime = 0" is always inserted, because otherwise on updates the
value is not changed within XenD.
adjustment='reset' is inserted for all cases, since they're all <
XEND_CONFIG_VERSION_3_1_0, only 3.1 introduced persistent
rtc_timeoffset.
Some statements change their order because code was moved around.

Since Xen 3.1 the clock=variable semantic is supported. In addition to
qemu/kvm Xen also knows about a variant where the offset is relative to
'localtime' instead of 'utc'.
Extends the libvirt structure with a flag 'basis' to specify, if the
offset is relative to 'localtime' or 'utc'.
Extends the libvirt structure with a flag 'reset' to force the reset
behaviour of 'localtime' and 'utc'; this is needed for backward
compatibility with previous versions of libvirt, since they report
incorrect XML.

Extend the RelaxNG schema accordingly.

When qparams support was dropped in commit bc1ff160, we forgot

numad is an user-level daemon that monitors NUMA topology and
processes resource consumption to facilitate good NUMA resource
alignment of applications/virtual machines to improve performance
and minimize cost of remote memory latencies. It provides a
pre-placement advisory interface, so significant processes can
be pre-bound to nodes with sufficient available resources.
More details: http://fedoraproject.org/wiki/Features/numad
"numad -w ncpus:memory_amount" is the advisory interface numad
provides currently.
This patch add the support by introducing a new XML attribute
for <vcpu>. e.g.
<vcpu placement="auto">4</vcpu>
<vcpu placement="static" cpuset="1-10^6">4</vcpu>
The returned advisory nodeset from numad will be printed
in domain's dumped XML. e.g.
<vcpu placement="auto" cpuset="1-10^6">4</vcpu>
If placement is "auto", the number of vcpus and the current
memory amount specified in domain XML will be used for numad
command line (numad uses MB for memory amount):
numad -w $num_of_vcpus:$current_memory_amount / 1024
The advisory nodeset returned from numad will be used to set
domain process CPU affinity then. (e.g. qemuProcessInitCpuAffinity).
If the user specifies both CPU affinity policy (e.g.
(<vcpu cpuset="1-10,^7,^8">4</vcpu>) and placement == "auto"
the specified CPU affinity will be overridden.
Only QEMU/KVM drivers support it now.
See docs update in patch for more details.
If there is a disk file with a comma in the name, QEmu expects a double
comma instead of a single one (e.g., the file "virtual,disk.img" needs
to be specified as "virtual,,disk.img" in QEmu's command line). This
patch fixes libvirt to work with that feature. Fix RHBZ #801036.

We found few more AMD-specific features in cpu64-rhel* models that
made it impossible to start qemu guest on Intel host (with this
setting) even though qemu itself starts correctly with them.
This impacts one test, thus the fix in tests/cputestdata/.
One of the recent commits introduced support for
spice agent-mouse. However, test for this feature
require some tweaking: pass QEMU_CAPS_CHARDEV_SPICEVMC |
QEMU_CAPS_NODEFCONFIG and add "-vga cirrus".
If user hasn't supplied any tlsPort we default to setting it
to zero in our internal structure. However, when building command
line we test it against -1 which is obviously wrong.
