The name is confusing, and there are just two uses: one is a test case,
and the other will be removed as part of an upcoming refactoring of
the hostdev code.
The current code was a little bit odd. At first we've removed all
possible implicit input devices from domain definition to add them later
back if there was any graphics device defined while parsing XML
description. That's not all, while formating domain definition to XML
description we at first ignore any input devices with bus different to
USB and VIRTIO and few lines later we add implicit input devices to XML.
This seems to me as a lot of code for nothing. This patch may look
to be more complicated than original approach, but this is a preferred
way to modify/add driver specific stuff only in those drivers and not
deal with them in common parsing/formating functions.
The update is to add those implicit input devices into config XML to
follow the real HW configuration visible by guest OS.
There was also inconsistence between our behavior and QEMU's in the way,
that in QEMU there is no way how to disable those implicit input devices
for x86 architecture and they are available always, even without graphics
device. This applies also to XEN hypervisor. VZ driver already does its
part by putting correct implicit devices into live XML.

A future patch will refactor the storage of the pinning information in a
way where the ordering will be lost. Order them numerically to avoid
changing the tests later.
Make bhyveload respect boot order as specified by os.boot section of the
domain XML or by "boot order" for specific devices. As bhyve does not
support a real boot order specification right now, it's just about
choosing a single device to boot from.
... and consolidate the cmdline/extra/root parsing to facilitate doing
so.
The logic is the same as xl's parse_cmdline from the current xen.git master
branch (e6f0e099d2c17de47fd86e817b1998db903cab61).
On the formatting side switch to producing cmdline= instead of extra=.
Update a few tests and add serveral more.
- test-cmdline is added to test the exclusive use of cmdline.
- test-fullvirt-direct-kernel-boot.cfg is updated due to the switch
on the formatting side and now tests the exclusive use of cmdline=.
- Tests are added for both paravirt and fullvirt where the .cfg uses
extra= and (paravirt only) root=. These are format (xl->xml) only
since the inverse will generate cmdline= hence is not a round trip
(which was already true if using root=, which used to generate
extra= on the way back).
- Tests are added for both paravirt and fullvirt where the .cfg
declares cmdline= as well as bogus extra= and (paravirt only) root=
entries which should be ignored. Again these are format only tests
since the inverse won't include the bogus lines.
The last two bullets here required splitting the DO_TEST macro into
two halves, as is done in the xmconfigtest.c case.

Add a new storage pool source device attribute 'part_separator=[yes|no]'
in order to allow a 'disk' storage pool using a device mapper multipath
device to not add the "p" partition separator to the generated device
name when libvirt_parthelper is run.
This will allow libvirt to find device mapper multipath devices which were
configured in /etc/multipath.conf to use 'user_friendly_names' or custom
'alias' names for the LUN.

Autodeflate cannot be enabled/disabled for running domain.
Use virDomainDefAddUSBController() to add an EHCI1+UHCI1+UHCI2+UHCI3
controller set to newly defined Q35 domains that don't have any USB
controllers defined.
The real Q35 machine puts the first USB controller set (EHCI+(UHCIx4))
on bus 0 slot 0x1D, and the 2nd USB controller set on bus 0 slot 0x1A,
so let's attempt to make the virtual machine match that for
controllers with auto-assigned addresses when possible.
Three test cases were added to assure that the proper addresses are
assigned - one with a single set of unaddressed USB controllers, one
with 3 (to grab both preferred slots plus one more), and one with the
order of the controller definitions reordered, to assure that the
auto-assignment isn't mixed up by order.
If the q35 specific disable s3/s4 setting isn't supported, fallback to
specifying the PIIX setting, which is the previous behavior. It doesn't
have any effect, but qemu will just warn about it rather than error:
qemu-system-x86_64: Warning: global PIIX4_PM.disable_s3=1 not used
qemu-system-x86_64: Warning: global PIIX4_PM.disable_s4=1 not used
Since it doesn't error, I don't think we should either, since there
may be configs in the wild that already have q35 + disable_s3/4 (via
virt-manager)
The condition was checking for UHCI (and OHCI for ppc64) availability so
that it can specify the proper device instead of legacy usb. However,
for ppc64, we don't need to check both OHCI and UHCI, but only OHCI as
that is the legacy default. The condition is so big that it was just a
matter of time when someone will make a mistake there, so let's use more
lines so that it is visible what the condition checks for.
This fixes usage of -device instead of -usb for ppc64 that supports
pci-usb-ohci and does not support piix3-usb-uhci.

Future changes will make some of these tests dependent on specific
QEMUCaps flags, so wire up the basic handling. Flags will be added
in future patches.
For the standard active/inactive XML testing, if we leave the file loading
up to the generic XML2XML infrastructure, we get the benefit of
VIR_TEST_REGENERATE_OUTPUT, at the price of a few more disk reads. Seems
worth it.
Since test files are formatted predictably nowadays, we can make
VIR_TEST_REGENERATE_OUTPUT handle most cases for us with a simple
replacement. test-wrap-argv.pl is still canon, but this bit makes
it easier to confirm test output changes during active development.

xend prior to 4.0 understands vcpus as maxvcpus and vcpu_avail
as a bit map of which cpus are online (default is all).
xend from 4.0 onwards understands maxvcpus as maxvcpus and
vcpus as the number which are online (from 0..N-1). The
upstream commit (68a94cf528e6 "xm: Add maxvcpus support")
claims that if maxvcpus is omitted then the old behaviour
(i.e. obeying vcpu_avail) is retained, but AFAICT it was not,
in this case vcpu==maxcpus==online cpus. This is good for us
because handling anything else would be fiddly.
This patch changes parsing of the virDomainDef maxvcpus and vcpus
entries to use the corresponding 'maxvcpus' and 'vcpus' settings
from xm and xl config. It also drops use of the old Xen 3.x
'vcpu_avail' setting.
The change also removes the maxvcpus limit of MAX_VIRT_VCPUS (since
maxvcpus is simply a count, not a bit mask), which is particularly
crucial on ARM where MAX_VIRT_CPUS == 1 (since all guests are
expected to support vcpu placement, and therefore only the boot
vcpu's info lives in the shared info page).
Existing tests adjusted accordingly, and new tests added for the
'maxvcpus' setting.

Always return LLONG_MAX even on 32 bit systems. The limitation
originates from our use of "unsigned long" in several APIs. The internal
data type is unsigned long long. Make the test suite deterministic by
removing the architecture difference.
Flaw was introduced in 645881139b where
I've added a test that uses too large numbers.
This updates the test program to make it consistent with recent changes
to the mock libraries, and also opens up the possibility of mocking more
than just /sys in the future.
Instead of fakesysfsdir, which is very generic, use fakesysfspcidir and
fakesysfscgroupdir. This makes it explicit what part of the fake sysfs
filesystem they're referring to, and also leaves open the possibility of
handling files in two unrelated parts of the fake sysfs filesystem.
No functional changes.
We might need to mock files living outside SYSFS_PREFIX later on,
so it's better to treat the temporary directory we are passed via
the environment as the root of the fake filesystem and create
SYSFS_PREFIX inside it.
The environment variable name will be changed to reflect the new use
we're making of it in a later commit.

Traditionally, we pass incoming migration URI on QEMU command line,
which has some drawbacks. Depending on the URI QEMU may initialize its
migration state immediately without giving us a chance to set any
additional migration parameters (this applies mainly for fd: URIs). For
some URIs the monitor may be completely blocked from the beginning until
migration is finished, which means we may be stuck in qmp_capabilities
command without being able to send any QMP commands.
QEMU solved this by introducing "defer" parameter for -incoming command
line option. This will tell QEMU to prepare for an incoming migration
while the actual incoming URI is sent using migrate-incoming QMP
command. Before calling this command we can normally talk to the
monitor and even set any migration parameters which will be honored by
the incoming migration.

tests: handle backspace-newline pairs in test input files
all the test argv files were line wrapped so that the args

The way the line wrapping was done turns out to be quite
undesirable, because it often leaves multiple parameters
on the same line. If we later need to add or remove
individual parameters, then it leaves us having to redo
line wrapping.
This commit changes the line wrapping so that every

When qemuDomainPinIOThread was added in commit id 'fb562614', a check
for the IOThread capability was not needed since a check for iothreadpids
covered the condition where the support for IOThreads was not present.
The iothreadpids array was only created if qemuProcessDetectIOThreadPIDs
was able to query the monitor for IOThreads. It would only do that if
the QEMU_CAPS_OBJECT_IOTHREAD capability was set.
However, when iothreadids were added in commit id '8d4614a5' and the
check for iothreadpids was replaced by a search through the iothreadids[]
array for the matching iothread_id that left open the possibility that
an iothreadids[] array was defined, but the entries essentially pointed
to elements with only the 'iothread_id' defined leaving the 'thread_id'
value of 0 and eventually the cpumap entry of NULL.
This was because, the original IOThreads commit id '72edaae7' only
checked if IOThreads were defined and if the emulator had the IOThreads
capability, then IOThread objects were added at startup. The "capability
failure" check was only done when a disk was assigned to an IOThread in
qemuCheckIOThreads. This was because the initial implementation had no way
to dynamically add IOThreads, but it was possible to dynamically add a
disk to the domain. So the decision was if the domain supported it, then
add the IOThread objects. Then if a disk with an IOThread defined was
added, it could check the capability and fail to add if not there. This
just meant the 'iothreads' value was essentially ignored.
Eventually commit id 'a27ed6e7' allowed for the dynamic addition and
deletion of IOThread objects. So it was no longer necessary to generate
IOThread objects to dynamically attach a disk to. However, the startup
and disk check code was not modified to reflect this.
This patch will move the capability failure check to when IOThread
objects are being added to the command line. Thus a domain that has
IOThreads defined will not be started if the emulator doesn't support
the capability. This means when qemuCheckIOThreads is called to add
a disk, it's no longer necessary to check the capability. Instead the
code can use the IOThreadFind call to indicate that the IOThread
doesn't exist.
Finally because it could be possible to have a domain running with the
iothreadids[] defined prior to this change if libvirtd is restarted each
having mostly empty elements, qemuProcessDetectIOThreadPIDs will check
if there are niothreadids when the QEMU_CAPS_OBJECT_IOTHREAD capability
check fails and remove the elements and array if it exists.
With these changes in place, it turns out the cputune-numatune test
was failing because the right bit wasn't set in the test. So used the
opportunity to fix that and create a test that would expect to fail
with some sort of iothreads defined and used, but not having the
correct capability.
It should redirect stdout to /dev/null first,
then redirect stderr to whatever stdout currently points at.

virtTestResult is suboptimal for a few reasons:
- It poorly duplicates virtTestRun pass/fail reporting logic
- It doesn't have virtTestRun's alloc testing support
- It only reports the test name _after_ the test has run.
- It doesn't follow the standard virtTestRun pattern that most other
tests use.
There's no users left, so drop it. If any other async tests like eventtest
spring up that don't cleanly fit the virtTestRun pattern, I suggest they
just open code the support for it around virtTestRun
These event tests aren't run synchronously, so there isn't an obvious
function to pass to virtTestRun. Instead, open code roughly what
virtTestResult did before: printing an error message if a test failed.
We are using memory-backing-file even when it's not needed, for example
if user requests hugepages for memory backing, but does not specify any
pagesize or memory node pinning. This causes migrations to fail when
migrating from older libvirt that did not do this. So similarly to
commit 7832fac847 which does it for
memory-backend-ram, this commit makes is more generic and
backend-agnostic, so the backend is not used if there is no specific
pagesize of hugepages requested, no nodeset the memory node should be
bound to, no memory access change required, and so on.

Introduce VIR_DOMAIN_VIRT_NONE to give domaintype the default value of zero.
This is specially helpful in constructing better error messages
when we don't want to look up the default emulator by virtType.
The test data in vircapstest.c is also modified to reflect this change.
My original implementation was based on a qemu version that still did
not have all the checks in place. Using sizes that would align to odd
megabyte increments will produce the following error:
qemu-kvm: -device pc-dimm,node=0,memdev=memdimm0,id=dimm0: backend memory size must be multiple of 0x200000
qemu-kvm: -device pc-dimm,node=0,memdev=memdimm0,id=dimm0: Device 'pc-dimm' could not be initialized
Introduce an alignment retrieval function for memory devices and use it
to align the devices separately and modify a test case to verify it.
We use the function to create a virDomainXMLOption object that is

For some machine types ppc64 machines now require that memory sizes are
aligned to 256MiB increments (due to the dynamically reconfigurable
memory). As now we treat existing configs reasonably in regards to
migration, we can round all the sizes unconditionally. The only drawback
will be that the memory size of a VM can potentially increase by
(256MiB - 1byte) * number_of_NUMA_nodes.

Tool such as libguestfs need the datacenter path to get access to disk
images. The ESX driver knows the correct datacenter path, but this
information cannot be accessed using libvirt API yet. Also, it cannot
be deduced from the connection URI in a robust way.
Expose the datacenter path in the domain XML as <vmware:datacenterpath>
node similar to the way the <qemu:commandline> node works. The new node
is ignored while parsing the domain XML. In contrast to <qemu:commandline>
it is output only.
Commit id 'f1f68ca33' added code to remove the directory paths for

Adds a new interface type using UDP sockets, this seems only applicable
to QEMU but have edited tree-wide to support the new interface type.
The interface type required the addition of a "localaddr" (local
address), this then maps into the following xml and qemu call.
<interface type='udp'>
<mac address='52:54:00:5c:67:56'/>
<source address='127.0.0.1' port='11112'>
<local address='127.0.0.1' port='22222'/>
</source>
<model type='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/>
</interface>
QEMU call:
-net socket,udp=127.0.0.1:11112,localaddr=127.0.0.1:22222
Notice the xml "local" entry becomes the "localaddr" for the qemu call.

Limitations of the POWER architecture mean that you can't run

basically the same on ppc64.
This means, of course, that hosts using different CPUs have to be

A test is considered successful if the obtained result matches
the expected result: if that's not the case, whether because a
test that was expected to succeed failed or because a test that
was supposed to fail succeeded, then something's not right and
we want the user to know about this.
On the other hand, if a failure that's unrelated to the bits
we're testing occurs, then the user should be notified even if
the test was expected to fail.
Use different values to tell these two situations apart.
Fix a test case that was wrongly expected to fail as well.
This patch modifies virSocketAddrGetRange() to function properly when
the containing network/prefix of the address range isn't known, for
example in the case of the NAT range of a virtual network (since it is
a range of addresses on the *host*, not within the network itself). We
then take advantage of this new functionality to validate the NAT
range of a virtual network.
Extra test cases are also added to verify that virSocketAddrGetRange()
works properly in both positive and negative cases when the network
pointer is NULL.

Commits 1e334a and 48e8b9 had earlier been pushed as fixes for that

fixing validation for the NAT range, I had fixed validation for the
DHCP range. sigh.
Since its introduction in 2011 (particularly in commit f4324e3292),
the option doesn't work. It just effectively disables all incoming
connections. That's because the client private data that contain the
'keepalive_supported' boolean, are initialized to zeroes so the bool is
false and the only other place where the bool is used is when checking
whether the client supports keepalive. Thus, according to the server,
no client supports keepalive.
Removing this instead of fixing it is better because a) apparently
nobody ever tried it since 2011 (4 years without one month) and b) we
cannot know whether the client supports keepalive until we get a ping or
pong keepalive packet. And that won't happen until after we dispatched
the ConnectOpen call.
Another two reasons would be c) the keepalive_required was tracked on
the server level, but keepalive_supported was in private data of the
client as well as the check that was made in the remote layer, thus
making all other instances of virNetServer miss this feature unless they
all implemented it for themselves and d) we can always add it back in
case there is a request and a use-case for it.

This controller can be connected only to a port on a
pcie-switch-upstream-port. It provides a single hotpluggable port that
will accept any PCI or PCIe device, as well as any device requiring a
pcie-*-port (the only current example of such a device is the
pcie-switch-upstream-port).
The downstream ports of an x3130-upstream switch can each have one of
these plugged into them (and that is the only place they can be
connected). Each xio3130-downstream provides a single PCIe port that
can have PCI or PCIe devices hotplugged into it. Apparently an entire
set of x3130-upstream + several xio3130-downstreams can be hotplugged
as a unit, but it's not clear to me yet how that would be done, since
qemu only allows attaching a single device at a time.
This device will be used to implement the
"pcie-switch-downstream-port" model of pci controller.
This controller can be connected only to a pcie-root-port or a
pcie-switch-downstream-port (which will be added in a later patch),
which is the reason for the new connect type
VIR_PCI_CONNECT_TYPE_PCIE_PORT. A pcie-switch-upstream-port provides
32 ports (slot=0 to slot=31) on the downstream side, which can only
have pci controllers of model "pcie-switch-downstream-port" plugged
into them, which is the reason for the other new connect type
VIR_PCI_CONNECT_TYPE_PCIE_SWITCH.
This is the upstream part of a PCIe switch. It connects to a PCIe port
(but not PCI) on the upstream side, and can have up to 31
xio3130-downstream controllers (but no other types of devices)
connected to its downstream side.
This device will be used to implement the "pcie-switch-upstream-port"
model of pci controller.
This is backed by the qemu device ioh3420.
chassis and port from the <target> subelement are used to store/set the
respective qemu device options for the ioh3420. Currently, chassis is
set to be the index of the controller, and port is set to
"(slot << 3) + function" (per suggestion from Alex Williamson).
This controller can be connected (at domain startup time only - not
hotpluggable) only to a port on the pcie root complex ("pcie-root" in
libvirt config), hence the new connect type
VIR_PCI_CONNECT_TYPE_PCIE_ROOT. It provides a hotpluggable port that
will accept any PCI or PCIe device.
New attributes must be added to the controller <target> subelement for
this - chassis and port are guest-visible option values that will be
set by libvirt with values derived from the controller's index and pci
address information.
This is a PCIE "root port". It connects only to a port of the
integrated pcie.0 bus of a Q35 machine (can't be hotplugged), and
provides a single PCIe port that can have PCI or PCIe devices
hotplugged into it.
This device will be used to implement the "pcie-root-port" model of
pci controller.
This uses the new subelement/attribute in two ways:
1) If a "pci-bridge" pci controller has no chassisNr attribute, it
will automatically be set to the controller's index as soon as the
controller's PCI address is known (during
qemuDomainAssignPCIAddresses()).
2) when creating the commandline for a pci-bridge device, chassisNr
will be used to set qemu's chassis_nr option (rather than the previous
practice of hard-coding it to the controller's index).
There are some configuration options to some types of pci controllers
that are currently automatically derived from other parts of the
controller's configuration. For example, in qemu a pci-bridge
controller has an option that is called "chassis_nr"; up until now
libvirt has always set chassis_nr to the index of the pci-bridge. So
this:
<controller type='pci' model='pci-bridge' index='2'/>
will always result in:
-device pci-bridge,chassis_nr=2,...
on the qemu commandline. In the future we may decide there is a better
way to derive that option, but even in that case we will need for
existing domains to retain the same chassis_nr they were using in the
past - that is something that is visible to the guest so it is part of
the guest ABI and changing it would lead to problems for migrating
guests (or just guests with very picky OSes).
The <target> subelement has been added as a place to put the new
"chassisNr" attribute that will be filled in by libvirt when it
auto-generates the chassisNr; it will be saved in the config, then
reused any time the domain is started:
<controller type='pci' model='pci-bridge' index='2'>
<model type='pci-bridge'/>
<target chassisNr='2'/>
</controller>
The one oddity of all this is that if the controller configuration
is changed (for example to change the index or the pci address
where the controller is plugged in), the items in <target> will
*not* be re-generated, which might lead to conflict. I can't
really see any way around this, but fortunately if there is a
material conflict qemu will let us know and we will pass that on
to the user.
This new subelement is used in PCI controllers: the toplevel
*attribute* "model" of a controller denotes what kind of PCI
controller is being described, e.g. a "dmi-to-pci-bridge",
"pci-bridge", or "pci-root". But in the future there will be different
implementations of some of those types of PCI controllers, which
behave similarly from libvirt's point of view (and so should have the
same model), but use a different device in qemu (and present
themselves as a different piece of hardware in the guest). In an ideal
world we (i.e. "I") would have thought of that back when the pci
controllers were added, and used some sort of type/class/model
notation (where class was used in the way we are now using model, and
model was used for the actual manufacturer's model number of a
particular family of PCI controller), but that opportunity is long
past, so as an alternative, this patch allows selecting a particular
implementation of a pci controller with the "name" attribute of the
<model> subelement, e.g.:
<controller type='pci' model='dmi-to-pci-bridge' index='1'>
<model name='i82801b11-bridge'/>
</controller>
In this case, "dmi-to-pci-bridge" is the kind of controller (one that
has a single PCIe port upstream, and 32 standard PCI ports downstream,
which are not hotpluggable), and the qemu device to be used to
implement this kind of controller is named "i82801b11-bridge".
Implementing the above now will allow us in the future to add a new
kind of dmi-to-pci-bridge that doesn't use qemu's i82801b11-bridge
device, but instead uses something else (which doesn't yet exist, but
qemu people have been discussing it), all without breaking existing
configs.
(note that for the existing "pci-bridge" type of PCI controller, both
the model attribute and <model> name are 'pci-bridge'. This is just a
coincidence, since it turns out that in this case the device name in
qemu really is a generic 'pci-bridge' rather than being the name of
some real-world chip)
If a pci address had a function number out of range, the error message
would be:
Insufficient specification for PCI address
which is logged by virDevicePCIAddressParseXML() after
virDevicePCIAddressIsValid returns a failure.
This patch enhances virDevicePCIAddressIsValid() to optionally report
the error itself (since it is the place that decides which part of the
address is "invalid"), and uses that feature when calling from
virDevicePCIAddressParseXML(), so that the error will be more useful,
e.g.:
Invalid PCI address function=0x8, must be <= 7
Previously, virDevicePCIAddressIsValid didn't check for the
theoretical limits of domain or bus, only for slot or function. While
adding log messages, we also correct that ommission. (The RNG for PCI
addresses already enforces this limit, which by the way means that we
can't add any negative tests for this - as far as I know our
domainschematest has no provisions for passing XML that is supposed to
fail).
Note that virDevicePCIAddressIsValid() can only check against the
absolute maximum attribute values for *any* possible PCI controller,
not for the actual maximums of the specific controller that this
device is attaching to; fortunately there is later more specific
validation for guest-side PCI addresses when building the set of
assigned PCI addresses. For host-side PCI addresses (e.g. for
<hostdev> and for network device pools), we rely on the error that
will be logged when it is found that the device doesn't actually
exist.

When cleaning up the data (taken from a running system) for inclusion
I went a little too far and deleted a bunch of links that should have

through a fallback code path.
A few other files are affected as well: again, the data is taken from
a running system, so even thought we would probably be okay if we
just added the links, aligning everything is definitely safer.
The scope name, even according to our docs is
"machine-$DRIVER\x2d$VMNAME.scope" virSystemdMakeScopeName would use the
resource partition name instead of "machine-" if it was specified thus
creating invalid scope paths.
This makes libvirt drop cgroups for a VM that uses custom resource
partition upon reconnecting since the detected scope name would not
match the expected name generated by virSystemdMakeScopeName.
The error is exposed by the following log entry:

The test case addition should help make sure that everything works.
So far the argument has not much meaning and was practically ignored.
This is not good since when doing memory hotplug, the size of desired
hugepage backing is passed in that argument. Taking closer look at the
tests I'm fixing reveals the bug. For instance, while the following is
in the test:
<memory model='dimm'>
<source>
<nodemask>1-3</nodemask>
<pagesize unit='KiB'>4096</pagesize>
</source>
<target>
<size unit='KiB'>524287</size>
<node>0</node>
</target>
<address type='dimm' slot='0' base='0x100000000'/>
</memory>
the generated commandline corresponding to this XML was:
-object memory-backend-ram,id=memdimm0,size=536870912,\
host-nodes=1-3,policy=bind
Have you noticed? Yes, memory-backend-ram! Nothing can be further away
from the right answer. The hugepage backing is requested in the XML
and we happily ignore it. This is just not right. It's
memory-backend-file which should have been used:
-object memory-backend-file,id=memdimm0,prealloc=yes,\
mem-path=/dev/hugepages4M/libvirt/qemu,size=536870912,\
host-nodes=1-3,policy=bind
The problem is, that @pagesize passed to qemuBuildMemoryBackendStr
(where this part of commandline is built) was ignored. The hugepage to
back memory was searched only and only by NUMA nodes pinning. This
works only for regular guest NUMA nodes.
Then, I'm changing the hugepages size in the test XMLs too. This is
simply because in the test suite we create dummy mount points just for
2M and 1G hugepages. And in the test 4M was requested. I'm sticking to
2M, but 1G should just work too.

There is, however, one 'corner case'. Users may just tell 'use

Commit ceb496e5 fails on RHEL 6, with yajl 1.0.7, because that
version of yajl returns yajl_status_insufficient_data when the
parser is waiting for the rest of a token (this enum value was
dropped in yajl 2, so we have to wrap it). It also exposes a
problem where older yajl silently ignores trailing garbage after
a successful parse, so this patch works around that by changing
the testsuite. Another more invasive patch can add tighter
semantics to json parsing, but this is sufficient for a minimal
clean backport.
While touching this, fix up our error message cleanup. Yajl
documents that error messages produced by yajl_get_error()
MUST be cleaned with yajl_free_error(); this is certainly
true if we were to pass non-NULL allocator callbacks during
yajl_alloc(), but probably harmless in our usage of passing
NULL. But better safe than sorry.

Defining a domain with a SCSI disk attached via a hostdev
tag and a source address unit value longer than two digits
causes an error when editing the domain with virsh edit,
even if no changes are made to the domain definition.
The error suggests invalid XML, somewhere:
# virsh edit lmb_guest
error: XML document failed to validate against schema:
Unable to validate doc against /usr/local/share/libvirt/schemas/domain.rng
Extra element devices in interleave
Element domain failed to validate content

Relax-NG validity error : Extra element devices in interleave
lmb_guest.xml:17: element devices: Relax-NG validity error :
Element domain failed to validate content
lmb_guest.xml fails to validate
The hostdev tag requires a source address to be specified,
which includes bus, target, and unit address attributes.
According to the SCSI Architecture Model spec (section
4.9 of SAM-2), a LUN address is 64 bits and thus could be
up to 20 decimal digits long. Unfortunately, the XML
schema limits this string to just two digits. Similarly,
the target field can be up to 32 bits in length, which
would be 10 decimal digits.

Since the reference unit and target fields are used in
several places in the XML schema, create a separate one
specific for SCSI Logical Units that will permit the
greater length. This permits both the validation utility
and the virsh edit command to succeed when a hostdev
tag is included.
