The libxl library allows a libxl_domain_config object to be serialized
from/to a JSON string. Use this to allow testing of the XML to
libxl_domain_config conversion process. Test XML is converted to
libxl_domain_config, which is then serialized to json. A json template
corresponding to the test XML is converted to a libxl_domain_config
object using libxl_domain_config_from_json(), and then serialized
back to json using libxl_domain_config_to_json(). The two json
docs are then compared.
Using libxl to convert the json template to a libxl_domain_config
object and then back to json provides a simple way to account for
any changes or additions to the json representation across Xen
releases.

Certain XML features that aren't in the <cpu> block map to -cpu
flags on the qemu cli. If one of these is specified but the user
didn't explicitly pass an XML <cpu> model, we need to format a
default model on the command line.
The current code handles this by sprinkling this default cpu handling
among all the different flag string formatting. Instead, switch it
to do this just once.
This alters some test output slightly: the previous code would
write the default -cpu in some cases when no flags were actually
added, so the output was redundant.

Disk serial schema has extra '.+' allowed characters in comparison
with check in code. Looks like there is no reason for that as qemu
allows any character AFAIK for serial. This discrepancy is originated

Alter the disk-serial test to add a disk with all the possible

Prior to qemu 2.5 the node names would not be generated, thus would be

Add a path for UEFI VMs for AArch32 VMs, based on the path Debian is using.
libvirt is the de facto canonical location for defining where distros
should place these firmware images, so let's define this path here to try
and minimize distro fragmentation.
This patch addresses the same aspects on PPC the bug 1103314 addressed
on x86.
PCI expander bus creates multiple primary PCI busses, where each of these
busses can be assigned a specific NUMA affinity, which, on x86 is
advertised through ACPI on a per-bus basis.
For SPAPR, a PHB's NUMA affinities are assigned on a per-PHB basis, and
there is no mechanism for advertising NUMA affinities to a guest on a
per-bus basis. So, even if qemu-ppc manages to get some sort of multi-bus
topology working using PXB, there is no way to expose the affinities
of these busses to the guest. It can only be exposed on a per-PHB/per-domain
basis.
So patch enables NUMA node tag in pci-root controller on PPC.
The way to set the NUMA node is through the numa_node option of
spapr-pci-host-bridge device. However for the implicit PHB, the only way
to set the numa_node is from the -global option. The -global option applies
to all the PHBs unless explicitly specified with the option on the
respective PHB of CLI. The default PHB has the emulated devices only, so
the patch prevents setting the NUMA node for the default PHB.

Currently the scan of the /proc/mounts file used to find cgroup mount
points doesn't take into account that mount points may hidden by other
mount points. For, example in certain Kubernetes environments the
/proc/mounts contains the following lines:
cgroup /sys/fs/cgroup/net_prio,net_cls cgroup ...
tmpfs /sys/fs/cgroup tmpfs ...
cgroup /sys/fs/cgroup/net_cls,net_prio cgroup ...
In this particular environment the first mount point is hidden by the
second one. The correct mount point is the third one, but libvirt will
never process it because it only checks the first mount point for each
controller (net_cls in this case). So libvirt will try to use the first
mount point, which doesn't actually exist, and the complete detection
process will fail.
To avoid that issue this patch changes the virCgroupDetectMountsFromFile
function so that when there are duplicates it takes the information from
the last line in /proc/mounts. This requires removing the previous
explicit condition to skip duplicates, and adding code to free the
memory used by the processing of duplicated lines.

https://bugs.debian.org/764918 are in a different directory for
some reason. Let the virtual machine read both.

My fix 671d18594f was incomplete. If domain doesn't have
hugepages enabled, because of missing condition we would still be
putting hugepages path onto qemu cmd line. Clean up the
conditions so that it's more visible next time.

Consider the following XML:
<memoryBacking>
<hugepages>
<page size='2048' unit='KiB' nodeset='1'/>
</hugepages>
<source type='file'/>
<access mode='shared'/>
</memoryBacking>
<numa>
<cell id='0' cpus='0-3' memory='512000' unit='KiB'/>
<cell id='1' cpus='4-7' memory='512000' unit='KiB'/>
</numa>
The following cmd line is generated:
-object
memory-backend-file,id=ram-node0,mem-path=/var/lib/libvirt/qemu/ram,
share=yes,size=524288000 -numa node,nodeid=0,cpus=0-3,memdev=ram-node0
-object
memory-backend-file,id=ram-node1,mem-path=/var/lib/libvirt/qemu/ram,
share=yes,size=524288000 -numa node,nodeid=1,cpus=4-7,memdev=ram-node1
This is obviously wrong as for node 1 hugepages should have been
used. The hugepages configuration is more specific than <source
type='file'/>.

We have couple of hugepage enabled domains for qemuxml2argvtest.
Unfortunately, often when adding a test case there I forget to
add it to xml2xml test too.

Commit 824272cb28 attempted to fix escaping of characters in unix
socket path but it was wrong. We need to escape only ',', there is
no escape character for '='.

Currently, we are querying for vhostuser interface name in post
parse callback. At that time interface might not yet exist.
However, it has to exist when starting domain. Therefore it makes
more sense to query its name at that point. This partially
reverts 57b5e27.

This will be used later when a save cookie will become part of the
snapshot XML using new driver specific parser/formatter functions.

Make the decision based on the usage of childBuf buffer.
This fixes the oddity in the test case introduced by commit c1c4d0d
where we would format an empty pair tag.
In 4f0aeed I've expanded the list of arguments for
virDomainDefCheckABIStability() but I forgot to fix
bhyveargv2xmltest.

The memset() was resetting only 30 bytes in the array (size of the
array), but it is array of pointers. Since it is a static array,
let's just reset it by its size.
Found by gcc-7.1:
testutils.c: In function 'virTestRun':
testutils.c:243:13: error: 'memset' used with length equal to number
of elements without multiplication by element size [-Werror=memset-elt-size]
memset(testAllocStack, 0, ARRAY_CARDINALITY(testAllocStack));

While checking for ABI stability, drivers might pose additional
checks that are not valid for general case. For instance, qemu
driver might check some memory backing attributes because of how
qemu works. But those attributes may work well in other drivers.
