Trying to print pages of a size larger than the UINT_MAX of the

system error even though this is a legitimate request.
The vshCommandOptScaledInt() used for parsing the pagesize is
given UINT_MAX as the upper limit. The parsed value is then
divided by 1024 and fed to virNodeGetFreePages() which expects an
unsigned int. We can't change the public API but the upper limit

While glibc provides qsort(), which usually is just a mergesort,
until sorting arrays so huge that temporary array used by
mergesort would not fit into physical memory (which in our case
is never), we are not guaranteed it'll use mergesort. The
advantage of mergesort is clear - it's stable. IOW, if we have an
array of values parsed from XML, qsort() it and produce some
output based on those values, we can then compare the output with
some expected output, line by line.
But with newer glibc this is all history. After [1], qsort() is
no longer mergesort but introsort instead, which is not stable.
This is suboptimal, because in some cases we want to preserve
order of equal items. For instance, in ebiptablesApplyNewRules(),
nwfilter rules are sorted by their priority. But if two rules
have the same priority, we want to keep them in the order they
appear in the XML. Since it's hard/needless work to identify
places where stable or unstable sorting is needed, let's just
play it safe and use stable sorting everywhere.
Fortunately, glib provides g_qsort_with_data() which indeed
implement mergesort and it's a drop in replacement for qsort(),
almost. It accepts fifth argument (pointer to opaque data), that
is passed to comparator function, which then accepts three
arguments.
We have to keep one occurance of qsort() though - in NSS module
which deliberately does not link with glib.

huge if-else block for nearly every architecture, except ARM.
Now, IOMMU is called SMMU in ARM world, and while there's
certainly a definitive way of detecting SMMU support (e.g. via
dumping some registers in asm), we can work around this - just
like we do for Intel and AMD - and check for an ACPI table
presence.

In virsh, we have this convenient domif-setlink command, which is
just a wrapper over virDomainUpdateDeviceFlags() and which allows
setting link state of given guest NIC. It does so by fetching
corresponding <interface/> XML snippet and either putting <link
state=''/> into it, OR if the element already exists setting the
attribute to desired value. The XML is then fed into the update
API.
There's, however, a small bug in detecting the pre-existence of
the element and its attribute. The code looks at "link"
attribute, while in fact, the attribute is called "state".

The script had an incorrect interpreter line until commit
f6a19d7264, so the flake8 check would not realize it needed
to pick it up and these issues, some of which were present it
the very first version that was committed, were not being
reported.

Scripts from the following list were installed with group write
bit set: virt-xml-validate, virt-pki-validate,
virt-sanlock-cleanup, libvirt-guests.sh. This is very unusual and
in contrast with the way other scripts/binaries are installed.

When running virsh snapshot-* command, such as snapshot-create-as /
snapshot-delete, it prints a result message.
On the other hand virsh snapshot-revert command doesn't print a result
message.
So, This patch fixes to add message when running virsh snapshot-revert
command.
# virsh snapshot-create-as vm1 test1

The return value of virXMLPropString was assigned into 'tmp' multiple
times and to prevent static analyzers moaning about a potential leak a
short-circuited if logic or was used.
Replace the code by having a helper variable for each possibility and
also replace the for-loop to iterate elements.

The XPath lookup guarantees that the top level element is always 'disk'
so there's no need to check that it actually is. We can also remove the
two unnecessary temporary variables.
