Shorten the rewrap subroutine by splitting out the code
dealing with a single line.

Also remove $file from the warning.

We already have a syntax-check to prohibit direct use of these
allocation functions.

There is a definiton of VIR_FROM_THIS just two lines above.

The rest is defined in vbox_common.h.

Introduced by commit d5756794, unused at the time.

In the case of chassisNr (used to set chassis_nr of a pci-bridge
controller), 0 is reserved for / used by the pci[e]-root bus. In the
base of busNr, a value of 0 would mean that the root bus had no places
available to plug in new buses, including the pxb itself (the
documentation I wrote for pxb even noted the limit of busNr as 1.254).

NB: oddly, the "chassis" attribute, which is used for pcie-root-port
and pcie-switch-downstream-port *can* be set to 0, since it's the
combination of {chassis, slot} that needs to be unique, not chassis by
itself (and slot 0 of pcie-root is reserved, while pcie-*-port can use
*only* slot 0).

Thanks to our smart option parser which automatically assigns positional
parameters the following (previously working) command fails:

    virsh migrate test qemu+ssh://1.2.3.4/system tcp://1.2.3.4/
    error: invalid argument: Unsupported compression method
    'tcp://1.2.3.4/'

We need to make sure new options are added at the end of the list rather
than where they logically belong.

This test only checks if mocking of virRandomBytes works correctly.

Drop it to avoid infinite recursion by testing the test suite.

This tests checks that the first word after SYNOPSIS
in virsh help ${command} output is ${command}.

This was only good to check that the command option structures
are valid, which is now served by 'virsh self-test'.

A new hidden command for virsh that will iterate over
all command groups and commands and print help for every single one.

This involves running vshCmddefOptParse so we can get an error if
one of the command's option structure is invalid.

This function generates some big random numbers.

Cache the result and supply it to any subsequent generate2 calls.

Since e8ac4a79 this test wastes some CPU cycles by blindly trying to
run almost every virsh command, blindly throwing away the output
and the return value and returning success if 'virsh help' successfully
returned at least one command.

Drop it completely.

Since introduction of the DAC security driver we've documented that
seclabels with a leading + can be used with numerical uid. This would
not work though with the rest of libvirt if the uid was not actually
used in the system as we'd fail when trying to get a list of
supplementary groups for the given uid. Since a uid without entry in
/etc/passwd (or other user database) will not have any supplementary
groups we can treat the failure to obtain them as such.

This patch modifies virGetGroupList to not report the error for missing
users and makes it return an empty list or just the group specified in
@gid.

All callers will grant less permissions to a user in case of failure of
this function and thus this change is safe.

In some cases it will be necessary to ignore errors reported from this
function. This allows suppressing them to avoid spamming logs.

Whine about 'allowed_users' having wrong format rather than 'shell'

The list certainly isn't zero terminated and it would disallow usage of
group 'root'. Pass in the array size and match against it.

Use 'cleanup' since it's also used on success.

Crash dump in a old kvmdump format is being obsolete and cannot be loaded and
processed by crash utility since its version 6.1.0. A --memory-only option is
required in order to produce valid ELF file which can be later processed by the
crash utility. A new note is added to the dump command description.

Use virBitmapParseUnlimited to parse the env variable.

For parsing a bitmap of an unknown size.

Most the callers pass 0 in one form or another, including
vircapstest which used VIR_ARCH_NONE.

This will be used for the caller that needs to specify a separator.
Currently identical to virBitmapParse.

Also change one test case to use the new function.

This is only used by one caller.

The '-usb' option doesn't have any effect for aarch64 mach-virt
guests, so the fact that it's currently enabled by default is not
really causing any issue.

However, that might change in the future (although unlikely), and
having it as part of the QEMU command line can cause confusion to
someone looking through the process list.

Avoid it completely, like it's already happening for q35.

Similar to 'event' and 'net-event', this prints info about incoming
storage pool events.

Commit 2a58ed0b added support for creating guests with USB
hostdevs. Commit fc21d106 later added support for hotplut of
USB hostdevs. Advertise support for USB hostdevs in the
domcapabilities.

In addition add the appropriate caps for USB support on
domaincapstest when libvirt is built on a Xen with
LIBXL_HAVE_PVUSB. Otherwise domaincapstest would fail i.e.
testing the wrong domain capabilities.

Commit 409de00e changed the logic to only match PCI devices
while moving this before Remove*HostDevice calls.

https://bugzilla.redhat.com/show_bug.cgi?id=1342874

There has been some progress lately in enabling virtio-pci on
aarch64 guests; however, guest OS support is still spotty at best,
so most guests are going to be using virtio-mmio instead.

Currently, mach-virt guests are closely modeled after q35 guests,
and that includes always adding a dmi-to-pci-bridge that's just
impossible to get rid of. While that's acceptable (if suboptimal)
for q35, where you will always need some kind of PCI device anyway,
mach-virt guests should be allowed to avoid it.

This is fairly simple. We lookup the device in the array of
devices and remove it. No magic.

This is really simple, we just need to append the device into the
domain def and that's it.

This is going to be important later when we received
DEVICE_DELETED event on the qemu monitor. If we do,
virDomainDefFindDevice() is called to find the device for given
device alias in the virDomainDef tree. When we enable removal for
redirdevs we need to include them in the lookup process too.

Basically, there are just two functions introduced here:
virDomainRedirdevDefFind which looks up given redirdev in domain
definition, and virDomainRedirdevDefRemove which removes the
device at given index in the array of devices.

There's currently just one limitation: redirdevs that want to go
on USB bus require a USB controller, surprisingly.
At the same time, since I'm using virDomainDefHasUSB() in this
new validator function, it has to be moved a few lines up and
also its header needed to be changed a bit: it is now taking a
const pointer to domain def since it's not changing anything in
there.
