Per-domain directories were introduced in order to be able to
completely separate security labels for each domain (commit
f1f68ca334). However when the domain
name is long (let's say a ridiculous 110 characters), we cannot
connect to the monitor socket because on length of UNIX socket address
is limited. In order to get around this, let's shorten it in similar
fashion and in order to avoid conflicts, throw in an ID there as well.
Also save that into the status XML and load the old status XMLs
properly (to clean up after older domains). That way we can change it
in the future.
The shortening can be seen in qemuxml2argv tests, for example in the
hugepages-pages2 case.

Test all kinds of scenarios, including guests asking for GIC but
failing to specify a version, guests specifying an invalid version
and guests trying to use GIC with non-virt or even non-ARM machines.
Unify the naming to prepare for new test cases that will be added
later on.
Convert a couple of output XML files for the qemuxml2xml test to
symlinks while at it, since they were identical to the corresponding
input XML files anyways.
Moreover, since we're only interested in testing GIC support here,
simplify XML files by getting rid of the unrelevant bits.
We use the PreFormat callback for this. Many test cases need to be extended
to pass in proper qemuCaps flags so AssignAddresses doesn't throw errors.
One test case (pcie-root-port-too-many) is dropped, since it was meant
only for checking an error condition in qemuxml2argv, and one we add in
AssignAddresses it errors here too.
Long term I think AssignAddresses should be handled in qemu's PostParse
callback, but that's not entirely straightforward. Handling it here
means we can get the test suite churn over with.
When we unconditionally enable QEMU_CAPS_DEVICE, these tests need
some massaging, so do it ahead of time to not mix it in with the
big test refresh.
- minimal-s390 is not a real world working config, so drop it
- disk-usb was testing for an old code path that will be removed.
instead use it to test lack of USB disk support, and rename it
to disk-usb-nosupport. Switch xml2xml to use disk-usb-device for
input.
- cputune-numatune was needlessly using q35, switch it to an older
machine type
Most qemuxml2xml tests expect that the input XML is unchanged after
parsing. This is unlike 99% of new qemu configs in the wild, which after
initial parsing end up with stable PCI device addresses. The xml2xml bit
doesn't currently hit that code path though, so most XML testing indeed
does not change.
Future patches will add that PCI address bits, which means most test cases
will have different output. So let's do away with the hardcoded same vs
different test split, and always track a separate output file. Tests can
still have same input and output, it just necessitates 2 separate XML files.
The virDomainObjFormat and virDomainSaveStatus methods
both call into virDomainDefFormat, so should be providing
a non-NULL virCapsPtr instance.

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.
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.
This patch enable regeneration of expected output file for
virTestDifferenceFull. It also introduces new
virTestDifferenceFullNoRegenerate function for special cases, where we
don't want to regenerate output.

Introduced by 8fedbbdb, if we parse an unordered NUMA cell, will
get a segfault. This is because of a check for overlapping @cpus
sets we have there. However, since the array to hold guest NUMA
cells is allocated upfront and therefore it contains all zeros,
an out of order cell will break our assumption that cell IDs have
increasing character. At this point we try to access yet NULL
bitmap and therefore segfault.

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.

The numad hint stored in priv->autoNodeset is information that gets lost
during daemon restart. And because we would like to use that
information in the future, we also need to save it in the status XML.
For the sake of tests, we need to initialize nnumaCell_max to some
value, so that the restoration doesn't fail in our test suite. There is
no need to fill in the actual numa cell data since the recalculating
function virCapabilitiesGetCpusForNodemask() will not fail, it will just
skip filling the data in the bitmap which we don't use in tests anyway.

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).
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 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.

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
The virt-xml-validate tool fails with a similar error:
# virt-xml-validate lmb_guest.xml
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.
