Raw local files do not pass through the backing store detector and thus
the code did not allocate the required backing store terminator for
them. Previously the terminating element would be formatted into the XML
since the default values used for the metadata allowed that. This is a
regression since a693fdba01 which was not detected in the review.
This patch also reverts all the changes in the test files.
In status XML, we do not store the QEMU version information, we only
format all the capabilities. We dropped QEMU_CAPS_PCI_MULTIBUS
in commit 5b783379 which was released in libvirt 3.2.0.
Therefore the only way of telling if the already running domain
at the time of daemon restart has been started with a QEMU that does
use 'pci.0' or not on PPC is to look at the pci-root controller's
alias. This is not an option if the domain has a user-specified alias
for the pci-root.
Instead of reintroducing the capability, assume 'pci.0' when we have
no version information. That way the only left broken use case would
be the combination of user aliases and very old QEMU.
Partially reverts commit 3a37af1e4.

We do not fill out qemuCaps->arch when parsing status XML.
Use def->os.arch like we do for PPC.
This fixes hotplug after daemon restart for domains that use

This patch modifies some not yet used test data so that the adding a test using
this data is a clean patch and not an addition of huge file with some
adjustments in small files that will be hidden in the middle of that commit.
These changes include:
- Add system dir in vircaps2xmldata/linux-caches
Back when data for systems with resctrl support were added they had the
/sys/fs/system directory put into a system/ subdir of the test and
/sys/fs/resctrl in a resctrl/ subdir of that test. However, if we also want a
negative test for the resctrl (requesting allocation on a system that does not
support resctrl), we need one a test case with any sensible (with cache info)
system/ subdir and no resctrl/ one. Easiest way is to add a
system -> . symlink into existing test case.
- Change default group schemata for linux-resctrl and linux-resctrl-cdp
That way we can fit some allocation in.
- Remove one cache from resctrl-skx's schemata and make some room for
allocations
That system already has only one cache, so that file was wrong anyway. We
have a version with 2 caches already (linux-resctrl-skx-twocaches), so this
will also add variety to future tests.
- Add some empty allocation for resctrl-skx
Just to have slightly more coverage and variety. We can be sure nothing bad
happens if such allocation exists in case we have that in the tests.

Libvirt historically stores storage source path including the volume as
one string in the XML, but that is not really flexible enough when
dealing with the fields in the code. Previously we'd store the slash
separating the two as part of the image name. This was fine for gluster
but it's not necessary and does not scale well when converting other
protocols.
Don't store the slash as part of the path. The resulting change from
absolute to relative path within the gluster driver should be okay,
as the root directory is the default when accessing gluster.
Original implementation used 'SocketAddress' equivalent from qemu for
the disk server field, while qemu documentation specifies
'InetSocketAddress'. The backing store parser uses the correct parsing
function but the formatter used the incorrect one (and also with the
legacy mode enabled which was wrong).
Right-aligning backslashes when defining macros or using complex
commands in Makefiles looks cute, but as soon as any changes is
required to the code you end up with either distractingly broken
alignment or unnecessarily big diffs where most of the changes
are just pushing all backslashes a few characters to one side.

Since we've allowed the <auth> to be a child of <disk>, we'll need
to keep track of how it was read so that when writing out we'll know
whether to format as child of <disk> or <source>. For the argv2xml

Express a properly terminated backing chain by putting a
virStorageSource of type VIR_STORAGE_TYPE_NONE in the chain. The newly
used helpers simplify this greatly.
The change fixes a bug as formatting an incomplete backing chain and
parsing it back would end up in expressing a terminated chain since
src->backingStoreRaw was not populated. By relying on the terminator
object this can be now processed appropriately.
Add helpers that will simplify checking if a backing file is valid or
whether it has backing store. The helper virStorageSourceIsBacking
returns true if the given virStorageSource is a valid backing store
member. virStorageSourceHasBacking returns true if the virStorageSource
has a backing store child.
Adding these functions creates a central points for further refactors.

The default_tls_x509_verify (and related) parameters in qemu.conf
control whether the QEMU TLS servers request & verify certificates
from clients. This works as a simple access control system for
servers by requiring the CA to issue certs to permitted clients.
This use of client certificates is disabled by default, since it
requires extra work to issue client certificates.
Unfortunately the code was using this configuration parameter when
setting up both TLS clients and servers in QEMU. The result was that
TLS clients for character devices and disk devices had verification
turned off, meaning they would ignore errors while validating the
server certificate.
This allows for trivial MITM attacks between client and server,
as any certificate returned by the attacker will be accepted by
the client.

In the past we updated host-model CPUs with host CPU data by adding a
model and features, but keeping the host-model mode. And since the CPU
model is not normally formatted for host-model CPU defs, we had to pass
the updateCPU flag to the formatting code to be able to properly output
updated host-model CPUs. Libvirt doesn't do this anymore, host-model
CPUs are turned into custom mode CPUs once updated with host CPU data
and thus there's no reason for keeping the hacks inside CPU XML
formatters.

gnutls-3.3.0 and newer leaves 2 FDs open in order to be backwards
compatible when it comes to chrooted binaries [1]. Linking
commandhelper with gnutls then leaves these two FDs open and
commandtest fails thanks to that. This patch does not link
commandhelper with libvirt.la, but rather only the utilities making
the test pass.
Based on suggestion from Daniel [2].

gnutls, libvirt_util.la did not link to it. With the
introduction of the util/vircrypto.c file that assumption
is no longer valid. We must not link to libvirt_util.la
at all - only gnulib and libc can (hopefully) be relied

Add a couple of tests to "validate" checks in domain_conf that either

Alter the example to remove the <auth> from:

from the storage source pool will supercede whatever is in the <disk>
definition during virStorageTranslateDiskSourcePool processing. In fact,
if the pool doesn't have/need authentication, then the authdef would
be removed anyway as the storage pool would be handling things.
The "proof" for this is in the adjustment to the test to add an

If the "/#" is missing from the provided iSCSI path, then we need
to provide the default LUN of /0; otherwise, QEMU will fail to parse
the URL causing a failure to either create the guest or hotplug
attach the storage.
During post parse, for any iSCSI disk or hostdev, scan the source
path looking for the presence of '/', if found, then we can assume
the LUN is provided. If not found, alter the input XML to add the
"/0". This will cause the generated XML to have the generated
value when the domain config is saved after post parse.

Currently while parsing domain XML we clear the UNIX path if it matches
one of the auto-generated paths by libvirt. After that when the guest
is started new path is generated but the mode is also changed to "bind".
In the real-world use-case the mode should not change, it only happens
if a user provides a mode='connect' and path that matches one of the
auto-generated path or not provides a path at all.
Before *reconnect* feature was introduced there was no issue, but with
the new feature we need to make sure that it's used only with "connect"
mode, therefore we need to move the mode change into parsing in order
to have a proper error reported by validation code.

Our backing probing code handles directory file types properly in
virStorageFileGetMetadataRecurse(), by that I mean it leaves them
alone. However its caller, the virStorageFileGetMetadata() resets the
type to raw before probing, without even checking the type. We need
to special-case TYPE_DIR in order to achieve desired results.
Also, in order to properly test this, we need to stop resetting format
of volumes in tests for TYPE_DIR (probably the reason why we didn't
catch that and why the test data didn't need to be modified).

<source mode='connect'/>
<source mode='bind' host='localhost'/>
<source service='4567'/>
<target type='virtio' name='test'/>

The parsed formatted XML is:
...
<channel type='tcp'>
<source mode='connect' host='localhost' service='4567'/>
<target type='virtio' name='test'/>
</channel>
...
That behavior is super wrong and should not be allowed. If you notice
the current parse takes the first found attribute and uses that value,
so for example from the "<source mode='bind' host='localhost'/>" only
the "host" attribute is used. It works the same way for all possible
attributes that we are able to parse for source element.

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

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

The test case change is necessary as our test file checker does not play

behind a storage volume and 'backing' corresponds to the lower level of
backing chain. Since all have node names this data can be really easily
