      qemu: Fix incorrect jump labels in error paths · eca76884
      由 Marc Hartmayer 提交于 
      Fix incorrect jump labels in error paths as the stop jump is only
needed if the driver has already changed the state. For example
'virAtomicIntInc(&driver->nactive)' will be 'reverted' in the
qemuProcessStop call.

      qemu_cgroup: Only try to allow devices if devices CGroup's available · 3cddd63a
      由 Michal Privoznik 提交于 
      When a domain needs an access to some device (be it a disk, RNG,
chardev, whatever), we have to allow it in the devices CGroup (if
it is available), because by default we disallow all the devices.
But some of the functions that are responsible for setting up
devices CGroup are lacking check whether there is any CGroup
available. Thus users might be unable to hotplug some devices:

  virsh # attach-device fedora rng.xml
  error: Failed to attach device from rng.xml
  error: internal error: Controller 'devices' is not mounted

      Add ATTRIBUTE_FALLTHROUGH for switch cases without break · 5d84f596
      由 Daniel P. Berrange 提交于 
      In GCC 7 there is a new warning triggered when a switch
case has a conditional statement (eg if ... else...) and
some of the code paths fallthrough to the next switch
statement. e.g.

conf/domain_conf.c: In function 'virDomainChrEquals':
conf/domain_conf.c:14926:12: error: this statement may fall through [-Werror=implicit-fallthrough=]
         if (src->targetTypeAttr != tgt->targetTypeAttr)
            ^
conf/domain_conf.c:14928:5: note: here
     case VIR_DOMAIN_CHR_DEVICE_TYPE_CONSOLE:
     ^~~~
conf/domain_conf.c: In function 'virDomainChrDefFormat':
conf/domain_conf.c:22143:12: error: this statement may fall through [-Werror=implicit-fallthrough=]
         if (def->targetTypeAttr) {
            ^
conf/domain_conf.c:22151:5: note: here
     default:
     ^~~~~~~

GCC introduced a __attribute__((fallthrough)) to let you
indicate that this is intentionale behaviour rather than
a bug.

      Current code for example can call unsubscribe if connection
succeeds but subscribing fails. This will probabaly lead
only to spurious error messages without any actual inconsistencies

      virsh: Alter formatting a bit for output of domstats fields · ff029e44
      由 John Ferlan 提交于 
      Alter the formatting of each line to not give the appearance of
one long run-on sentence and to be consistent between the various
elements of collected/displayed data. The formatting should fit
within the 80 character display. This removes the need for commas
at the end of each line.

      qemu: Allow multiple bridges when pci-bridges is not available · 011d5465
      由 Andrea Bolognani 提交于 
      qemuDomainAssignPCIAddresses() hardcoded the assumption
that the only way to support devices on a non-zero bus is
to add one or more pci-bridges; however, since we now
support a large selection of PCI controllers that can be
used instead, the assumption is no longer true.

Moreover, this check was always redundant, because the
only sensible time to check for the availability of
pci-bridge is when building the QEMU command line, and
such a check is of course already in place.

In fact, there were *two* such checks, but since one of
the two was relying on the incorrect assumption explained
above, and it was redundant anyway, it has been dropped.

      tests: Reduce usage of legacy PCI controllers on PCIe machines · d4393c42
      由 Andrea Bolognani 提交于 
      Up until a while ago, libvirt would automatically add a legacy
PCI controllers combo (dmi-to-pci-bridge + pci-bridge) to any
PCIe machine type (x86_64/q35 and aarch64/virt).

As a result, a number of input and output files in the test
suite ended up containing the legacy PCI controllers, even
though they are not needed or in any way relevant to the
feature being tested.

Get rid of most of the occurrences. Most of the time, this
just means removing the controllers from the input file and
regenerating the output files; in a few instances, some
minor tweaking is performed on the input file, most notably
removing the memory balloon: as memory balloon support was
not the scope of the test being changed, there is no loss
of test coverage from doing so.

Several occurrences of the legacy PCI controllers remain in
the test suite, both because removing their usage would have
required even more tweaking, and because we still want to
have coverage of this perfectly valid combination.

      When switching over the values in the virDomainControllerModelPCI
enumeration, make sure the proper cast is in place so that the
compiler can warn us when the coverage is not exaustive.

For the same reason, remove the 'default' case from one of the
existing switch statements.

      When switching over the values in the virDomainControllerModelPCI

For the same reason, fold some unstructured checks (performed by
comparing directly against some values in the enumeration) inside
an existing switch statement.
