      conf: force 8 byte alignment for virObjectEvent · 37ae0426
      由 Daniel P. Berrangé 提交于 
      We need to be able to cast from virObjectEventPtr to one of
its many subclasses. Some of these subclasses have 8 byte
alignment on 32-bit platforms, but virObjectEventPtr only
has 4 byte alignment.

Previously the virObject base class had 8 byte alignment
but this dropped to 4 byte when converted to inherit from
GObject. This introduces cast alignment warnings on 32-bit:

../../src/conf/domain_event.c: In function 'virDomainEventDispatchDefaultFunc':
../../src/conf/domain_event.c:1656:30: error: cast increases required alignment of target type [-Werror=cast-align]
 1656 |             rtcChangeEvent = (virDomainEventRTCChangePtr)event;
      |                              ^
../../src/conf/domain_event.c:1785:34: error: cast increases required alignment of target type [-Werror=cast-align]
 1785 |             balloonChangeEvent = (virDomainEventBalloonChangePtr)event;
      |                                  ^
../../src/conf/domain_event.c:1896:35: error: cast increases required alignment of target type [-Werror=cast-align]
 1896 |             blockThresholdEvent = (virDomainEventBlockThresholdPtr)event;
      |                                   ^
../../src/conf/domain_event.c: In function 'virDomainQemuMonitorEventDispatchFunc':
../../src/conf/domain_event.c:1974:24: error: cast increases required alignment of target type [-Werror=cast-align]
 1974 |     qemuMonitorEvent = (virDomainQemuMonitorEventPtr)event;
      |                        ^
../../src/conf/domain_event.c: In function 'virDomainQemuMonitorEventFilter':
../../src/conf/domain_event.c:2179:20: error: cast increases required alignment of target type [-Werror=cast-align]
 2179 |     monitorEvent = (virDomainQemuMonitorEventPtr) event;
      |                    ^

Forcing 8-byte alignment on virObjectEventPtr removes the
alignment increase during casts to subclasses.

      qemucapabilitiestest: Bump qemu-5.1 capabilities for x86_64 · 031a6be1
      由 Peter Krempa 提交于 
      QEMU added the machine types for the 5.1 release so let's update them.

Other notable changes are 'cpu-throttle-tailslow' migration property,
'zlib' compression for qcow2 images and absrtact socket support.

      virxml: Don't overwrite ctxt->node · 52351030
      由 Michal Privoznik 提交于 
      This reverts b897973f

Even though it may have been the case in the past, relative
XPaths don't overwrite the ctxt->node. Thus, there's no need to
save it.

      security: don't fail if built without attr support · 55029d93
      由 Christian Ehrhardt 提交于 
      If built without attr support removing any image will trigger
 qemuBlockRemoveImageMetadata (the one that emits the warning)
   -> qemuSecurityMoveImageMetadata
     -> virSecurityManagerMoveImageMetadata
       -> virSecurityDACMoveImageMetadata
         -> virSecurityDACMoveImageMetadataHelper
           -> virProcessRunInFork (spawns subprocess)
             -> virSecurityMoveRememberedLabel

In there due to !HAVE_LIBATTR virFileGetXAttrQuiet will return
ENOSYS and from there the chain will error out.

That is wrong and looks like:
  libvirtd[6320]: internal error: child reported (status=125):
  libvirtd[6320]: Unable to remove disk metadata on vm testguest from
  /var/lib/uvtool/libvirt/images/testguest.qcow (disk target vda)

This change makes virSecurityDACMoveImageMetadataHelper and
virSecuritySELinuxMoveImageMetadataHelper accept that
error code gracefully and in that sense it is an extension of:
5214b2f1 "security: Don't skip label restore on file systems lacking XATTRs"
which does the same for other call chains into the virFile*XAttr functions.
