[libvirt] [PATCH 0/6] qemu: Allow suppressing some errors in qemu bulk stats code

Posted by Peter Krempa 4 years, 8 months ago

There is an bugreport [1] that some Openstack deployments get periodic
errors in the log. This is most probably from the bulk stats code which
in some cases calls into the storage backends to update some aspects of
storage volumes. Since none of the errors are fatal add code to allow
skipping them.

[1] https://bugzilla.redhat.com/show_bug.cgi?id=1724808

Peter Krempa (6):
  util: Export virStorageFileSupportsBackingChainTraversal
  qemu: Allow skipping some errors in qemuDomainStorageOpenStat
  util: storagefile: Don't report errors from
    virStorageSourceUpdatePhysicalSize
  qemu: driver: Improve error suppression in
    qemuDomainStorageUpdatePhysical
  qemu: Allow suppressing errors from qemuStorageLimitsRefresh
  qemu: Don't report some ignored errors in
    qemuDomainGetStatsOneBlockFallback
