[libvirt PATCH v2 0/4] qemu: Only raise memlock limit if necessary

[Andrea Bolognani]

This feature has been requested by KubeVirt developers and will make
it possible for them to make some VFIO-related features, such as
migration and hotplug, work correctly.

  https://bugzilla.redhat.com/show_bug.cgi?id=1916346

Changes from [v1]:

  * prep patches have been pushed;

  * parsing /proc file is now explicitly restricted to Linux only
    and only uses safe libvirt helpers;

  * the qemu.conf knob has been dropped in favor of adopting a
    behavior that should work correctly in all scenarios.

[v1] https://listman.redhat.com/archives/libvir-list/2021-March/msg00293.html

Andrea Bolognani (4):
  util: Try to get limits from /proc
  qemu: Don't ignore virProcessGetMaxMemLock() errors
  qemu: Refactor qemuDomainAdjustMaxMemLock()
  qemu: Only raise memlock limit if necessary
