I'm gonna submit a patch upstream, but since use-cases I've seen work so far there is no need to hurry or SRU - still doing it right is the right thing to do.

Changed in libvirt (Ubuntu):
status:	New → Triaged
importance:	Undecided → Low

This bug was fixed in the package libvirt - 4.0.0-1ubuntu1

---------------
libvirt (4.0.0-1ubuntu1) bionic; urgency=medium

  * Merged with Debian unstable (4.0)
    This closes several bugs:
    - Error generating apparmor profile when hostname contains spaces
      (LP: #799997)
    - qemu 2.10 locks files, libvirt shared now sets share-rw=on (LP: #1716028)
    - libvirt usb passthrough throws apparmor denials related to
      /run/udev/data/+usb (LP: #1727311)
    - AppArmor denies access to /sys/block/*/queue/max_segments (LP: #1729626)
    - iohelper improvements to let bypass-cache work without opening up the
      apparmor isolation (LP: #1719579)
    - nodeinfo on s390x to contain more CPU info (LP: #1733688)
    - Upgrade libvirt >= 4.0 (LP: #1745934)
  * Remaining changes:
    - Disable libssh2 support (universe dependency)
    - Disable firewalld support (universe dependency)
    - Disable selinux
    - Set qemu-group to kvm (for compat with older ubuntu)
    - Additional apport package-hook
    - Modifications to adapt for our delayed switch away from libvirt-bin (can
      be dropped >18.04).
      + d/p/ubuntu/libvirtd-service-add-bin-alias.patch: systemd: define alias
        to old service name so that old references work
      + d/p/ubuntu/libvirtd-init-add-bin-alias.patch: sysv init: define alias
        to old service name so that old references work
      + d/control: transitional package with the old name and maintainer
        scripts to handle the transition
    - Backwards compatible handling of group rename (can be dropped >18.04).
    - config details and autostart of default bridged network. Creating that is
      now the default in general, yet our solution provides the following on
      top as of today:
      + autostart the default network by default
      + do not autostart if subnet is already taken (e.g. in guests).
    - d/p/ubuntu/Allow-libvirt-group-to-access-the-socket.patch: This is
      the group based access to libvirt functions as it was used in Ubuntu
      for quite long.
      + d/p/ubuntu/daemon-augeas-fix-expected.patch fix some related tests
        due to the group access change.
    - ubuntu/parallel-shutdown.patch: set parallel shutdown by default.
    - d/p/ubuntu/enable-kvm-spice.patch: compat with older Ubuntu qemu/kvm
      which provided a separate kvm-spice.
    - d/p/ubuntu/ubuntu-libxl-qemu-path.patch: this change was split. The
      section that adapts the path of the emulator to the Debian/Ubuntu
      packaging is kept.
    - d/p/ubuntu/ubuntu-libxl-Fix-up-VRAM-to-minimum-requirements.patch: auto
      set VRAM to minimum requirements
    - d/p/ubuntu/xen-default-uri.patch: set default URI on xen hosts
    - Add libxl log directory
    - libvirt-uri.sh: Automatically switch default libvirt URI for users on
      Xen dom0 via user profile (was missing on changelogs before)
    - d/p/ubuntu/apibuild-skip-libvirt-common.h: drop libvirt-common.h from
      included_files to avoid build failures due to duplicate definitions.

  * Dropped Changes (In Debian/Upstream now based on interim 3.10 work) some of
    these were never released, but important to mention for the bug references:
    - libnss-libvirt once enabled causes apt to call getdents
      avoid this being an issue by dropping a apt conf that allows
      this in seccomp (LP: #1732030).
    - d/libvirt-daemon-system.postrm: clean up more libvirt directories on
      purge

      apparmor implementation of security callback
    - d/p/ubuntu-aa/0046-apparmor-virt-aa-helper-drop-static-channel-rule.patch:
      this is now covered by chardev label callbacks
  * Added Changes:
    - Revert Debian change "Drop libvirt-bin upgrade handling"
      This is needed in Ubuntu one last time (drop >18.04)
    - Revert Debian change "Drop maintscript helpers for versions predating
      jessie and wheezy-backports". This is needed in Ubuntu one last
      time (drop >18.04)
    - Refreshed d/p/* to match new version (only fuzz, no semantic change)
    - d/libvirt-daemon-system.postrm: change order of libvirt-qemu removal
      to avoid error messages on purge
    - remove no more used libvirt-dnsmasq user (drop >18.04)
    - d/p/ubuntu-aa/0040-apparmor-add-mediation-rules-for-unconfined.patch:
      apparmor: add mediation rules for unconfined guests

      add multipass image path and mark as ubuntu only change.
    - d/rules: install virtlockd correctly with defaults file (LP: #1729516)
    - extended d/p/0025-apparmor-fix-newer-virt-manager-1.4.0.patch to cover
      the slightly changed behavior of libvirt 4.0 (LP: #1741617)
    - d/control: make libvirt-daemon-driver-storage-rbd a recommend instead of
      just a suggest to have 3rd party relying on rbd out of the box working.
      This is deprecated and users of rbd backend should start depending on
      this package for it will be dropped to a suggest in future releases.
