Changelog

Version: 6.0.0-0ubuntu8.20 2024-04-25 15:06:57 UTC

  libvirt (6.0.0-0ubuntu8.20) focal; urgency=medium

  * d/p/u/lp2059272-2-qemu-Wait-qemuProcessReconnect-threads-in-cleanup.patch:
    Remove patch. It is not possible to wait for qemuProcessReconnect()
    in cleanup: it talks to QEMU monitor, which blocks on replies from
    event loop, but it's already stopped at cleanup, delaying shutdown.

  * d/p/u/lp2059272-2-qemu-Do-not-save-XML-in-shutdown-on-init.patch:
    Instead of waiting at cleanup for threads which might be blocked
    thus would _not even reach_ the function that causes the problem,
    just skip that function if it is _actually reached_ while daemon
    shutdown is in progress. That is in the init path and would just
    run again anyway the next time libvirtd is started (LP: #2059272)

  * NOTE: This package contains the changes from 6.0.0-0ubuntu8.18 and
    6.0.0-0ubuntu8.17 in focal-proposed (with symbolic changelog entry)
