2236500 – libvirt-daemon marked for autoremoval after upgrade

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Andrea Bolognani 2023-08-31 13:11:06 UTC

+++ This bug was initially created as a clone of Bug #2232805 +++

As of RHEL 9.2, the libvirt-daemon package (which contains the
libvirtd daemon) is a hard dependency for hypervisor metapackages
such as libvirt-daemon-kvm.

In RHEL 9.3, this dependency has been dropped, with the intention of
making it possible to create minimal deployments where the monolithic
daemon is not present at all.

Unfortunately, this decision causes problems on upgrade for
deployments that were manually switched from modular daemons (the
default in RHEL 9) to monolithic daemon.

More specifically, while the upgrade itself would be successful and
libvirtd would still be available after it, a subsequent call to 'yum
autoremove' would result in the libvirt-daemon package being removed
and the deployment breaking.

Comment 1 Andrea Bolognani 2023-08-31 13:12:31 UTC

Fix pushed upstream.

  commit aa5895cbc72bd9b4bb1ce99e231b2ac4b25db9c4
  Author: Andrea Bolognani <abologna>
  Date:   Wed Aug 30 17:45:47 2023 +0200

    rpm: Recommend libvirt-daemon for with_modular_daemons distros
    
    A default deployment on modern distros uses modular daemons but
    switching back to the monolithic daemon, while not recommended,
    is still considered a perfectly valid option.
    
    For a monolithic daemon deployment, the upgrade to libvirt 9.2.0
    or newer works as expected; a subsequent call to dnf autoremove,
    however, results in the libvirt-daemon package being removed and
    the deployment no longer working.
    
    In order to avoid that situation, mark the libvirt-daemon as
    recommended.
    
    This will unfortunately result in it being included in most
    installations despite not being necessary, but considering that
    the alternative is breaking existing setups on upgrade it feels
    like a reasonable tradeoff.
    
    Moreover, since the dependency on libvirt-daemon is just a weak
    one, it's still possible for people looking to minimize the
    footprint of their installation to manually remove the package
    after installation, mitigating the drawbacks of this approach.

# rpm -q libvirt-daemon
libvirt-daemon-9.5.0-6.el9.x86_64

libvirt-daemon is not removed after upgrade.

Comment 8 Lili Zhu 2023-09-05 23:58:23 UTC

When I try to reproduce this bug for the second time, After upgrade, before execute the "yum autoremove", I reboot the host firstly,
After the reboot:
libvirt-daemon-9.5.0-6.el9.x86_64

# yum autoremove

Comment 11 Lili Zhu 2023-09-06 08:18:03 UTC

Produce this bug by upgrading from RHEL8 to RHEL9:
1. install virt module on RHEL8
# yum module install virt

2. check whether there are libvirt and libvirt-daemon packages
# rpm -q libvirt
package libvirt is not installed
# rpm -q libvirt-daemon
libvirt-daemon-9.5.0-6.el9.x86_64

(libvirt is not installed)

3. upgrade to rhel9.3

4. execute autoremove
# yum autoremove

> > Hi, Andrea

No, that bug is unrelated. The issue was introduced by the rebase to
libvirt 9.2.0, which is the first upstream version where it was made
possible for the libvirt-daemon package to be uninstalled without
taking the rest of libvirt with it.

Correct.

Right. The libvirt packages has a hard dependency on *all*
subpackages, including libvirt-daemon, so if you have installed it
then it will not be possible for you to pick and choose which parts
you want to keep and which ones you want to remove.

Usually you'd go for a more targeted setup; specifically, for a host
that's going to be a QEMU-based hypervisor, you'd install the
libvirt-daemon-kvm package, which depends on all the libvirt
components needed to make qemu:///system work, as well as qemu-kvm
itself, but none of the other drivers like LXC or Xen.

The libvirt-daemon-kvm package *does not*, as of libvirt-9.5.0-6.el9,
have a dependency on the libvirt-daemon package, so if you have set
up your machine by installing it you should be able to reproduce the
issue this bug report is about after upgrade.

Great. I will preverify this bug with the method you mentioned. Thanks very much.

Tiny clarification: virsh will connect to libvirtd, not virtqemud.

Since the machine was installed with RHEL 8, which uses the
monolithic daemon (libvirtd) by default, and we intentionally don't
change things around on package upgrade, even after the upgrade to
RHEL 9 it will still use libvirtd despite RHEL 9 using the modular
daemon (virtqemud) by default.

Thanks!
