1024393 – libvirt-daemon-lxc kind of heavy on the dependencies.

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 Bhavna Sarathy 2013-10-29 15:01:48 UTC

Please add this fix into RHEL 7.0 that will reduce the libvirt-lxc dependencies 

+++ This bug was initially created as a clone of Bug #1012198 +++

From the basically-minimal Fedora 20 Cloud image, installing libvirt-daemon-lxc pulls in.... kind of a lot of stuff. Could we reduce this? It would be nice for the purpose of having a cloud image which runs containers. The more lightweight the "outer shell" can be, the more room there is for the actual contents.


I'd prefer the advantages of libvirt lxc over the lxc tools, but, this is literally 150x bigger.

List of deps follows.

This has a 1.5 meg ChangeLog.gz, and 15 megs of translations. That seems a bit large...

Also kind of large, does libvirt really depend on Ceph?

The changelog is moved into -devel in current builds so won't impact. There's not really anything we can do about translations unless we want to screw over non-english speakers.

Yes, the storage management features use ceph.

Update: something is now pulling in Avahi. I *really* don't want avahi on the cloud image.

--- Additional comment from Alexander Larsson on 2013-10-08 04:31:52 EDT ---

avahi daemon, or avahi libs?

--- Additional comment from Daniel Berrange on 2013-10-08 05:01:08 EDT ---

libvirt only depends on avahi-libs, so if something is pulling in the daemon, it isn't libvirt directly.

--- Additional comment from Matthew Miller on 2013-10-08 07:56:57 EDT ---

avahi-libs now pulls in avahi daemon -- that's bug #913168, apparently.

--- Additional comment from Daniel Berrange on 2013-10-08 10:02:40 EDT ---

Oh actually, I just noticed you are installing the high level libvirt lxc package:

> Installing:
>   libvirt-daemon-lxc              x86_64 1.1.2-3.fc20      updates-testing  34 

At the cost of breaking many libvirt APIs you could switch to installing the finer grained package  'libvirt-daemon-driver-lxc'. That would pull in just the lxc hypervisor APIs, which is closer in terms of functionality to the lxc tools. 

Of course if the app using libvirt needs to use non-hypervisor APIs, you're still doomed because it'll need to pull in the other libvirt-daemon-driver-* packages anyway.  It also might lead to bug reports from users who find that various parts of libvirt are non-functional, so not sure whether its a good idea for the cloud image or not really.

--- Additional comment from Matthew Miller on 2013-10-08 15:41:03 EDT ---

I was excited about that suggestion for a minute, but it turns out that if I just do `yum install libvirt-daemon-driver-lxc`, everything is pulled in except

  hwdata
  libpciaccess
  libvirt-daemon-driver-interface
  libvirt-daemon-driver-nodedev
  libvirt-daemon-driver-nwfilter
  libvirt-daemon-driver-secret
  libvirt-daemon-driver-storage
  libvirt-daemon-lxc

So basically it looks like everything is pulled in _except_ the APIs. This saves about 5MB -- two megabytes compressed -- and doesn't really address the security-respin concern. So I think we're better off with the higher-level unless we can somehow make that have a significant impact.

Thanks for the idea, though!

Smells like something is wrong there then. All those storage related deps like ceph/gluster/etc should only be required by the libvirt-daemon-driver-storage sub-RPM.

libvirt-daemon-driver-lxc requires libvirt-daemon, and then that pulls in all the other stuff.

--- Additional comment from Daniel Berrange on 2013-10-09 08:30:16 EDT ---

Ok, that definitely sounds broken then. The libvirt-daemon package itself should be pretty minimal on deps since it only really contains RPC code.

--- Additional comment from Daniel Berrange on 2013-10-29 07:56:02 EDT ---

This patch removes the many bogus deps from the libvirt-daemon RPM, pushing them down to the libvirt-daemon-driver-XXXX RPMs which actually require them.

On a Fedora 19 host, I installed a minimal container using

 # yum -y --releasever=19 --nogpg --installroot=/var/lib/libvirt/filesystems/libvirtsize1 \
          --disablerepo='*' --enablerepo=fedora install \
          systemd passwd yum fedora-release vim-minimal openssh-server procps-ng

And then installed just 'libvirt-daemon-driver-lxc' - this pulls in libvirt-daemon-driver-network, libvirt-daemon and libvirt-client.

With the existing packaging I see this size usage

# du -h -c -s /var/lib/libvirt/filesystems/libvirtsize1
453M	/var/lib/libvirt/filesystems/libvirtsize1
453M	total

With the patch applied, we save 41 MB:

# du -h -c -s /var/lib/libvirt/filesystems/libvirtsize2
412M	/var/lib/libvirt/filesystems/libvirtsize2
412M	total

The following packages are now, no longer required in the minimal install

I don't think we can get much smaller than this without either major code changes to libvirt, or improvements to RPM to allow exclusion of things like translations without breaking upgrades

--- Additional comment from Daniel Berrange on 2013-10-29 07:57:41 EDT ---

Oh, note that since I used F19 for this test, it still has the 1.5 MB changelog.gz file present, that is gone in rawhide/f20.

Comment 1 Bill Nottingham 2013-10-29 15:11:56 UTC

Additional note for RHEL: unlike Fedora, where all built things end up in the repo, if we're changing the dependency stack in RHEL we need to ensure that the proper bits still end up in the product where necessary.

Comment 2 Daniel Berrangé 2013-10-29 15:15:28 UTC

We're not changing the overall dependency stack of libvirt. This is merely moving some deps out of 'libvirt-daemon' and into 'libvirt-daemon-driver-XXX'. Overall the total number of deps is unchanged. This just allows someone doing 'yum install libvirt-daemon-driver-lxc' to get few bits pulled in by default.

Comment 3 Daniel Berrangé 2013-10-29 15:18:28 UTC

Fix available upstream

commit 23142ac91a86309214923f446be9d0dd54d99d95
Author: Daniel P. Berrange <berrange>
Date:   Tue Oct 29 11:27:45 2013 +0000

    Push RPM deps down into libvirt-daemon-driver-XXXX sub-RPMs
    
    For inexplicable reasons, many of the 3rd party package deps
    were left against the 'libvirt-daemon' RPM when the drivers
    were split out. This makes a minimal install heavier that
    it should be. Push them all down into libvirt-daemon-driver-XXX
    so they're only pulled in when truly needed
    
    With this change applied, a minimal install of just the
    libvirt-daemon-driver-lxc RPM is reduced by 41 MB on a
    Fedora 19 host.

Comment 4 Daniel Berrangé 2013-10-29 15:19:23 UTC

Should also pull in the changelog fix

commit e23216da9a9318df920abb11b02582b81515c862
Author: Cole Robinson <crobinso>
Date:   Wed Sep 25 13:20:40 2013 -0400

    spec: Clean up distribution of ChangeLog (and others)
    
    - Move COPYING* to libvirt-client, so every package pulls them in
    - Move AUTHORS ChangeLog.gz NEWS README TODO from -daemon to -docs
    - Drop duplicate distribution of docs in -python

Comment 7 Luwen Su 2013-11-22 06:34:50 UTC

1.Install a minimal install rhel7 guest , named test
2.Configure tests yum repo , make sure that inclue latest packages
3.
#yum install  libvirt-daemon-lxc
