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 Jeff Nelson 2017-01-13 16:43:29 UTC 
Description of problem:
The package tuned-profiles-nfv contains the profile definitions for realtime-virtual-host and realtime-virtual-guest. This package has a dependency on qemu-kvm-tools-rhev. The reason for this dependency is so ensure the image named tscdeadline_latency.flat (in /usr/share/qemu-kvm) is installed. This image is needed to set up the profile called realtime-virtual-host.

The tscdeadline_latency.flat image is not needed to set up the realtime-virtual-guest profile, but--because the dependency exists--the guest must also install qemu-kvm-tools-rhev.

This is problematic for our customers, because it requires them to install an unnecessary package in the guest. It's problematic for some internal processes as well.

Please split tuned-profiles-nfv into host- and guest-specific packages; the dependency on qemu-kvm-tools-rhev should only be on the package containing the realtime-virtual-host profile.

Version-Release number of selected component (if applicable):
tuned-profiles-nfv-2.7.1-3.el7_3.1.noarch


How reproducible:
Install tuned-profiles-nfv

Steps to Reproduce:
1. yum install tuned-profiles-nfv

Actual results:
qemu-kvm-tools-rhev is also installed.

Expected results:
qemu-kvm-tools-rhev is a dependency only for the realtime-virtual-host profile. It is not a dependency for the realtime-virtual-guest profile.

Additional info:
Comment 1 Jaroslav Škarvada 2017-03-30 09:13:14 UTC 
I am going to resolve it the following way:
- add tuned-profiles-nfv-host and tuned-profiles-nfv-guest packages
- keep tuned-profiles-nfv package which will only require tuned-profiles-nfv-host and tuned-profiles-nfv-guest for backward compatibility

Comment 4 Tereza Cerna 2017-04-11 12:21:19 UTC 
============================
Verified in:
    tuned-2.8.0-1.el7.noarch
PASS
============================

1] If I want only profile realtime-virtual-guest, I can install only tuned-profiles-nfv-guest package without any dependency.

  # yum install tuned-profiles-nfv-guest
  ...
  Installing:
   tuned-profiles-nfv-guest   noarch   2.8.0-1.el7    /tuned-profiles-nfv-guest-2.8.0-1.el7.noarch   2.4 k
  ...


2] If I want profile realtime-virtual-host, it needs also missing dependency qemu-kvm-tools-rhev

  # yum install tuned-profiles-nfv-host
  ...
  Installing:
   tuned-profiles-nfv-host noarch 2.8.0-1.el7            /tuned-profiles-nfv-host-2.8.0-1.el7.noarch 6.3 k
  Installing for dependencies:
   qemu-kvm-tools-rhev     x86_64 10:2.6.0-28.el7_3.6    rhel-7-server-rhev-mgmt-agent-rpms          291 k
  ...


3] If I want to install an old package tuned-profiles-nfv, it installs also packages tuned-profiles-nfv-{guest,host} profiles and missing dependency qemu-kvm-tools-rhev. Package tuned-profiles-nfv still exists because of backward compatibility.

  # yum install tuned-profiles-nfv
  ...
  Installing:
   tuned-profiles-nfv       noarch 2.8.0-1.el7          /tuned-profiles-nfv-2.8.0-1.el7.noarch       279  
  Installing for dependencies:
   tuned-profiles-nfv-guest noarch 2.8.0-1.el7          /tuned-profiles-nfv-guest-2.8.0-1.el7.noarch 2.4 k
   tuned-profiles-nfv-host  noarch 2.8.0-1.el7          /tuned-profiles-nfv-host-2.8.0-1.el7.noarch  6.3 k
   qemu-kvm-tools-rhev      x86_64 10:2.6.0-28.el7_3.6  rhel-7-server-rhev-mgmt-agent-rpms           291 k
  ...


Tested in:
  # rpm -q tuned qemu-kvm-tools-rhev
  tuned-2.8.0-1.el7.noarch
  qemu-kvm-tools-rhev-2.6.0-28.el7_3.6.x86_64
