Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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 of problem:
Two tracebacks were appeared during testing of realtime profiles (component tuned). First was generated in /var/log/tuned/tuned.log by command `tuned-adm verify` on realtime-virtual* profiles.
Second traceback was created when some realtime-virtual* profile was active and user decided to select other profile.
Problem exists for all realtime profiles (realtime-virtual-host, realtime-virtual-guest) from package tuned-profiles-nfv.
Version-Release number of selected component (if applicable):
tuna-0.11.1-12.el7_2.noarch
tuned-2.7.1-2.el7.noarch
tuned-profiles-nfv-2.7.1-2.el7.noarch
qemu-kvm-tools-rhev-2.3.0-31.el7_2.21.x86_64
Steps to Reproduce:
# systemctl status tuned | grep Active
Active: active (running) since Wed 2016-08-24 07:00:50 CEST; 35min ago
# tuned-adm active
Current active profile: balanced
# tuned-adm profile realtime-virtual-host
# tuned-adm verify
>>> see traceback in /var/log/tuned/tuned.log

Actual results:
two tracebacks was appeared in /var/log/tuned/tuned.conf
Expected results:
no tracebacks
---------------------------------------------------
Traceback are copied from BZ#1369791 (tuned).
From comment c#6 (jskarvad):
"I will take a look, but it's probably minor problem. You need to setup "isolated_cores" in: "/etc/tuned/realtime-virtual-host-variables.conf" and "/etc/tuned/realtime-virtual-guest-variables.conf" to sane values and your machine needs to be multicore with enough cores to satisfy your request. One backtrace is even from the Tuna tool, so you could also open bug against Tuna to cleanly exit instead of traceback if invalid cpustring is provided (e.g. '}'). Nevertheless, the Tuned profile should be fixed not to traceback."
