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:
guest will have broken settings if we do not specify scheduler in iothreadsched element, which will make guest disappear after restart libvirtd
Version-Release number of selected component (if applicable):
libvirt-1.2.16-1.el7.x86_64
How reproducible:
100%
Steps to Reproduce:
1. edit domain xml (with --skip-validate) like this:
# virsh edit test4 --skip-validate
<cputune>
<vcpusched vcpus='0-2,4'/>
<iothreadsched iothreads='1-2'/>
</cputune>
2. recheck the xml
# virsh dumpxml test4
<cputune>
<vcpusched vcpus='0-2,4' scheduler='none'/>
<iothreadsched iothreads='1-2' scheduler='none'/>
</cputune>
3. restart libvirtd
# service libvirtd restart
Redirecting to /bin/systemctl restart libvirtd.service
# virsh dumpxml test4
error: failed to get domain 'test4'
error: Domain not found: no domain with matching name 'test4'
Actual results:
libvirt generate a invalid guest xml in step 1
Expected results:
just drop this xml because it doesn't contain any useful information

conf: Enforce scheduler name when parsing XML
We require the scheduler name attribute in the schemas but the code
would actually be fine when it was omitted. Make it mandatory.
