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.

qemu: move virDomainLiveConfigHelperMethod right after BeginJob
We should call virDomainLiveConfigHelperMethod ASAP because this
function transfers VIR_DOMAIN_AFFECT_CURRENT to VIR_DOMAIN_AFFECT_LIVE
or VIR_DOMAIN_AFFECT_CONFIG. All other additional checks for those two
flags should consider that the user give us VIR_DOMAIN_AFFECT_CURRENT.
Remove the unnecessary check whether the domain is live in case of
VIR_DOMAIN_VCPU_GUEST because this check is done by
virDomainLiveConfigHelperMethod.

Verify this bug with libvirt-1.2.17-2.el7.x86_64:
1. prepare a offline guest:
# virsh domstate r6
shut off
2. do setvcpus with no option:
# virsh setvcpus r6 5
error: Requested operation is not valid: domain is not running
# virsh setvcpus r6 5 --live
error: Requested operation is not valid: domain is not running
