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.

libvirtd.log
Description of problem:
migration from RHEL6.8 to RHEL7.3 host failed with error "Unsupported migration cookie feature persistent"
Version-Release number of selected component (if applicable):
rhel6.8:
libvirt-0.10.2-59.el6.x86_64
qemu-kvm-rhev-0.12.1.2-2.490.el6.x86_64
rhel7.3:
libvirt-1.3.2-1.el7.x86_64
qemu-kvm-rhev-2.3.0-31.el7.x86_64
How reproducible:
100%
steps to reproduce:
1.Do migration from rhel6.8 to rhel7.3:
#virsh migrate qemu+ssh://10.73.196.125/system --live --verbose
root.196.125's password:
Migration: [ 98 %]error: internal error: Unsupported migration cookie feature persistent
2.Check the libvirtd's log on target host:
#cat /var/log/libvirt/libvirtd.log | grep -i "Unsupported migration cookie feature persistent"
error : qemuMigrationCookieXMLParse:1250 : internal error: Unsupported migration cookie feature persistent
Actual results:
Migration from RHEL6.8 to RHEL7.3 failed with error "Unsupported migration cookie feature persistent"
Expected results:
Migration from RHEL6.8 to RHEL7.3 should be complete correctly.
Additional info:
1.Migration from rhel6.8 to rhel7.2 can be complete correctly.
2.The "Unsupported migration cookie feature persistent" is a result of a bug on RHEL-6 libvirt, which sends persistent XML in the cookie even though VIR_MIGRATE_PERSIST_DEST was not used. But this is harmless. So maybe the rhel7.3 needs to be compatible with it.

Yeh can confirm; just hit the same thing libvirt-0.10.2-60.el6.x86_64->libvirt-1.3.5-1.el7.x86_64
(It does work if I use --persistent on the migrate).

qemu: Fix migration from old libvirt
Older libvirt versions send persistent XML in a migration cookie even
when VIR_MIGRATE_PERSIST_DEST flag is not used, but current libvirt
properly fails if the cookie contains unexpected flags. Thus migration
from old libvirt fails with
internal error: Unsupported migration cookie feature persistent
unless VIR_MIGRATE_PERSIST_DEST flag is set.
