Created attachment 1139508 [details] 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). Dave

Fixed upstream by commit 338f772e923ce07148abe6dcaf3d62b744e7baf5 Refs: v2.0.0-165-g338f772 Author: Jiri Denemark <jdenemar> AuthorDate: Mon Jul 18 13:17:28 2016 +0200 Commit: Jiri Denemark <jdenemar> CommitDate: Mon Jul 18 17:38:03 2016 +0200 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. https://bugzilla.redhat.com/show_bug.cgi?id=1320500 Signed-off-by: Jiri Denemark <jdenemar>
I can reproduce this BZ on build: RHEL6.8: libvirt-0.10.2-59.el6.x86_64 qemu-kvm-rhev-0.12.1.2-2.491.el6.x86_64 RHEL7.3: libvirt-2.0.0-2.el7.x86_64 qemu-kvm-rhev-2.6.0-18.el7.x86_64 Verify this BZ on build: RHEL7.3: libvirt-2.0.0-4.el7.x86_64 qemu-kvm-rhev-2.6.0-18.el7.x86_64 Migration succeeds and guest disappears after destroyed on target
