Comment 1 John Ferlan 2021-11-23 20:40:02 UTC 
Juan - please update https://gitlab.com/redhat/rhel/src/qemu-kvm/qemu-kvm/-/merge_requests/57 to use *this* bug for resolution (and then move this one to POST).  I will move the other one to RHEL 8.6.0...
Comment 2 Juan Quintela 2021-11-24 14:21:04 UTC 
I just did.

But I can't see a difference between this bugzilla 2025604 and 2025609 (notice that the last digits are 4 or 9).
I see that they refer to the same bug.

Or I am missing something obvious here.
Comment 3 Juan Quintela 2021-11-24 14:21:51 UTC 
Scratch that.

Both are for 8.5.z, but different bugzillas.  I was looking at the flags only right now.

Sorry for the noise.
Comment 4 John Ferlan 2021-11-24 16:22:30 UTC 
Phew - had me concerned for a moment that I used the wrong bug to write the message ;-/ - I usually have all the bugs open in tabs, then get distracted and have to figure out what I was doing again!   FWIW: tip - if you want to create a link another bug use bug #### and bugzilla will create the link, e.g. bug 2025609 (looks like text when I enter, but when I save a link is created).

QE bot(pre verify): Set 'Verified:Tested,SanityOnly' as gating/tier1 test pass.

Test offline migration with multifd enabled on qemu-kvm-6.0.0-33.module+el8.5.0+13514+2c386966.1.x86_64.
Migration will fail and hmp will give error. But guest still works well on host after migration failed.
1) src qmp
{"execute":"migrate", "arguments":{"uri": "exec:gzip -c > STATEFILE.gz"}}
{"return": {}}
{"execute":"query-migrate"}
{"return": {"blocked": false, "status": "failed"}}
2) src hmp:
(qemu) multifd is not supported by current protocol


Before fixed qemu-kvm-6.0.0-33.module+el8.5.0+13041+05be2dc6.x86_64, qemu will core dump.
(qemu) 1.sh: line 45: 21825 Segmentation fault      (core dumped) /usr/libexec/qemu-kvm -name "mouse-vm" -sandbox on -machine q35 -cpu EPYC -nodefaults


So I would mark this bz as verified per above test results.
