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