Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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.

Description jingzhao 2017-05-09 09:18:02 UTC 
Created attachment 1277339 [details]
dmesg log of dst

Description of problem:
scsi controller unplug failed after migration

Version-Release number of selected component (if applicable):
qemu-kvm-rhev-2.9.0-3.el7.x86_64
kernel-3.10.0-663.el7.x86_64

How reproducible:
3/3

Steps to Reproduce:
1.Boot guest with qemu cli in src [1]
2.Hot-plug virtio scsi disk through qmp
{"execute":"__com.redhat_drive_add", "arguments": {"file":"/home/test/rhel/block1.qcow2","format":"qcow2","id":"drive_datadisk0"}}
{"return": {}}
{"execute":"device_add","arguments":{"driver":"virtio-scsi-pci","id":"scsi1","bus":"root2"}}
{"return": {}}
{"execute":"device_add","arguments":{"driver":"scsi-hd","drive":"drive_datadisk0","id":"device_datadisk0","bus":"scsi1.0"}}
{"return": {}}
{"execute":"__com.redhat_drive_add", "arguments": {"file":"/home/test/rhel/block2.qcow2","format":"qcow2","id":"drive_datadisk1"}}
{"return": {}}
{"execute":"device_add","arguments":{"driver":"virtio-scsi-pci","id":"scsi2","bus":"root1"}}
{"return": {}}
{"execute":"device_add","arguments":{"driver":"scsi-hd","drive":"drive_datadisk1","id":"device_datadisk1","bus":"scsi2.0"}}
{"return": {}}

3.Boot guest with qemu cli in dst [2]

4.Migration from src to dst
(qemu) migrate -d tcp:10.66.6.246:5800
      
(qemu) migrate_set_downtime 1
  
(qemu) migrate_set_speed 1G

5.After migrate finished, unplug scsi disk and scsi controller in dst

6.Check the scsi controller in guest
[root@localhost ~]# lspci -vvv -t

Actual results:
Disk unplug successfully , but scsi controller unplug failed

dmesg log, please check the attachment

Expected results:
Disk and scsi controller unplug successfully 

Additional info:

Can this be reproduced with libvirt commands?
Comment 5 Fam Zheng 2017-06-14 13:14:05 UTC 
To answer myself: looks like yes. Seems the same issue with bug 1455150. Marking TestOnly and keeping the flags back in sync. Sorry for the noise.
