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.

qemu log
Description of problem:
Live migration with ipv6 iSCSI lun failed
Version-Release number of selected component (if applicable):
libvirt-1.1.1-16.el7.x86_64
qemu-kvm-1.5.3-30.el7.x86_64
How reproducible:
100%
Steps to Reproduce:
1.Prepared three machines, one as iscsi target: A, with 2 disks(USB disk is OK).
set the ipv6 address on test machines.
On A: #ifconfig eth0 inet6 add 3ffe::103/64
On B: #ifconfig eth0 inet6 add 3ffe::104/64
On C: # ifconfig eth0 inet6 add 3ffe::105/64
use ping6 to ping each other with ipv6 address, check the network is all right.
2.On A, setup the iscsi target environment.
#tgt-admin --s
Target 1: iqn.20130801.10.66.5.23:target1
System information:
Driver: iscsi
State: ready
I_T nexus information:
LUN information:
LUN: 0
.........................
LUN: 1
Type: disk
SCSI ID: IET 00010001
SCSI SN: beaf11
Size: 1048 MB, Block size: 512
Online: Yes
Removable media: No
Prevent removal: No
Readonly: No
Backing store type: rdwr
Backing store path: /dev/sdb
Backing store flags:
Account information:
ACL information:
ALL
3. On B, C discover the lun exported on machine A successfully
4. On machine B: start a domain with xml below:
<disk type='network' device='lun'>
<driver name='qemu' type='raw'/>
<source protocol='iscsi' name='iqn.2013-10.3ffe.103:iscsi/1'>
<host name='3ffe::103' port='3260'/>
</source>
<target dev='vda' bus='virtio'/>
</disk>
# virsh create test-yy.xml
Domain test-yy created from test-yy.xml
5. do the migration to machine C
# virsh migrate --live --verbose test-yy qemu+ssh://[3ffe::105]/system --unsafe
Actual results:
Domain was destroyed before the migration finished and the following error occurred.
Migration: [ 66 %]error: Domain not found: no domain with matching name 'test-yy'
Expected results:
Migrate successfully
Additional info:
this issue is not related to ipv6.
I cannot reproduce this. Can you try:
(1) using IPv6 only for migration and not for the iSCSI URL
(2) using "virsh save" and "virsh restore" instead of migration?

It was not reproduced on
qemu-kvm-rhev-1.5.3-52.el7.x86_64
libvirt-1.1.1-26.el7.x86_64
Migration was completed without error.
@ (1)
Migration works well using IPv6 with both ISCSI and non-ISCSI disk.
@ (2)
Both save and restore work well.
So maybe it is not a bug.
