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 Ján Tomko 2014-01-07 12:50:50 UTC 
Description of problem:
The listen address attribute is ignored by peer-to-peer migration.

Version-Release number of selected component (if applicable):
libvirt-1.1.1-16.el7

How reproducible:
Certainly.

Steps to Reproduce:
1. Do a peer-to-peer migration with a listen address that the destination can't use:
virsh migrate --live --p2p --listen-address 1.2.3.4 cake qemu+ssh://dest/system

Actual results:
Migration succeeds.

Expected results:
Migration fails because of the listen address:
qemu-kvm: -incoming tcp:1.2.3.4:49152: Failed to bind socket: Cannot assign requested address

Comment 3 zhoujunqin 2014-01-24 03:04:15 UTC 
I can reproduce this bug with the reproducer in bug destription with libvirt-1.1.1-16.el7, and I could get the expect error after i update the libvirt to the  libvirt-1.1.1-19.el7,so this bug can be marked verified.

Reproduce steps
1. start a guest for migration
2.do a peer-to-peer migration with a listen address that the destination can't use:
# virsh migrate --live --p2p --listen-address 1.2.3.4 raw qemu+ssh://$ip/system
Migration succeeds.

Verify steps
1.start a guest for migration
# virsh list 
 Id    Name                           State
----------------------------------------------------
 6     raw                            running
2.do a peer-to-peer migration with a listen address that the destination can't use:
# virsh migrate --live --p2p --listen-address 1.2.3.4 raw qemu+ssh://$ip/system
error: internal error: early end of file from monitor: possible problem:
qemu-kvm: -incoming tcp:1.2.3.4:49152: Failed to bind socket: Cannot assign requested address
3.do a peer-to-peer migration with a listen address that the destination can use:
# virsh migrate --live --p2p --listen-address $ip  raw qemu+ssh://$ip/system
Migration succeeds.
4.do a peer-to-peer migration without listen address
# virsh migrate --live --p2p raw  qemu+ssh://$ip/system
Migration succeeds.
