Description Pavel Hrdina 2013-08-21 08:31:14 UTC

Description of problem:
A migration of the guest fails with an error message using dname parameter to change the name of the guest.

Version-Release number of selected component (if applicable):
upstream c753749c27fb48d481e64953d59668731e5e2dbd

How reproducible:
always

Steps to Reproduce:
1. prepare any guest for migration

2. run the command 'virsh migrate --live --domain migr-test --desturi qemu+ssh://ip.address/system --dname migr-test2'

Actual results:
error: internal error: Incoming cookie data had unexpected name migr-test vs migr-test2

Expected results:
The migration should finish successfully without an error.

Comment 2 Jiri Denemark 2013-09-04 07:49:31 UTC

This is now fixed upstream by v1.1.2-43-g8d67c55:

commit 8d67c550e931f1dbc163e7e20784218edc1165df
Author: Jiri Denemark <jdenemar>
Date:   Tue Sep 3 15:17:03 2013 +0200

    qemu: Make domain renaming work during migration
    
    https://bugzilla.redhat.com/show_bug.cgi?id=999352
    
    Since commit v1.0.5-56-g449e6b1 (Pull parsing of migration xml up into
    QEMU driver APIs) any attempt to rename a domain during migration fails
    with the following error message:
    
        internal error Incoming cookie data had unexpected name DOM vs DOM2
    
    This is because migration cookies always use the original domain name
    and the mentioned commit failed to propagate the name back to
    qemuMigrationPrepareAny.

Comment 4 zhe peng 2013-09-09 03:35:02 UTC

Can reproduct this with:
libvirt-1.1.1-2.el7.x86_64

verify with build:
libvirt-1.1.1-4.el7

step:
1:prepare migration env.
2:in source, start a guest
#virsh list --all
Id    Name                           State
----------------------------------------------------
 3     rhel7                          running

3: do migration
# virsh migrate --live --domain rhel7 --desturi qemu+ssh://$DST_ip/system --dname rhel-mig

4: no error occured, check guest on DST
# virsh list --all
 Id    Name                           State
----------------------------------------------------
 2     rhel-mig                       running

move to verified.
