1057407 – Migrate guest with Error starts the paused guest.

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 hyao@redhat.com 2014-01-24 02:48:31 UTC

Description of problem:
Migrate guest with Error starts the paused guest.

Version-Release number of selected component (if applicable):
# rpm -qa libvirt
libvirt-1.1.1-18.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
Use the tree http://download.englab.nay.redhat.com/pub/rhel/rel-eng/RHEL-7.0-20140116.1/compose/Server/x86_64/os/ to get two hosts A and B.
Prepare the guest on nfs pool do the following steps on host A and B.
1. On host A:
# virsh list --all
 Id    Name                           State
----------------------------------------------------
 3     mig2                           running
 
Migrate the guest with --suspend option from A to B.
[root@4-116 ~]# virsh migrate mig2 --live qemu+ssh://hostb/system --verbose --suspend
root@hostb's password:
Migration: [100 %]
[root@4-116 ~]# virsh list --all
 Id    Name                           State
----------------------------------------------------
 -     mig2                           shut off

Starts the guest after the migration is done.
[root@4-116 ~]# virsh start mig2  ==> this step is not common.
Domain mig2 started


2. On hostB.

# virsh list --all
 Id    Name                           State
----------------------------------------------------
 10    mig2                           paused

Try to migrate the guest back from B to A with --suspend option
[root@7-204 ~]# virsh migrate mig2 --live qemu+ssh://hosta/system --verbose --suspend
root@hosta's password:
error: Requested operation is not valid: domain is already active as 'mig2' ===> it's right we got the error here.

[root@7-204 ~]# virsh list --all
 Id    Name                           State
----------------------------------------------------
 10    mig2                           running   ==> it doesn't make sense that the error turn on the paused guest.

    qemu: keep pre-migration domain state after failed migration

Comment 5 zhe peng 2014-02-13 09:35:28 UTC

I can reproduce this with libvirt-1.1.1-22.el7.x86_64

verify with build :libvirt-1.1.1-23.el7.x86_64

step:
 1 same with bug description
 2 # virsh migrate rhel7 --live qemu+ssh://$source_IP/system --verbose --suspend
error: Requested operation is not valid: domain is already active as 'rhel7'

 on DST: # virsh list --all
 Id    Name                           State
----------------------------------------------------
 4     rhel7                          paused
 the guest state not changed, move to verified.
