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.
