Bug 1566000

Try commenting out 

server=qemu:///system

and running again. It should mgirate the guests to the second instance. You should be able to remove the first one once that has happened.

It created the task conflict and it did not migrate any guests:

[0] 17:08 root satotest.brq ~ # virt-who -o -d

However removing virt-who-satotest.gsslab.brq.redhat.com-10 profile and run virt-who -od again helped.

Now there is no virt-who-satotest.gsslab.brq.redhat.com-10 and guests are reported under satotest.gsslab.brq2.redhat.com:

Well, obviously there had to be some change in the code, as this was working with server= line in Satellite 6.2 ....

This needs to go to the Sat6 team to determine the differences (6.2 vs. 6.3) that led to the change in behavior in Comment 3.

Moving to candlepin pile to get determination of behavior change.

Sat 6.2 is 0.9.54
Sat 6.3 is 2.1.14

Will, please let us know what you find wrt whether the issue is in Candlepin.

Would you please separate out the remaining issue as you have suggested. Thank you.

Removing need info. The fix for this will be part of a larger solution.

Can you please add related bugs to "See Also"?

Can you set the fixed in to the package and version that fixes this BZ?

The fix for this issue requires a Candlepin version of 2.5.5+ and a virt-who version of 0.22.2+ or 0.23.0+.

It will not fix old entries but will server to avoid the scenario to happen going forward. It will take care of any of the fabrics where the consumer checks in and the consumer is also a hypervisor that virt-who is reporting on. Setting up this scenario will be the best way to see that the fix is complete.

Mike, based on Eko's comment, I'd like to tentatively dual propose this to 6.4.z. 
I'll keep it out of 6.3.z, as I don't see us bringing this that far back.
