Comment 1 Red Hat Bugzilla Rules Engine 2017-05-30 08:27:03 UTC

This bugzilla has been removed from the release and needs to be reviewed and Triaged for another Target Release.

Comment 2 Martin Schuppert 2017-05-30 08:29:50 UTC

This behavior is still present on OSP10

0) start instance on compute1
1) poweroff compute1
2) evacuate to compute2
3) poweron compute1
4) live migrate from compute2 to compute1
=> migration fails with

5) (workaround) live migrate again from compute2 to compute1
=> successful migration
