Public bug reported:
Version:
Kilo
When I was trying to build instance indicating server group on my child cell, I
used the following command:
nova boot --flavor m1.tiny --image cirros-0.3.4-x86_64 --nic
net-id=59c9203b-61a4-44a7-9ccf-76894e270092 test1 --hint
target_cell='api_cell!child_cell' --
hint group=d37a1bcc-51fb-47de-81f3-113b96c5368f
But build failed because child cell can't find the group server id. Here
are logs in nova-conductor.log:
