Title:
anti-affinity server boot failure shows stack trace
Status in OpenStack Dashboard (Horizon):
New
Status in OpenStack Compute (Nova):
In Progress
Bug description:
If anti-affinity policy is set for two different servers, and only one
host is available, a stack trace is shown instead of a error message.
Failure is expected, but a message about why it failed would be
helpful.
On a single node devstack setup:
nova server-group-create --policy anti-affinity aagroup
nova boot --flavor m1.nano --image cirros-0.3.1-x86_64-uec --nic net-
id=ea784f2b-b262-451a-821a-5ee7f69b3d63 --hint group=0f2b71ea-3dc3
-423d-a9f4-41ac5d0fff07 server1
nova boot --flavor m1.nano --image cirros-0.3.1-x86_64-uec --nic net-
id=ea784f2b-b262-451a-821a-5ee7f69b3d63 --hint group=0f2b71ea-3dc3
-423d-a9f4-41ac5d0fff07 server2
server1 boots fine
server2 has Status Error and Power State No State
Horizon shows:
Fault
Message
unsupported operand type(s) for |: 'list' and 'set'
