Hi,

I'm launching 16cirros Vm's per user. I see this issue usually when the number of users are more, something like 8+ users. I have a heat template with 16 Cirros resources. Upon launching it using a script, for some users the cirros instances doesn't get the ip address. So say for user 8th I can see couple of vm have the ip address and other 14 vms have their correct ip address assigned.

Setup: 4 node cluster. 2 compute nodes.

Any help is appreciated.
