[openstack-dev] [openstack-ansible] [nova] Compute node failing to come up in hypervisor list after first reboot

I've been chasing a problems with a build for some days now and would greatly appreciate any pointers the community can offer.

The build is built of three nodes (infra+storage+compute) each of which is a KVM virtual machine.

After installation everything seems fine. However, after rebooting the compute node the hypervisor list reports it as being down.

The /var/log/nova/nova-compute.log is filling up with messages of the form:

     2017-03-06 14:13:11.209 4380 ERROR oslo.messaging._drivers.impl_rabbit [req-7fa52faa-c21f-4a1c-8413-fddad9e52c2e - - - - -] [fd4c494d-1ef5-4502-991f-521f0a8a2bc3] AMQP server on is unreachable: getrandom() initialization failed. (_ssl.c:590). Trying again in 32 seconds. Client port: None

I can confirm that is in fact reachable from compute1.

Furthermore,  'nc -z -v -w5 5671' reports:

    Connection to 5671 port [tcp/amqps] succeeded!

Any pointers would be greatly appreciated.

Kind regards, Lawrence
