Hi,

Pike Nova Compute service hangs on "Loading compute driver"

more details/logs here:

http://paste.openstack.org/raw/yQdPex...

Fresh install of Windows server 2016 Datacenter edition, OVS agent only (without live migration, ceilometer, neutron-hyper-agent). Stable OVS 2.7 is installed.

Ocata version is starting correctly on this setup.

Hello,

This sounds a bit peculiar. I'm wondering if it actually hangs while loading the driver (shouldn't be any reasons to), or after it loaded. What kind of OpenStack are you using (RDO, Fuel, DevStack, etc.)?

Also, could you also include the nova.conf file? By default, it is located in: C:\Program Files\Cloudbase Solutions\OpenStack\Nova\etc.

Best regards,

Claudiu Belu


UPDATE:

So, after a little digging around and debugging, we've seen that the driver loads normally. The hanging part happens while trying to do the initial connect to the nova conductor: https://github.com/openstack/nova/blo...

It seems to be unable to connect to it, so there might be some issues with rabbit, or firewall issues. From what I understood, the compute node is configured to use some sort of pro xy, which could also be the problem.

But the interesting part is, while trying to connect to the conductor, it has a timeout of 10 seconds (for the first 10 attempts), after which the timeout is set to None; but it never times out. This could also indicate some oslo.messaging issue, and might be worth looking into.
