Open Stack

I don't think that this problem is related to AppArmor.

It is happening again but, it is random, on a host without AppArmor installed...

The logs shows:


nova-compute.log:

libvirtd.log:

2015-10-21 15:07:14.578+0000: 2805: error : virNetDevTapCreate:290 :
Unable to create tap device tapab04671d-75: Device or resource busy
---

I'm trying to launch the following Stack:

https://github.com/sandvine/os-ansible-deployment-lite/blob/liberty/misc/os-heat-templates/sandvine-stack-0.1-cs-1.yaml

It failed (CREATE_FAILED), then, I tried it again, and it works
(CREATE_COMPLETE)!     :-/

This never happened with Kilo (very same Heat Template)...

It seems that, the first time that of launch, after uploading a qcow2,
it fails, then, the second time, it works...

Am I missing something here?

Thanks!
Thiago
