[Openstack] Kolla Deployment QEMU instead of KVM

 OK! I see...

 Unfortunately I cannot spawn an image and the error in dashboard is :
 Error: Failed to perform requested operation on instance "test", the 
 instance has an error status: Please try again later [Error: No valid 
 host was found. There are not enough hosts available.].

 If I login to the nova-compute docker container as : docker exec -u 0 
 -it nova_compute bash

 and check the logs at /var/log/kolla/nova/nova-compute.log I see this:

 2017-02-28 22:40:20.351 7 ERROR nova.compute.manager [instance: 
 dec9d97a-3c27-42cb-ad75-f45dc2e58154] libvirtError: internal error: 
 process exited while connecting to monitor: Could not access KVM kernel 
 module: Permission denied
 2017-02-28 22:40:20.351 7 ERROR nova.compute.manager [instance: 
 dec9d97a-3c27-42cb-ad75-f45dc2e58154] failed to initialize KVM: 
 Permission denied


 On the physical host I have disabled SELINUX but without any further 
 impact.


 Any ideas?


 Best,

 G.
