Contrail Openstack: Nested Virtualization

‎07-06-2016 11:48 PM



In our lab setup we setup contrail and openstack in an ESXi and Virtualbox environments.


The installation went through fine, however when trying to spawn a new instance from Openstack, we were receiving the following error "Can't create instance, no valid host was found". 


The compute logs logs under /var/log/nova# more nova-compute.log  showed:

"Error: internal error: no supported architecture for os type 'hvm'"


We had to edit the following file: /etc/nova/nova-compute.conf  and change the virt_type from kvm to qemu.

root@Openstack-Contrail:/etc/nova# cat nova-compute.conf


Thereafter we had to restart the nova-compute service: # service nova-compute restart


After which we were able to successfully spawn the new instance.


Best Regards,
