Yes, I am not sure what went wrong in my first attempt, but know it is working 
as expected.

The file allocate_vfs is required for the subsequent reboots, but
during the deployment, the vfs are created by puppet-tripleo [1]. No
additional reboot required for creating VFs.

[openstack-dev] [TripleO] Configure SR-IOV VFs in tripleo

[Moshe Levi]

Hi  all,

While working on tripleo-ovs-hw-offload 
work, I encounter the following issue with SR-IVO.

I added -e ~/heat-templates/environments/neutron-sriov.yaml -e 
~/heat-templates/environments/host-config-and-reboot.yaml to the 
overcloud-deploy.sh.
The computes nodes are configure with the intel_iommu=on kernel option and the 
computes are reboot as expected,
than the tripleo::host::sriov will create /etc/sysconfig/allocate_vfs to 
configure the SR-IOV VF. It seem it requires additional reboot for the SR-IOV 
VFs to be created. Is that expected behavior? Am I doing something wrong?
