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

Hi  all,

While working on tripleo-ovs-hw-offload<https://review.openstack.org/502313> 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?
