Quick questions: 1. Is there some official documentation comparing them? Only thing I found so far was https://mohamede.com/2019/02/07/pci-passthrough-type-pf-type-vf-and-type-pci/ 2. Am I correct to assume (I seem to do a lot of that; be afraid) that when nova starts populating the database entry for a given physical node (say a computer node or a ironic baremetal node) it looks through the pci list and decides what type of device (type-PCI, type-PF, or type-VF) it is? What is the criteria? 3. https://mohamede.com/2019/02/07/pci-passthrough-type-pf-type-vf-and-type-pci/ implies that nova sees the 3 different types, well, differently where it will try hard to virtualize type-PF and type-VF and really really wants me to setup sr-iov on them ( https://docs.openstack.org/nova/latest/admin/pci-passthrough.html seem to also want sr-iov) really . Is that correct? -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.openstack.org/pipermail/openstack-discuss/attachments/20190705/aa2e2bfb/attachment.html>
