Sounds like issues in the environment,
The PF (Physical function (external port)) connected to some switch, if so as Trunk?

Hi,
Some update on this, although I can launch the VM and see the VF inside it, I have 2 problems
1º Sometimes I don't get ip from dhcp when I launch a new instance.
Does the VF have the right VLAN tag?
2º I cannot ping the other hosts inside the tenant network using sr-iov nics. If I use ovs nics it works.
Are VLANs setup properly?
Joe
Anyone has experienced this issues?
Thanks,

I deployed openstack on DELL PowerEdge R620 installed with Centos 7.
SR-IOV is enabled in BIOS (both Virtualization Technology & SR-IOV).
Also, I added the needed kernel parameters and created virtual functions on 82599 Intel 10G NIC.
in nova.conf:
1. pci_passthrough_whitelist={"devname":"p2p1","physical_network":"sriovnet"}
2. scheduler_default_filters=RetryFilter,AvailabilityZoneFilter,RamFilter,ComputeFilter,ComputeCapabilitiesFilter,
ImagePropertiesFilter,CoreFilter,PciPassthroughFilter
Where did you supply the whitelist?
Also, after making the whitelist change did you check the nova-compute.log? It typically reports the PCI devices that can be used for instances.

Any idea what might be the problem here?
