Hi,

I have a problem when reading the wiki below, which is based on the latest SRIOV design.
https://wiki.openstack.org/wiki/PCI_passthrough_SRIOV_support#API_interface

My problem is about the "PCI SRIOV with tagged flavor" part.
In "pci_information =  { { 'device_id': "8086", 'vendor_id': "000[1-2]" }, { 'e.physical_network': 'X' } }" , I'm confused what is the "e.physical_network", if it means a network resource, why we need to filter the assignable nics by a network resource?
Can you please tell me more about the "physical_network" here, thanks a lot.
In "{'e.physical_netowrk':'X', 'count': 1 }", I think the "count" means the count of virtual nics a SRIOV nic can support, is that right?

In the last step while booting a vm with a virtual nic, the command is "nova boot  mytest  --flavor m1.tiny  --image=cirros-0.3.1-x86_64-uec  --nic  net-id=network_X  pci_flavor= '1:phyX_NIC;'".
I noticed that, "pci_flavor" is prompted while there already has the m1.tiny flavor, will the "pci_flavor" be separated from the normal flavor in the next step?

Thanks
