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?
this it for the Neutron SRIOV, a physical netowrk is a attribute added
to a pci device. if you want allocated a nic from pci, you must ensure
we get a PCI device which does connect to the correct physical network
as same as Neutron defined.
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?**
yes.
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?
yes. but not mean the pci_flavor is separated from normal flavor, the
flavor is the original alias with api support. we rename to pci_flavor
because it's just for pci and the flaovr things much more OS style.
hope help you.
Yongli He
Thanks
