Hi Friends,
I have some question regarding pci pass-though for bare metal host interface.
All following questions are for running vpp on bare metal ubuntu.
1. host interface won't showing up.
As i understand, when i start vpp, it can see all the host interface that are
in down state and not in host routing table. This is true if i run vpp in a
vagrant box ("show int" shows the down interface of vbox host). But this was
not happening when i ran vpp on bare metal ubuntu host. is there any additional
setting for bare metal linux?
2. Add host interface to vpp by using "create host-interface <name>"
The "create host-interface" command works fine with veth pair or tap interface.
For host physical nic interface, such as eth2, i can add it to vpp. It show up
as host-eth2. But it seems cannot passing traffic. Is it true the "create
host-interface " command does not suppose to work with physical interface?
3. pci passthrough.
With kernel 4.4.1, if i add pci number to dpdk white list in
/etc/vpp/startup.conf and bring up vpp, vpp can see the interface and pass
packets. But after upgrade kernel to 4.8, (ubuntu 16.4.02) even i added the
interface pci number to white list, vpp can not see the pass through interface
anymore.
Does vpp dpdk support kernel newer than 4.4.1?
Thanks a lot!
