Hi,

(2014/10/22 22:48), O'driscoll, Tim wrote:

> PCI Hot Plug: When you migrate a VM, you need hot plug support as the new VF on the new hardware you are running on post-migration needs to be initialized. With an emulated NIC migration is seamless as all configuration for the NIC is within the RAM of the VM and the hypervisor. With a VF you have actual hardware in the picture which needs to be set up properly.

I have patch series for that feature.
The patches add feature that DPDK apps can attach and detach physical
NIC ports and virtual device ports at runtime.
Also I have patches for testpmd to attach and detach ports dynamically.

For example, after patching, we can type following commands.
testpmd> port attach p 0000:02:00.0
testpmd> port attach v eth_pcap0,iface=eth0
testpmd> port detach p <detaching port_id>
testpmd> port detach v <detaching port_id>
(These are just RFC.)

Now I am collecting up patches to submit to dpdk.org. So I can send RFC
patches soon. Hopefully next week.

Thanks,
Tetsuya
