Hi

I cannot get PTP hardware to work on a Virtual Function Ethernet Controller.
Here below you can see what I have tried with no luck.

How can I enable PTP hardware on Virtual function NIC, as from what I can read in the documentation this should work, but how?

As hypervisor I use VMware ESXi 6.7 (9484548)

Regards
Henning

On Ubuntu 18.04.1 (4.15.0-34-generic)
I am trying to get PTP to work on a X550 dual port, which has been setup so one port is SR-IOV (24 VF) and the other as Passthrough.

Hello,

As far as I know, PTP is not (and probably will not be) supported by VF driver.

Hi,

I can confirm that PTP is NOT supported on X550 VF device.
It works when one port is in pass-through mode as this is a PF device being mapped into the VM and not VF.

You can see in the ixgbevf driver that SIOCSHWTSTAMP ioctl is not handled.
There is no plan for PTP support for ixgbevf as for now.

Thanks, Tim

Hi Tim

Thanks for the answer, but that also means that hardware PTP in a virtual machine cannot be made.
There are some finance regulation (high speed trading) here in Europe which need hardware PTP to be precise enough.

So this need to be made in a physical server. Pass-through is not the way to go as you cannot vMotion the VM, so no benefit

Regards
Henning

Some silly questions...

What regs require PTP?

If an extreme level of time accuracy is required, wouldn?t that preclude any concept of vMotion?

Why wouldn?t you run clock synchronization on the host and pass the host clock through to the guest?

Hi Tim

Thanks for the answer, but that also means that hardware PTP in a virtual machine cannot be made.
There are some finance regulation (high speed trading) here in Europe which need hardware PTP to be precise enough.

So this need to be made in a physical server. Pass-through is not the way to go as you cannot vMotion the VM, so no benefit

Emne: RE: X550 VF do not support PTP

Hi,

I can confirm that PTP is NOT supported on X550 VF device.
It works when one port is in pass-through mode as this is a PF device being mapped into the VM and not VF.

You can see in the ixgbevf driver that SIOCSHWTSTAMP ioctl is not handled.
There is no plan for PTP support for ixgbevf as for now.

Thanks, Tim

Hello,

As far as I know, PTP is not (and probably will not be) supported by VF driver.

Hi

I cannot get PTP hardware to work on a Virtual Function Ethernet Controller.
Here below you can see what I have tried with no luck.

How can I enable PTP hardware on Virtual function NIC, as from what I can read in the documentation this should work, but how?

As hypervisor I use VMware ESXi 6.7 (9484548)

Regards
Henning

On Ubuntu 18.04.1 (4.15.0-34-generic)
I am trying to get PTP to work on a X550 dual port, which has been setup so one port is SR-IOV (24 VF) and the other as Passthrough.

04:00.0 Ethernet controller: Intel Corporation Ethernet Controller 10G X550T (rev 01)
0b:00.0 Ethernet controller: Intel Corporation X550 Virtual Function
13:00.0 Ethernet controller: Intel Corporation X550 Virtual Function

To be sure that the drive support PTP I downloaded the newest driver
ixgbevf-4.3.5.tar.gz
sudo make CFLAGS_EXTRA="-DIXGBE_PTP" install (The documentation says this options has to be set)

* [Intel-wired-lan] X550 VF do not support PTP

That said, I seriously doubt that you can meet a 100us sla in a vm no matter what you do. Even if the clock is stable enough for normal operation, almost anything you do management wise will violate the sla. vMotion is absolutely going to violate it.

FWIW, ptp isn?t a requirement. You can (easily) meet the 100us traceability requirement with NTP sourced from an on premise gps system. A couple of LeoNTP units and chronyd with hardware timestamps on a 1 second poll interval can achieve this easily. 

Best,
Denny
