Do NIC virtual functions support PXE boot?

I have a XCP (xenserver) host with a ConnectX-4 card. I have enabled VF on the NIC, and can pass them through to my VM’s.
My VM needs to PXE boot using the attached VF NIC, but booting fails with ‘no bootable device’.

Are VF’s supposed to support PXE booting or is this expected behavior?

Hello Martin,

Thank you for posting your inquiry on the NVIDIA Developer Forum - Infrastructure and Networking - Section.

Unfortunately this is not possible as the VF does not have access to the option ROM on the physical adapter. Expected behavior.

Thank you and regards,
