I also see the following in dmesg in the VM.
[0.095758] ACPI: PCI Root Bridge [PCI0] (domain [bus 00-ff])
[0.096006] acpi PNP0A03:00: ACPI _OSC support notification failed,
disabling PCIe ASPM
[0.096915] acpi PNP0A03:00: Unable to request _OSC control (_OSC
support mask: 0x08)

So, it could be the i40e driver then ? Because IIUC, VFs use a separate
driver. Just to rule out the possibility that there might be some driver
fixes that
could help with this, it might be a good idea to try a 3.19 or later upstream
kernel.
I tried with the latest DPDK release too

How is the device being assigned, pci-assign or vfio-pci? What QEMU
version? What host kernel version? Thanks,

Hi Alex,
Thanks for the response.
I tried both pci-assign and vfio-pci. The issue is seen in both cases.
i40e driver complains about data tx timeout.

You are assigning the PF right ? Does assigning VFs
