 Managed to convert my Kerio Control 9.4 install to UEFI, but new kernel not new enough for Hyper-V [message #153590] |

Great that we finally have a newer kernel in Kerio Control. 
This helped me create a UEFI version of my Hyper-V Kerio Control guest for testing purposes. 
However saddened to find that not only does it not support SR-IOV in hyper-v, but also DDA (PCI passthrough) via hyper-V doesn't work.
It seems the kernel that was chosen may not have the supporting Hyper-V enlightenment to support SR-IOV for VF support (virtual function) and DDA (PCI passthrough).
On the other side, with KVM it all works fine, both SR-IOV VFs and physical ethernet nic device passthrough VFIO.
I hope the Kerio Control dev(s), add in the hyper-v SR-IOV and DDA (direct device assignment) support as part of the UEFI milestone, UEFI without the aforementioned will still keep Kerio severely restricted as far as performance is concerned.
Could someone pass the above notes onto the dev(s) please?
