Happily I finally found some time to look into this and the news is good... I took the latest XenServer driver installer and ran it inside a Windows 10 VM on one of my upstream test rigs and it ran to completion (managing the necessary reboots to displace emulated devices) in non-interactive mode with no problems, so this could definitely be used in osstest to get PV drivers into Windows VMs as longs as osstest can handle waiting for the intaller's "I'm finished" flag to appear in xenstore (attr/PVAddons/Installed = 1).
