I'd say we have about 3 weeks to get things in. > > - Add dummy driver to hide/unbind passthrough device from host > > kernel This isn't needed; we currently don't assign the device to the guest if we find that a driver is already loaded. I intend to change it to failing guest start altogether in case we find a module already using a device. When a guest exits, we release all the structures and hence even unloading kvm is not needed to reclaim the device on the host side.
