Thank you for the information. This is unfortunate and does not allow
us to use vhost-user as it is on Windows.
fwiw, Windows has other mechanisms to share resources between processes.
To share/pass sockets, you can use WSADuplicateSocket. For shared
memory and other resources, DuplicateHandle API.
Cool, thanks for sharing that. So it could be done, but I think we need
to extend the vhost-user protocol to work with Windows.
Thanks,
Stefano
(you can also share other things like D3D textures etc. those
mechanisms are used to enable -display dbus on Windows efficiently)
