Generally, from configuration POV, PVHv2 is very similar to PV[*], but there are multiple architectural differences. The current plan is to release Qubes 4.0 and then resume work on PVHv2 (which may turn out to be very minimal needed) and have it in Qubes 4.1. This may mean it will also work (at least partially) in Qubes 4.0, if we're lucky ;) [*] basically setting "device_model_version=none" - -- Best Regards, Marek Marczykowski-Górecki Invisible Things Lab A: Because it messes up the order in which people normally read text.
