> what support does it need? Intel Virtualization Technology for Directed I/O" (VT-d). VT-d is a virtualized IOMMU, so by using HYP type 1 there should be a VT-d driver supporting VT-d HW extension (?), as my best understanding is
The practical implications are Graphics and Network Connectivity in Guests. DMA Remapping is the feature of VT-d. Good net pointer to read: https://unix.stackexchange.com/questions/34428/do- virtualbox-or-vmware-use-the-intel-vt-d-feature > Is anybody working on this? Don't think so... If anything is done, I guess, it is done by simplistic implementation of the feature called: pass-through (so guest by its own drivers is using directly platform devices' HW bypassing HYP1, my best guess).
