I doubt it will be easy. In theory, you casn patch it and get something between Qubes 3 and Qubes 4, but I am not sure about its complexity.
Qubes switches from PVs to HVMs in Qubes 4. This unfortunately adds some hardware requirements. While most today CPUs have VT-x and EPT (or AMD equivalents), missing VT-d might be the issue. The VT-d is needed for assigning a PCI device to a VM, which is needed for sys-net and sys-usb VMs. With older Qubes, there is some hack used in absence of VT-d. The hack has, however, tweo drawbacks: * It exposes all the memory via DMA. * It works with PVs only. Maybe you can be lucky when trying to use PVs just for sys-net and sys-usb and other parts will work out of box. I don't know the exact way to achieve it. And I doubt there will be a complete howto for that. Regards, Vít Šesták 'v6ak' -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
