Same here, and my pc doesn't have vt-d nor slat (second level addres tranlation); both required for Qubes 4 > It's not like I would not have the money to buy a 7700k, but I want to > avoid spending money if not necessary that is why I want to get a clear > picture... As far as i know, you can't just replace the cpu to get vt-d (IOMMU); also the chipset and the bios must have proper support so changing the cpu only might be a waste of money. There was a discussion about finding a notebook with proper support https://groups.google.com/forum/#!topic/qubes-users/Sz0Nuhi4N0o vt-d protect from dma (direct memory access) attacks. for a demo take a look at "inception" that works via firmware interface. i have personally tested against a windows xp and worked (from what i have read, newer os are protected against this *specific* attack). it protect you from bad/exploited dma devices like network card. net vm is used for both ethernet and wifi. for your use case (almost anyone use case) you don't need vt-d but we are starting to see succesful attacks against network interfaces, and thanks to the hard work of Qubes OS team and that genius person Joanna Rutkovska we have that extra protection for free. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
