Qubes uses VT-D and a Net VM to attempt to isolate buggy WiFi adapters from the rest of the Qubes system.
But this isolation still depends on Xen not having bugs... And we know that Xen has bugs, and will likely continue to have more going forward. So, instead of VT-D, why not just switch off DMA altogether..? In Debian, you can edit "/etc/hdparms.conf", and do stuff like this: /dev/hdc { dma = on } Why not just do this for WiFi and Ethernet chips in Qubes, and thus, not have to rely on Xen for isolation? -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
