You right, one can, but: * At least, this goes against the nature of Qubes. * You don't have any Internet connection there. * Creating only (and not importing anything) is a very important (and often unrealistic) assumption. So, you should not open any file you download. If there is some vulnerability in such software (well, Blender: https://developer.blender.org/T52924), you are actually potentially more affected than with traditional OS like Ubuntu: In Qubes, dom0 sometimes gets out of date (like Q3.2 being based on EOLed F23), so you don't receive any security update for software like Blender. That's not because ITL does not care about security, that's because Blender is not a a security-critical component like Xen or Linux kernel are. That's the cost of using Qubes in a way it was never intended. > If you have multiple GPU (i.e. integrated + NVidia), it is possible with Xen > to do GPU pass-through (Assign the NVidia GPU to a dedicated VM) however: > - It is far from trivial and only limited setups are known to work Right. > - The security of it is not as robust (I can't remember where I read that, I > think it was in the GPU Pass-through page of the Xen wiki) I guess one of potential reasons: Some people have succeeded only without stubdom, i.e., with QEMU running in dom0.
