There every wiki version can be compared with every wiki version and it will show exactly what was changed (added text, removed text, edited text) as well as show which wiki account made the edit if any. Otherwise
Sometimes I make edits when I’m too lazy to sign in, that’s why I assumed that’s what happened here. Thought it was coming from a trusted source.There’s no excuse for this lapse though and it’s the first time I encounter this.
Keep or discard? Can this have security consequences?
No only VT-x. Only hardware passthrough like GPUs woudl need VT-d but this is unrecommneded for security reasons and virtio devices should be used whenever possible if high performance is needed.
Not a hard requirement, not enforced. As correctly quoted…
…“required for effective isolation of network VMs”. Hardware without IOMMU are still reported to run Qubes on the same website but these then don’t have “effective isolation of network VMs”.
Well, then if not having IOMMU, then don’t use Qubes because it then doesn’t have “effective isolation of network VMs”? No, that would also be wrong. No operating system would provide “effective isolation of network VMs” without IOMMU. So no Qubes specific disadvantage here either.
So yeah. Computer security. Complicated. Even a short and correct statement actually describing a feature/advantage (“with IOMMU you get effective isolation of network VMs”) with “required for effective isolation of network VMs” can be misunderstood in two negative ways which are false.
Please do as you see fit.
If the older one doesn’t come up anymore, it could even be completely removed.
If users using older systems still run into it, might be useful to keep the error message inside the text.
I stand corrected though in my defense, the last time I checked years ago when 4.X debuted, they implied that they won’t make exceptions for Vt-d-less hardware and reading the hardware reqs seems to imply this by listing this feature as a min req.
