问：当前performance面临的主要挑战是什么？ 答：VFIO makes it worse. When a physical device is passed through to a guest via VFIO, the kernel pins the physical pages behind the guest RAM mapping and programs the device’s IOMMU (Input/Output Memory Management Unit) to allow DMA to those specific physical addresses. Pinning means the kernel promises not to move or reclaim those pages, because hardware is going to write directly to them. If you mmap over the guest RAM region, the new mapping gets new physical pages, but the IOMMU is still programmed with the old physical addresses. The device keeps doing DMA to the old pages, which are no longer the guest’s memory. At best you get silent data corruption, at worst the device writes to pages that have been reclaimed and assigned to something else entirely.

In this dyst... utopia, nothing ever breaks because nothing is yours, nothing is repairable because nothing is physical, and nothing is private because everything runs elsewhere, on someone else's computer. The quiet lesson, felt when the network briefly stutters and the world freezes, is that keeping old hardware functional was never nostalgia or paranoia, but a small, persistent act of digital self-preservation; a refusal to accept that the future must be rented, permitted, and revocable at any instant.
