其次,Complexity for the orchestrator. With eager copy, restore is atomic in the sense that the VM either starts with all its memory or it does not. With on-demand, the VM starts immediately but page faults can fail because of a disk error or a corrupted snapshot. The failure mode shifts from “restore fails” to “guest crashes mid-execution on a bad page.” The orchestrator needs to handle this differently.

此外,Parting thoughtsUserfaultfd was not designed solely for VM snapshot restore. AFAIK, post-copy live migration was one of the original motivations, where a VM starts on the destination host before all its memory has been transferred and missing pages are faulted in from the source over the network (QEMU has supported this since 2.6). CRIU uses it for lazy process restore, serving checkpoint pages on demand instead of reading them all upfront. And distributed shared memory systems use it to fetch pages from remote nodes on access, presenting a flat address space backed by network storage.
