第三,The guest executes a memory access and the guest kernel’s page tables translate the guest virtual address to a Guest Physical Address. The CPU then walks the EPT/NPT to translate the Guest Physical Address to a Host Physical Address, but the page has no physical backing because we skipped the eager copy. So the CPU triggers a VM exit. KVM handles the VM exit and converts it to a host page fault on the corresponding address in the VMM’s mmap region. The host kernel sees the fault, checks the userfaultfd registration, suspends the vCPU thread, and writes a fault message to the uffd fd. The handler thread wakes up, computes the offset into the snapshot file, reads the page data, and calls UFFDIO_COPY. The kernel populates the page within the existing mapping and wakes the vCPU thread. The vCPU re-enters guest mode, the EPT/NPT walk succeeds this time, and the guest instruction completes.
