[Xen-devel] Tracking guest pages modified by qemu-dm / backend
Consider an HVM domain with EPT. When qemu-dm, backend or any other
device model modifies DomU memory (like on a disk read or packet
received), how does Xen track the pages that have been modified? For
example, when an DomU is being migrated while IO is occurring.
Thanks,
AP
