Please keep qemu-devel@nongnu.org CCed so others can contribute to the discussion. QEMU only deals with virtual memory when simulating an MMU (for ARM-on-x86 system translation). The device model usually operates on physical RAM or bus addresses. Stefano or Anthony can explain the qemu-dm specifics. It's still not clear to me what you're trying to observe - qemu-dm is not where I'd try to observe domain memory under Xen but it's the right place to observe emulated devices. Stefan
