What about extending the ballooning driver to export the page database to the hypervisor so it can just see what pages are allocated or not? Ksm can consult that when considering pages to steal. You'd also want some way for the kernel to know when a page was stolen and has now been returned, so it can skip zeroing it since that was already done by the hypervisor. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBAgAGBQJRIqRuAAoJEJrBOlT6nu75edUIANUVWiZDTvbaGBzx3P5StjIF D8AYiMYdy6H1TWjQ23Su++NNcP/8cuLzur3UGokD/z37w/qv6jwfFscXTCh6BGf4 EeCdMyfP6rw69ea8cknvQhqf3G/XgGlOpBTRstP6WykV8kqsnPYijcEJh7yDv7Ej IDZg9xSQdgcsTayAbI0g8vdCeFIneWYl71Pq1jVDeaRQ5QF9NJ4l2qFTbwzWtgco HGSLhmoxEQ2f4kRQUs5pGAWq/KjqNiUbNtRs0N023EcGy3skCSurtRDADdDk8XxT dIRFYqDvpbN9q5Y+3U17zWCgwrRj/ChL+6hDr6XnSbLEJZH4KUZJlthrF5HyrVM= =Jk4V -----END PGP SIGNATURE----- -- ubuntu-devel mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel
