There is no particular event. The Linux balloon driver will at some point reach it when it's available. If you really want, I guess you can wait for it in a loop (observing /proc/meminfo or such). But as said in the initial response, it looks like a fundamentally wrong direction to take... > Also, how was the default initial 400 MB chosen? Initial memory is amount just necessary for VM to boot. There used to be a limitation in Linux that initial memory cannot be smaller than 1/10 of maxmem, but I think it's fixed nowadays. - -- Best Regards, Marek Marczykowski-Górecki Invisible Things Lab -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEEhrpukzGPukRmQqkK24/THMrX1ywFAmgwuJgACgkQ24/THMrX 1yxEMAf/Y12EbvsFEFMqVWNBMuQl9u4NiFSb7uA1OFoqqoi6UdeFW0iU6MdTb7OY lJ6yFX3ordYoWbK6YNCVus4NwIeMXqxqYI2fvvSztTZC1eOtqeQbh3YCxXaK4yNR 80hQYh6tOznK7n+O192B/Td/rlTyMNCVb+njCODyzKgcQUOtg14puqf/6/WxE3UM xwDlUqTHi0LvPh1FQA/GizXNfrBxwAst9K6mdXvs8nvpwMPwSQIds/5SXpDpX+OO oqByEIWuwpETH59lNXWnh2UmBRo27Tz3FAbhz17w8AbFPYCtfA8tyum61QEkMENB +abdsCW12A8VQ9jMGGNXR0cSiAqzQQ== =HQ3H -----END PGP SIGNATURE----- -- You received this message because you are subscribed to the Google Groups "qubes-devel" group.
