Hello Recently I'm using qemu-kvm on fedora-rawhide box with my own kernels (with many debug options) I've noticed that over the time my memory seems to disappear somewhere.
Here is my memory trace after boot and some time of work - thus memory should be populated. MemTotal: 2007460 kB MemFree: 618772 kB Buffers: 46044 kB Cached: 733156 kB SwapCached: 0 kB Active: 613384 kB Inactive: 541844 kB SwapTotal: 0 kB SwapFree: 0 kB Dirty: 148 kB Writeback: 0 kB AnonPages: 376152 kB Mapped: 67184 kB Slab: 80340 kB SReclaimable: 50284 kB SUnreclaim: 30056 kB PageTables: 27976 kB NFS_Unstable: 0 kB Bounce: 0 kB CommitLimit: 1003728 kB Committed_AS: 810968 kB VmallocTotal: 34359738367 kB VmallocUsed: 71244 kB VmallocChunk: 34359666419 kB 618772 + 46044 + 733156 + 148 + 376152 + 67184 + 80340 + 50284 + 30056 + 27976 = 2030112 2GB (though could be wrong - I could be wrong and adding something improperly) And this memory listing is when I work during the day with qemu-kvm do something like 30-50 qemu restarts. Then before I rebooted the machine I've killed nearly all running task (i.e no Xserver, most of services turned of) MemTotal: 2007416 kB MemFree: 652412 kB Buffers: 70000 kB Cached: 607144 kB SwapCached: 0 kB Active: 571464 kB Inactive: 709796 kB SwapTotal: 0 kB SwapFree: 0 kB Dirty: 0 kB Writeback: 0 kB AnonPages: 6408 kB Mapped: 4844 kB Slab: 52620 kB SReclaimable: 32752 kB SUnreclaim: 19868 kB PageTables: 1468 kB NFS_Unstable: 0 kB Bounce: 0 kB CommitLimit: 1003708 kB Committed_AS: 33988 kB VmallocTotal: 34359738367 kB VmallocUsed: 68152 kB VmallocChunk: 34359668731 kB I've have expected much more free memory here and I definitely do not see how this could combine 2GB of my memory: 652412 + 70000 + 607144 + 6408 + 4844 + 52620 + 32752 + 19868 + 1468 = 1447516 1.4GB so where is my 600MB piece of memory hiding ?
