fallocate() is needed for snapshotting. If it isn’t whitelisted $ qemu-img create -f qcow2 x.qcow 1G Formatting 'x.qcow', fmt=qcow2 size=1073741824 encryption=off cluster_size=65536 lazy_refcounts=off $ qemu-kvm -display none -monitor stdio -sandbox on x.qcow QEMU 2.1.50 monitor - type 'help' for more information (qemu) savevm foo (qemu) loadvm foo will fail, as will subsequent savevm commands on the same image. fadvise64(), inotify_init1(), inotify_add_watch() are needed by the SDL display. Without the whitelist entries, qemu-kvm -sandbox on fails immediately. In my tests fadvise64() is called 50--51 times per VM run. That number seems independent of the duration of the run. fallocate(), inotify_init1(), inotify_add_watch() are called once each. Accordingly, they are added to the whitelist at a very low priority.
