The rest looks fine, but I'm not sure whether this is really needed so much that we should risk the test failing on some machines, especially in the future. Or actually even on my machine: $ touch ~/tmp/swap $ truncate ~/tmp/swap --size 128G $ fallocate -l 128G ~/tmp/swap # mkswap ~maxx/tmp/swap # swapon ~max/tmp/swap $ cd /to/qemu/build $ ./qemu-io -c 'reopen -o l2-cache-size=64G' test.qcow2 $ (Running the test itself is apparently a bad idea, because then for some reason Linux thinks I actually want to use the swap and everything slows down to a crawl) Max > + -c "reopen -o refcount-cache-size=256T" \ > + -c "reopen -o refcount-cache-size=64G" \ > + -c "reopen -o overlap-check=constant,overlap-check.template=all" \ > + -c "reopen -o overlap-check=blubb" \ > + -c "reopen -o overlap-check.template=blubb" \ > + "$TEST_IMG" | _filter_qemu_io > + [snip]
