[Libguestfs] Making the tests faster

Currently 'make check' takes 23 minutes (at least) to run on my shiny new laptop. I'd like to make this faster because I spend a lot of time waiting for them to finish, but first here's an analysis of time spent now. Build the test guests: [only happens once, as long as you don't make clean]: tests/guests: 72 seconds Test gnulib: gnulib: 13 seconds Testing the API (about 12 minutes in total): tests/qemu: 13 seconds tests/c-api: 277 tests/protocol: 16 tests/disks: 90 tests/mountable: 20 tests/lvm: 10 tests/luks: 53 tests/md: 88 tests/selinux: 13 tests/ntfsclone: 10 tests/rsync: 10 tests/disk-labels: 4 tests/hotplug: 20 tests/nbd: 15 tests/syslinux: 10 tests/regressions: 62 [tests/btrfs skipped by local configuration] [tests/mount-local skipped by local configuration] Testing guestfish and bindings (about 6 minutes): fish: 70 seconds perl: 15 ocaml: 190 python: 5 ruby: 10 java: 5 haskell: 4 php: 7 erlang: 10 lua: 29 gobject: 10 Testing tools (about 5 minutes): align: 12 seconds cat: 40 df: 16 edit: 27 format: 17 inspector: 19 rescue: 4 resize: 29 sparsify: 69 sysprep: 29 tools: 17 fuse: 20 Test environment: libguestfs 1.21.33 libvirt 1.0.3 backend qemu 1.0.4 Fedora 19 Intel Core i7-3520M Hard disk (not SSD) Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones virt-df lists disk usage of guests without needing to install any software inside the virtual machine.
