[PATCH] sparsify: Fix test-virt-sparsify-in-place-fstrim-unsupported.sh

by Richard W.M. Jones

Since Linux commit f663b5b38fff trimming vfat is now supported by Linux. This broke the test which assumed it was not supported. Use another filesystem (minix) which does not support trimming instead. Thanks: Daniel P.

Tests and trimming vfat

by Richard W.M. Jones

Here's a fun one: + guestfish -N test-virt-sparsify-in-place-fstrim-unsupported.img=fs:vfat exit + virt-sparsify --in-place test-virt-sparsify-in-place-fstrim-unsupported.img + tee test-virt-sparsify-in-place-fstrim-unsupported.log [ 2.4] Trimming /dev/sda1 [ 7.5] Sparsify in-place operation completed with no errors + grep 'warning:.*fstrim' test-virt-sparsify-in-place-fstrim-unsupported.log FAIL test-virt-sparsify-in-place-fstrim-unsupported.sh (exit status: 1) We expect (for the purposes of the regression test) that vfat filesystems cannot be trimmed. It turns out that fstrim for vfat has now been implemented in Linux (commit f663b5b38fff) :-) Thanks Wentao Wang (this is actually great for virt-v2v). So we need to find another filesystem which doesn't support fstrim. Or maybe just delete this regression test. Thoughts?

[PATCH 0/7] RFC: switch v2v to ocaml-libvirt

by Pino Toscano

Hi, this is a mostly done attempt to switch to ocaml-libvirt, embedding the latest version of it from git. This way, it is possible to improve the way v2v connects to libvirt for both input, and output modules, and interacts with libvirt (e.g. no more virsh calls needed in virt-v2v). As side effect, virt-v2v now requires libvirt, as keeping it optional would create too much burden. I could not test all the libvirt input modes (like VDDK, and Xen), but VMware and libvirtxml work fine as before. Thanks, Pino Toscano (7): v2v: require libvirt common: Bundle the ocaml-libvirt library for use by virt-v2v v2v: switch to ocaml-libvirt v2v: -o libvirt: use a Lazy for the connection v2v: -o libvirt: switch away from virsh v2v: test-harness: stop using the external ocaml-libvirt build: stop looking for ocaml-libvirt .gitignore | 2 + Makefile.am | 5 +- common/mllibvirt/Makefile.am | 102 ++ common/mllibvirt/generator.pl | 890 ++++++++++++++ common/mllibvirt/libvirt.README | 9 + common/mllibvirt/libvirt.ml | 1624 +++++++++++++++++++++++++ common/mllibvirt/libvirt.mli | 1537 +++++++++++++++++++++++ common/mllibvirt/libvirt_c_epilogue.c | 420 +++++++ common/mllibvirt/libvirt_c_oneoffs.c | 1550 +++++++++++++++++++++++ common/mllibvirt/libvirt_c_prologue.c | 129 ++ configure.ac | 1 + docs/C_SOURCE_FILES | 1 - m4/guestfs-ocaml.m4 | 4 - po/POTFILES | 1 - v2v/Makefile.am | 26 +- v2v/copy_to_local.ml | 7 +- v2v/dummy.c | 2 + v2v/input_libvirt.ml | 20 +- v2v/input_libvirt_other.ml | 27 +- v2v/input_libvirt_other.mli | 5 +- v2v/input_libvirt_vcenter_https.ml | 13 +- v2v/input_libvirt_vcenter_https.mli | 2 +- v2v/input_libvirt_vddk.ml | 21 +- v2v/input_libvirt_vddk.mli | 4 +- v2v/input_libvirt_xen_ssh.ml | 13 +- v2v/input_libvirt_xen_ssh.mli | 2 +- v2v/input_libvirtxml.ml | 3 +- v2v/libvirt_utils-c.c | 539 -------- v2v/libvirt_utils.ml | 95 +- v2v/libvirt_utils.mli | 51 +- v2v/output_libvirt.ml | 56 +- v2v/parse_libvirt_xml.ml | 14 +- v2v/parse_libvirt_xml.mli | 11 +- v2v/test-harness/Makefile.am | 5 +- v2v/v2v.ml | 12 +- 35 files changed, 6500 insertions(+), 703 deletions(-) create mode 100644 common/mllibvirt/Makefile.am create mode 100755 common/mllibvirt/generator.pl create mode 100644 common/mllibvirt/libvirt.README create mode 100644 common/mllibvirt/libvirt.ml create mode 100644 common/mllibvirt/libvirt.mli create mode 100644 common/mllibvirt/libvirt_c_epilogue.c create mode 100644 common/mllibvirt/libvirt_c_oneoffs.c create mode 100644 common/mllibvirt/libvirt_c_prologue.c create mode 100644 v2v/dummy.c delete mode 100644 v2v/libvirt_utils-c.c -- 2.17.1

by Richard W.M. Jones

v1 was here: https://www.redhat.com/archives/libguestfs/2018-August/thread.html#00287 v2: - The -oa option now gives an error; apparently Cinder cannot generally control sparse/preallocated behaviour, although certain Cinder backends can. - The -os option maps to Cinder volume type; suggested by Matt Booth. - Add a simple test.
