[PATCH 0/7] copy-in/copy-out: Capture errors from tar subprocess (RHBZ#1267032).

by Richard W.M. Jones

Commits 3c27f3d91e1566854747bbe844186783fc84f3a8 and 1b6f0daa9ae7fcc94e389232d0c397816cda973d added an internal API for running commands asynchronously. It is only used by the copy-in and copy-out APIs. Unfortunately this made the command code very complex: it was almost impossible to redirect stderr to a file, and there were a lot of long-range dependencies through the file. It was also buggy: it set up stderr of the child process pointing pipe, but never read from the pipe, so if the stderr output of the child process was sufficiently large then libguestfs would deadlock (possibly this can be triggered from a malicious filesystem too). This patch series first reverts these commits, then adds a simpler way to run a child process without waiting (modelled on popen()), allows stderr errors to be captured, then reimplements copy-in/copy-out using these new internal APIs. Note that the patch series breaks bisection, but I can't really think of a clearer way to reorganize it that would preserve bisection. Rich.

Build of supermin 5 on Ubuntu 14.04 LTS

by johnny＠johnnypumphandle.com

The latest Ubuntu distribution of libguestfs for Ubuntu 14.04 includes supermin 4. guestfish seems to gag. Apparently, I need supermin 5 to make things work. So I downloaded supermin_5.1.9.orig.tar.gz. I unzipped to a source folder /usr/local/src Then I attempted to build from source using ./configure I received this error: config.status: error: cannot find input file: `src/supermin-link.sh.in’ Sort of a noob at compiling from source, can anyone give me a workaround? here's the output stream .... design@BLFLIP:/usr/local/src$ ./configure checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for a thread-safe mkdir -p... /bin/mkdir -p checking for gawk... gawk checking whether make sets $(MAKE)... yes checking whether make supports nested variables... yes checking for style of include used by make...

ANNOUNCE: libguestfs & virt-v2v & virt-p2v RHEL 7.2 preview packages available

by Richard W.M. Jones

[The subject line isn't strictly correct, as virt-p2v packages aren't available right now, but will be shortly] If you are running RHEL 7.1 then you may be interested in trying out the newer RHEL 7.2 preview versions of: - libguestfs - virt-v2v (Technical Preview in RHEL 7.1, Supported in RHEL 7.2) - virt-p2v (Technical Preview in RHEL 7.2) To install the preview repository, copy the attached file into /etc/yum.repos.d/ Then use this command to update virt-v2v: yum install virt-v2v libguestfs-tools-c libguestfs-xfs To convert Windows guests you'll also need libguestfs-winsupport which is finally available in RHN (V2VWIN channel) or you can get it from http://people.redhat.com/~rjones/libguestfs-winsupport/ Please note these packages are *not* supported by Red Hat. If you find bugs, please file them using the link below: https://bugzilla.redhat.com/enter_bug.cgi?product=Red%20Hat%20Enterprise%... To downgrade back to the RHEL 7.1 supported packages, delete /etc/yum.repos.d/libguestfs-RHEL-7.2-preview.repo , uninstall libguestfs, then reinstall libguestfs from RHN. I have not tested these packages on CentOS 7.1, but they will probably work there too, and if they don't then let me know.

Change to how the Fedora package is tested

by Richard W.M. Jones

I added this commit last week: https://github.com/libguestfs/libguestfs/commit/f2540d68e4e62c8cf90ac501b... which allows installed libguestfs to be tested using the test suite included in the sources. Starting with Fedora Rawhide version 1.31.7-2, I'm going to disable the tests that happen during the Fedora (Koji) build, except for the basic kernel/qemu/libvirt/appliance sanity check. Instead, testing will now happen after the package has been built. Initially that'll just happen by me downloading the built package to my Rawhide test machine, and running the 'make installcheck' tests. But eventually I want to create some kind of infrastructure for this, triggered automatically when a Koji build completes. One upshot of this is that libguestfs will take a lot less time to build in Koji, with build times expected to go down from ~2 hours to ~20 minutes. If you want to run the tests yourself, then: (1) Download all the RPMs corresponding to the built package. (2) Install the binary RPMs. (3) Run 'rpmbuild -rc *.src.rpm' to unpack the source RPM, %prep and %build it. (4) In the builddir, run: $ make installcheck Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com virt-builder quickly builds VMs from scratch http://libguestfs.org/virt-builder.1.html

[PATCH] configure: Require OCaml if we need to run the generator.

by Richard W.M. Jones

When building from git, you need OCaml to compile the generator to build the generated files. Previously configure didn't detect that situation, resulting in failed builds. This commit causes the configure script to error out if the generated files are not present and OCaml is not installed. Note that you can still build without OCaml, if you get the generated files from somewhere else. The source tarballs distributed on the website contain the generated files. --- configure.ac | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/configure.ac b/configure.ac index 8ff6ce5..31cabc2 100644 --- a/configure.ac +++ b/configure.ac @@ -1117,6 +1117,15 @@ AM_CONDITIONAL([HAVE_OCAMLOPT], AM_CONDITIONAL([HAVE_OCAMLDOC], [test "x$OCAMLDOC" != "xno"]) +dnl OCaml is required if we need to run the generator. +AS_IF([test "x$OCAMLC" = "xno"],[ + AS_IF([! test -f $srcdir/src/guestfs_protocol.x],[ + AC_MSG_FAILURE([OCaml compiler is required to build from git. +If you don't have OCaml available, you should build from a +tarball from http://libguestfs.org/download]) + ]) +]) + AS_IF([test "x$OCAMLC" != "xno"],[ dnl Check for <caml/unixsupport.h> header. old_CPPFLAGS="$CPPFLAGS" -- 2.5.0

Wrong deficit calculation in virt-resize.

by Maxim Perevedentsev

Hello guys! I tried to shrink a partition when resizing an image using virt-resize. The numbers and result are weird. ================BEFORE================ ><fs> blockdev-getsize64 /dev/sdc 4294967296 ><fs> part-list /dev/sdc [0] = { part_num: 1 part_start: 65536 part_end: 2193555455 part_size: 2193489920 } [1] = { part_num: 2 part_start: 2193555456 part_end: 4294967295 part_size: 2101411840 } ><fs> list-filesystems /dev/sdc1: ext3 /dev/sdc2: ntfs So I have two parititons up to image end, and 64k block at the start. I wanted to shrink the last partition by 1MB (for test, yeah). I shrank the filesystem by 1MB but virt-resize refused to resize to 4095MB image requesting ~2MB more (the numbers you can see in log attached). So I had to shrink the filesystem by 4MB from original: ><fs> debug sh 'ntfsresize -f --info /dev/sdc2' ... Cluster size : 4096 bytes Current volume size: 2097213952 bytes (2098 MB) Current device size: 2101411840 bytes (2102 MB) ... ===============AFTER================== Now virt-resize succeeded. But the deficit miscalculation gave its result. ><fs> blockdev-getsize64 /dev/sda 4293918720 ><fs> part-list /dev/sda [0] = { part_num: 1 part_start: 65536 part_end: 2193555455 part_size: 2193489920 } [1] = { part_num: 2 part_start: 2193555456 part_end: 4291690495 part_size: 2098135040 } So I have 2228225 bytes after last partition empty. ><fs> debug sh 'ntfsresize -f --info /dev/sda2' Current volume size: 2098131456 bytes (2099 MB) Current device size: 2098135040 bytes (2099 MB) FS is ok, it fills the partition. ======================================== I looked at resize.ml and saw complex calculations of GPT header/end, alignment overhead and so on. I wondered whether virt-resize would create GPT on new image, but it didnt. Everything remained as before except empty space at the end. So the question is: is there a bug with deficit calculation or do I miss anything? -- Your sincerely, Maxim Perevedentsev
