[PATCH] m4: Add java search path for Gentoo

by Martin Kletzander

In Gentoo the java alternatives are managed using jva-config (or eselect java), but because the selection is treated as a configuration the symlink to the current jvm selected is stored in /etc, particularly in the symlink /etc/java-config-2/current-system-vm which works such as /usr/lib/jvm/default.

[PATCH] v2v: create an empty windows.vmdk in case of disabled appliance

by Pino Toscano

In case the appliance is disabled at configure, then all the phony guests will not be built during the 'make check' time. Since the tests already handle an empty windows.vmdk fine (in case ntfs-3g is not available), then just create it empty in this case.

[PATCH 0/2] v2v: uninstall the VMware Tools from Windows guests

by Pino Toscano

It seems newer versions of VMware Tools for Windows can be uninstalled also when the guest does not run on VMware anymore. Hence, attempt to uninstall them during a conversion, reusing the same code already used to uninstall Parallel Tools. This was tested with the following Windows guests: - Windows 2008r2 - Windows 2012r2 - Windows 2016 - Windows 7 - Windows 8 - Windows 10 Pino Toscano (2): v2v: windows: factor uninstall commands search v2v: windows: uninstall VMware Tools v2v/convert_windows.ml | 62 ++++++++++++++++++++++++++++++++++-------- 1 file changed, 51 insertions(+), 11 deletions(-) -- 2.17.2

[PATCH] test-data: Allow tests to be run when Btrfs is not available.

by Richard W.M. Jones

Create the fedora-btrfs.img as an empty file. The only place this is used explicitly is tests/mountable/ test-mountable-inspect.sh, but that test already skips if !btrfs. Also this is used via guests-all-good.xml, but the script that creates this XML skips the file if it has zero size. --- test-data/phony-guests/make-fedora-img.pl | 21 +++++++++++++++++++-- 1 file changed, 19 insertions(+), 2 deletions(-) diff --git a/test-data/phony-guests/make-fedora-img.pl b/test-data/phony-guests/make-fedora-img.pl index c665f0d19..739a229da 100755 --- a/test-data/phony-guests/make-fedora-img.pl +++ b/test-data/phony-guests/make-fedora-img.pl @@ -39,8 +39,15 @@ my @PARTITIONS = ( # 32k blank space ); -my @images; +# Test features. my $g = Sys::Guestfs->new (); +$g->add_drive ("/dev/null"); +$g->launch (); +my $btrfs_available = $g->feature_available (["btrfs"]); +$g->close (); + +my @images; +$g = Sys::Guestfs->new (); my $bootdev; @@ -122,7 +129,17 @@ EOF init_lvm_root ('/dev/md/rootdev'); } -elsif ($ENV{LAYOUT} eq 'btrfs') { +elsif ($ENV{LAYOUT} eq 'btrfs' && !$btrfs_available) { + # Btrfs not available, create an empty image. + push (@images, "fedora-btrfs.img"); + + unlink ("fedora-btrfs.img"); + open (my $img, '>', "fedora-btrfs.img"); + close ($img) or die; + exit 0; +} + +elsif ($ENV{LAYOUT} eq 'btrfs' && $btrfs_available) { push (@images, "fedora-btrfs.img-t"); open (my $fstab, '>', "fedora.fstab") or die; -- 2.19.0.rc0

[PATCH nbdkit v3 0/4] build: Replace ./nbdkit with a C program.

by Richard W.M. Jones

v1 was here: https://www.redhat.com/archives/libguestfs/2018-November/msg00147.html v2 was here: https://www.redhat.com/archives/libguestfs/2018-November/msg00152.html v3: - Use optarg != NULL as a sentinel for has_arg. - Moved some variable decls into the inner loop. - Make nbdkit wrapper depend on config.status, so if srcdir or builddir changes then we rebuild the wrapper. It probably does so anyway because <config.h> will change, but let's be safe. - Document NBDKIT_VALGRIND=1 and NBDKIT_GDB=1. - Add two extra patches which fix existing uses of NBDKIT_VALGRIND. - Retested (make check && make check-valgrind).

[PATCH nbdkit v2 0/2] build: Replace ./nbdkit with a C program.

by Richard W.M. Jones

v1 was here: https://www.redhat.com/archives/libguestfs/2018-November/msg00147.html v2: - Use stdbool for booleans. - Use __attribute__((format(printf))). - Don't abort on invalid options, exit with failure instead. - Preserve long/short option choices in the output. - Add '=' in long option output, ie. always use --longopt=arg. - Add "--" parameter (unconditionally) before non-options. - Fix comments that referred to "alphanumeric" plugin and filter names. - Retested.

[PATCH 0/2] build: Replace ./nbdkit with a C program.

by Richard W.M. Jones

This patch series solves the FreeBSD shebang problem in a completely different way, and a few other things besides. I propose that we replace ./nbdkit with a C program. The C program is a straightforward translation of the shell script. Some advantages of this approach are: - We can parse options in exactly the same way as the real program. - Use the more accurate ‘is_short_name’ test for unadorned plugin/filter names on the command line. - Fixes the FreeBSD problem with shebangs caused because FreeBSD refuses the use a shell script as a shebang path. - No longer need to maintain that troublesome shell script. I have verified that this does indeed fix the FreeBSD shebang problem (but didn't test on Haiku). It also passes 'make check' and 'make check-valgrind' on Linux. Rich.

[PATCH v5 0/3] Install QEMU-GA from oVirt guest tools ISO on Linux

by Tomáš Golembiovský

changes in v5: - simplified expression in copy_drivers - new commit fixing path constructions - indentation fixes changes in v4: - fix call to install_local changes in v2: - moved copy_drivers above copy_files - renamed copy_files to copy_from_virtio_win - renamed install to install_local - use rpm instead of yum This installs packages with QEMU Guest Agent when converting Linux machine. The packages should be available on guest tools ISO. The patches work "as-is" but probably deserve some more attention: - it is "abusing" Winows_virtio code but renaming/refactoring everything to remove "windows" from the name and use "guest tools" seems like a lot of unnecesary work - support for Debian is missing I don't know how to install the package only when all it's dependencies are already installed. dpkg cannot be used to check that (simulate the install). And attempting to install the package will leave it half-installed (dpkg cannot roll-back).
