Amazing as always ... particularly getting through the test suite during the build.

[REPOST] Differentiate 'distro' and 'distrofamily' in Sys::Guestfs::Lib

by Matthew Booth

I was slightly too quick off the marks with the first patch. This updated patch modifies all of virt-inspector's output types to take account of distrofamily.

Test failure w/ libguestfs-1.0.61 on RHEL5 -- needs virtio support in guest kernel?

See attachment for full logs.

Whither virt-inspector packaging?

by Charles Duffy

Looking at epel-testing, while libguestfs-* 1.0.57-2 is available, virt-inspector does not appear to be. http://cvs.fedoraproject.org/viewvc/rpms/libguestfs/EL-5/libguestfs.spec?... shows the virt-inspector bits commented out, and http://cvs.fedoraproject.org/viewvc/rpms/libguestfs/EL-5/libguestfs.spec?... doesn't appear to have an explanation. Wuzzup? :)

libguestfs in EPEL?

by Aron Griffis

Hi, The libguestfs homepage says that libguestfs and guestfish are available in EPEL, but I can't find any evidence of them there. I haven't made much use of EPEL so I might be missing something. Any suggestions? Thanks, Aron

Weird build bug in Koji / EL-5 (can anyone help?)

by Richard W.M. Jones

Compare this successful build of 1.0.60 in EPEL-5: http://kojipkgs.fedoraproject.org/packages/libguestfs/1.0.60/2.el5/data/l... with this unsuccessful build of 1.0.61, done ~24 hours later: http://koji.fedoraproject.org/koji/getfile?taskID=1477023&name=build.log The unsuccessful build fails with: /usr/lib/rpm/debugedit: canonicalization unexpectedly shrank by one character https://bugzilla.redhat.com/show_bug.cgi?id=304121 which is apparently caused by having ...//... (double slash) in a source file path while compiling. Indeed the case with the second build, but not with the first one. I've no idea what has changed between the two ... nothing significant as far as I can see. Anyone got any ideas?

[PATCH] Make Perl strings translatable

by Richard W.M. Jones

This patch makes Perl strings translatable. The Perl strings end up in the PO files as usual. It does not touch the embedded POD. Internationalizing the Perl strings was pleasantly simple. Just add: use Locale::TextDomain 'libguestfs'; at the top of any *.pl or *.pm file. Then for each string in the file that you want to be translatable you place TWO underscores before it: - die "virt-inspector: no YAML support\n" + die __"virt-inspector: no YAML support\n" unless exists $INC{"YAML/Any.pm"}; However this doesn't work if the string contains any $substitutions. In that case you have to use the __x (two underscores and x) operator: - die "guest image $_ does not exist or is not readable" + die __x("guest image {imagename} does not exist or is not readable", + imagename => $_) unless -r $_; The second case causes a note to be added to the PO file, so hopefully the translators will understand not to change the placeholders inside braces: +#: perl/blib/lib/Sys/Guestfs/Lib.pm:142 perl/lib/Sys/Guestfs/Lib.pm:142 +#, perl-brace-format +msgid "guest image {imagename} does not exist or is not readable" +msgstr "" The patch is otherwise fairly simple. I've changed po/POTFILES.in so that it is now generated automatically, and it includes the daemon code which we don't translate yet, but might consider doing in future. 'perl-libintl' is now a required module for virt-df / virt-inspector / virt-v2v (but not for the basic Perl bindings). This FAQ is useful to explain some of the reasons for the changes above: http://search.cpan.org/dist/libintl-perl/lib/Locale/libintlFAQ.pod Rich. -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones virt-df lists disk usage of guests without needing to install any software inside the virtual machine.

[PATCH] Fix: virt-inspector takes ages to run on RHEL 3 guests

by Richard W.M. Jones

Currently virt-inspector takes ages to run on RHEL 3 guests. I tracked this down to processing the old-style initrd images in these guests. These initrd images are compressed ext2 filesystems. 'cpio' tries to parse them as cpio files, and takes a very long time to fail (and spews out a lot of errors in the process). These two patches fix the problem: Firstly we introduce a new command 'zfile' for doing the 'file' operation inside compressed files. eg: guestfs_zfile (g, "gzip", "/boot/initrd.img") ==> "Linux rev 1.0 ext2 filesystem data" Second patch updates Sys::Guestfs::Lib to ignore such files.
