libguestfs 1.6 will be the basis for RHEL 6.1. If you are using RHEL 6.0, thanks for supporting Red Hat, and if you want to try out the new version, then I have built some packages here: http://people.redhat.com/~rjones/rhel6.1-libguestfs-preview/ These are built on RHEL 6.0 and should install directly on top of RHEL 6.0. Some highlights: - Based on the upstream stable 1.6 branch. - Much better performance. - Many new features, see: http://libguestfs.org/RELEASE-NOTES.txt - virt-inspector is the RHEL 6.0 virt-inspector (deprecated upstream) - virt-inspector2 is the new upstream virt-inspector They should be completely source and binary compatible with the RHEL 6.0 packages, except for new features. So a program or script that you wrote against libguestfs 1.2.7 in RHEL 6.0 should work unchanged against these new packages. Note these packages are not official or supported by Red Hat. If you have any problems please post about it on the libguestfs mailing list: https://www.redhat.com/mailman/listinfo/libguestfs Rich. PS. The specifics are that we'll move to these versions in RHEL 6.1: - libguestfs 1.6.x, x >= 2, and backports https://bugzilla.redhat.com/show_bug.cgi?id=613593 - hivex 1.2.x, x >= 3 https://bugzilla.redhat.com/show_bug.cgi?id=642631 - febootstrap 2.10 https://bugzilla.redhat.com/show_bug.cgi?id=628849 -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones libguestfs lets you edit virtual machines.
