If you are running RHEL 7 betas or the RHEL 7 Release Candidate[1], or (in the near future) when RHEL 7 GA or CentOS 7.0 is released, then you may be interested in previewing the libguestfs packages for RHEL 7.1. We intend to rebase[2] libguestfs to 1.26 or 1.28 in RHEL 7.1. This will deliver many new features[3] including virt-builder, virt-customize, and the new virt-p2v/virt-v2v, while retaining complete compatibility with RHEL 7 GA. To install the preview repository, run the following command as root: cat >/etc/yum.repos.d/libguestfs-RHEL-7.1-preview.repo <<EOF [libguestfs-RHEL-7.1-preview] name=libguestfs RHEL 7.1 preview - x86_64 baseurl=http://people.redhat.com/~rjones/libguestfs-RHEL-7.1-preview/ enabled=1 gpgcheck=0 EOF Then: yum install libguestfs-tools Running 'libguestfs-test-tool' after this is a good idea, since it will tell you if the new version of libguestfs is working or not. If you want to try a more thorough set of tests, then see: http://libguestfs.org/guestfs-testing.1.html These packages are *not* supported by Red Hat. To go back to the supported packages, uninstall libguestfs, delete the file /etc/yum.repos.d/libguestfs-RHEL-7.1-preview.repo and install libguestfs again.
