Virt Install is a command line tool built on top of libvirt that facilitates installation of virtual machines. It supports installation of fully-virtualized Xen guest machines for arbitrary operating systems and installation of Xen paravirtualized Fedora/RHEL operating systems. The tool takes care of fetching the guest kernels, creating file based disk images, and booting the guest operating system installer media. License: GNU General Public License (GPL) Changes:
When probing for OS distribution type, the tool now tests for the existence of files rather than fetching the entire file. RFC-compliant NFS URIs are accepted and converted where needed. When probing for Red Hat distribution variants, the "treeinfo" file is sought to determine initrd/kernel locations. User friendly errors are shown instead of stack traces, and bogus libvirt error messages are hidden from the console. A --noreboot flag was added to virt-install to prevent the automatic reboot at the end of install. The libvirt capabilities XML is used to determine the guest types supported by a hypervisor. A --force option was added to prevent any interactive prompting.
