You can use the new version without installing it. However you would need to be able to install a compiler and other dependencies, which may not be possible on a production system. > Also the new version is not available in repo. > > > > Im getting antother problem : > > while running these commands im getting error : > guestfish -- add /dev/null : config -set > drive.hd0.file=rbd:ssd-clonetest-rule5/ubuntu-12.04--1.raw.img : run : > inspect-os > /dev/ubuntu-1204-vg/root > [root@EQkvm0101 ~]# guestfish -- add /dev/null : config -set > drive.hd0.file=rbd:ssd-clonetest-rule5/ubuntu-12.04--1.raw.img : > inspect-get-distro /dev/ubuntu-1204-vg/root > libguestfs: error: no inspection data: call guestfs_inspect_os first You have to call inspect-os, and pass the returned value back to inspect-get-distro. This is (to say the least) awkward in guestfish, but much easier if you use a real programming language (libguestfs has many language bindings, see http://libguestfs.org). Also you are missing a call to 'run'. Here's how you could do it in Perl: ------------------------------------------------------------ #!/usr/bin/perl -w use strict; use Sys::Guestfs; my $g = Sys::Guestfs->new (); $g->add_drive_opts ("/dev/null", readonly => 1); # RHEL 6 hack for adding Ceph drives: $g->config ("-set", "drive.hd0.file=rbd:ssd-clonetest-rule5/ubuntu-12.04--1.raw.img"); $g->launch (); my @roots = $g->inspect_os (); if (@roots == 0) { die "no operating systems found"; } my $root = $roots[0]; my $distro = $g->inspect_get_distro ($root); print "distro = $distro\n"; ------------------------------------------------------------ Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming blog: http://rwmj.wordpress.com Fedora now supports 80 OCaml packages (the OPEN alternative to F#)
