+Libguestfs is a library for accessing and modifying guest disk images.
Amongst the things this is good for: making batch configuration
changes to guests, getting disk used/free statistics (see also:
virt-df), migrating between virtualization systems (see also:
clones, cloning guests and changing registry/UUID/hostname info, and
much else besides.

guest filesystem that Linux and qemu can, including but not limited
to: ext2/3/4, btrfs, FAT and NTFS, LVM, many different disk partition
schemes, qcow, qcow2, vmdk.

Notes on cross-architecture support
----------------------------------------------------------------------
At the moment we basically don't support cross-architecture or
32-on-64. This limits what is possible for some guests. Filesystem

The daemon/ directory contains its own configure script. This is so
that in future we will be able to cross-compile the daemon.
+Mirroring tip
+----------------------------------------------------------------------
+
+Having a local Fedora mirror makes a massive difference to the time it
+takes to build and rebuild initramfs images.
+
+Failing that, use squid to cache yum downloads, but read this first:
+https://lists.dulug.duke.edu/pipermail/yum/2006-August/009041.html
+(In brief, because yum chooses random mirrors each time, squid doesn't
+work very well with default yum configuration. To get around this,
+choose a Fedora mirror which is close to you, set this with
+'./configure --with-mirror=[...]', and then proxy the whole lot
+through squid by setting http_proxy environment variable).
+
+You will also need to substantially increase the squid configuration
+limits:

+
+IntelligentMirror is another possibility, although I couldn't get it
+to work for me.
