Subject: [PATCH] Rewrite virt-cat in C.
With changes in the core API since 1.5, virt-cat was little
more than a Perl wrapper which did some command line argument
processing. Thus it could easily be rewritten in C.
This version also shares core command line argument processing
with guestfish and guestmount, so the options have changed
slightly (old-style command line *is* supported).
virt-cat -a disk.img file [file ...]
virt-cat -d domname file [file ...]
Several other guestfish options are supported including encryption,
and with the new style multiple files can be downloaded. See the
man page for details.

+=head1 NAME
+
+virt-cat - Display files in a virtual machine
+
+=head1 SYNOPSIS
+
+ virt-cat [--options] -d domname file [file ...]
+
+ virt-cat [--options] -a disk.img [-a disk.img ...] file [file ...]
+
+Old-style:
+
+ virt-cat domname file
+
+ virt-cat disk.img file
+
+=head1 DESCRIPTION
+
+C<virt-cat> is a command line tool to display the contents of
C<file>
+where C<file> exists in the named virtual machine (or disk image).
+
+Multiple filenames can be given, in which case they are concatenated
+together. Each filename must be a full path, starting at the root
+directory (starting with '/').
+
+C<virt-cat> can be used to quickly view a file. To edit a file, use
+C<virt-edit>. For more complex cases you should look at the
+L<guestfish(1)> tool.
+
+=head1 EXAMPLES
+
+Display C</etc/fstab> file from inside the libvirt VM called
+C<mydomain>:
+
+ virt-cat -d mydomain /etc/fstab
+
+List syslog messages from a VM disk image file:
+
+ virt-cat -a disk.img /var/log/messages | tail
+
+Find out what DHCP IP address a VM acquired:
+
+ virt-cat -d mydomain /var/log/messages | \
+ grep 'dhclient: bound to' | tail
+
+Find out what packages were recently installed:
+
+ virt-cat -d mydomain /var/log/yum.log | tail
+
+Find out who is logged on inside a virtual machine:
+
+ virt-cat -d mydomain /var/run/utmp > /tmp/utmp
+ who /tmp/utmp
+
+or who was logged on:
+
+ virt-cat -d mydomain /var/log/wtmp > /tmp/wtmp
+ last -f /tmp/wtmp
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<--help>
+
+Display brief help.
+
+=item B<-a> file
+
+=item B<--add> file
+
+Add I<file> which should be a disk image from a virtual machine. If
+the virtual machine has multiple block devices, you must supply all of
+them with separate I<-a> options.
+
+The format of the disk image is auto-detected. To override this and
+force a particular format use the I<--format=..> option.
+
+=item B<-c> URI
+
+=item B<--connect> URI
+
+If using libvirt, connect to the given I<URI>. If omitted, then we
+connect to the default libvirt hypervisor.
+
+If you specify guest block devices directly (I<-a>), then libvirt is
+not used at all.
+
+=item B<-d> guest
+
+=item B<--domain> guest
+
+Add all the disks from the named libvirt guest.
+
+=item B<--echo-keys>
+
+When prompting for keys and passphrases, virt-cat normally turns
+echoing off so you cannot see what you are typing. If you are not
+worried about Tempest attacks and there is no one else in the room you
+can specify this flag to see what you are typing.
+
+=item B<--format=raw|qcow2|..> | B<--format>
+
+The default for the I<-a> option is to auto-detect the format of the
+disk image. Using this forces the disk format for I<-a> options which
+follow on the command line. Using I<--format> with no argument
+switches back to auto-detection for subsequent I<-a> options.
+
+For example:
+
+ virt-cat --format=raw -a disk.img
+
+forces raw format (no auto-detection) for C<disk.img>.
+
+ virt-cat --format=raw -a disk.img --format -a another.img
+
+forces raw format (no auto-detection) for C<disk.img> and reverts to
+auto-detection for C<another.img>.
+
+If you have untrusted raw-format guest disk images, you should use
+this option to specify the disk format. This avoids a possible
+security problem with malicious guests (CVE-2010-3851). See also
+L</add-drive-opts>.
+
+=item B<--keys-from-stdin>
+
+Read key or passphrase parameters from stdin. The default is
+to try to read passphrases from the user by opening C</dev/tty>.
+
+=item B<-v>
+
+=item B<--verbose>
+
+Enable verbose messages for debugging.
+
+=item B<-V>
+
+=item B<--version>
+
+Display version number and exit.
+
+=item B<-x>
+
+Enable tracing of libguestfs API calls.
+
+=back
+
+=head1 OLD-STYLE COMMAND LINE ARGUMENTS
+
+Previous versions of virt-cat allowed you to write either:
+
+ virt-cat disk.img [disk.img ...] file
+
+or
+
+ virt-cat guestname file
+
+whereas in this version you should use I<-a> or I<-d> respectively
+to avoid the confusing case where a disk image might have the same
+name as a guest.
+
+For compatibility the old style is still supported.
+
+=head1 SHELL QUOTING
+
+Libvirt guest names can contain arbitrary characters, some of which
+have meaning to the shell such as C<#> and space. You may need to
+quote or escape these characters on the command line. See the shell
+manual page L<sh(1)> for details.

-=head1 NAME
-
-virt-cat - Display a file in a virtual machine
-
-=head1 SYNOPSIS
-
- virt-cat [--options] domname file
-
- virt-cat [--options] disk.img [disk.img ...] file
-
-=head1 DESCRIPTION
-
-C<virt-cat> is a command line tool to display the contents of
C<file>
-where C<file> exists in the named virtual machine (or disk image).
-
-C<virt-cat> can be used to quickly view a single file. To edit a
-file, use C<virt-edit>. For more complex cases you should look at the
-L<guestfish(1)> tool.
-
-=head1 EXAMPLES
-
-Display C</etc/fstab> file from inside the libvirt VM called
-C<mydomain>:
-
- virt-cat mydomain /etc/fstab
-
-List syslog messages from a VM:
-
- virt-cat mydomain /var/log/messages | tail
-
-Find out what DHCP IP address a VM acquired:
-
- virt-cat mydomain /var/log/messages | grep 'dhclient: bound to' | tail
-
-Find out what packages were recently installed:
-
- virt-cat mydomain /var/log/yum.log | tail
-
-Find out who is logged on inside a virtual machine:
-
- virt-cat mydomain /var/run/utmp > /tmp/utmp
- who /tmp/utmp
-
-or who was logged on:
-
- virt-cat mydomain /var/log/wtmp > /tmp/wtmp
- last -f /tmp/wtmp

-=head1 OPTIONS
-
-=over 4
-
-=cut
-
-my $help;
-
-=item B<--help>
-
-Display brief help.
-
-=cut
-
-my $version;
-
-=item B<--version>
-
-Display version number and exit.
-
-=cut
-
-my $uri;
-
-=item B<--connect URI> | B<-c URI>
-
-If using libvirt, connect to the given I<URI>. If omitted, then we
-connect to the default libvirt hypervisor.
-
-If you specify guest block devices directly, then libvirt is not used
-at all.
-
-=cut
-
-my $format;
-
-=item B<--format> raw
-
-Specify the format of disk images given on the command line. If this
-is omitted then the format is autodetected from the content of the
-disk image.
-
-If disk images are requested from libvirt, then this program asks
-libvirt for this information. In this case, the value of the format
-parameter is ignored.
-
-If working with untrusted raw-format guest disk images, you should
-ensure the format is always specified.

-=head1 SHELL QUOTING
-
-Libvirt guest names can contain arbitrary characters, some of which
-have meaning to the shell such as C<#> and space. You may need to
-quote or escape these characters on the command line. See the shell
-manual page L<sh(1)> for details.
