When possible, make the disk image format explicit when invoking tools or using add-drive. This avoids warnings from qemu about the unspecified format for the image, and also makes qemu slightly faster (skipping the disk image probing). Tests checking the image probing are not touched. This changes also: - old-style invocations of tools (`$tool $filename`) into new style (`$tool -a $filename`) - add-drive-ro/add-drive-with-if guestfish commands into add/add-drive with explicit readonly/iface arguments There should be no change in the tests results.
This is the third rewrite of the virt-df program. It very much
follows the outline of the Perl program which this replaced in
libguestfs 1.7.14.
main.c - main program
domains.c - dealing with libvirt, only used if libvirt is around
at compile time
df.c - getting the stats from libguestfs
output.c - writing the output, CSV output
virt-df.h - header file
Note this also uses the shared options parsing code in
'fish/options.[ch]'.
