virt-tar-out(1) Virtualization Support virt-tar-out(1)
NAME
virt-tar-out - Pack a virtual machine disk image directory into a tarball.
SYNOPSIS
virt-tar-out -a disk.img /dir files.tar
virt-tar-out -d domain /dir files.tar
virt-tar-out -d domain /dir - | gzip --best > files.tar.gz
DESCRIPTION
"virt-tar-out" packs a virtual machine disk image directory into a tarball.
The first parameter is the absolute path of the virtual machine directory. The second parameter is the tar file to write. Use "-" to
write to standard output.
EXAMPLES
Download the home directories from a guest:
virt-tar-out -d MyGuest /home - | gzip --best > homes.tar.gz
JUST A SHELL SCRIPT WRAPPER AROUND GUESTFISH
This command is just a simple shell script wrapper around the guestfish(1) "tar-out" command. For anything more complex than a trivial
copy, you are probably better off using guestfish directly.
OPTIONS
Since the shell script just passes options straight to guestfish, read guestfish(1) to see the full list of options.
SEE ALSO
guestfish(1), virt-cat(1), virt-copy-in(1), virt-copy-out(1), virt-edit(1), virt-tar-in(1), <http://libguestfs.org/>.
