Since ls is run twice, there's a race condition. If a directory is deleted in the meantime, a directory that should have been kept will be nuked. Similarly, if a directory is added in the meantime, a directory that should have been removed will persist.
There is no need to run ls twice. You can just use tail's ability to index releative to the beginning of the data, tail -n +10 versus tail -n 10. However, this approach still requires some arithmetic, since skipping the first x lines requires an option argument of x+1.
I wouldn't bother with tail. In my opinion, the simplest solution is to use sed:
Note that xargs does not play well with filenames containing whitespace or quotes. If such filenames occur, instead of xargs, a less efficient while-read loop would be necessary.

virt-copy-out
virt-copy-out(1) Virtualization Support virt-copy-out(1)NAME
virt-copy-out - Copy files and directories out of a virtual machine disk image.
SYNOPSIS
virt-copy-out -a disk.img /file|dir [/file|dir ...] localdir
virt-copy-out -d domain /file|dir [/file|dir ...] localdir
DESCRIPTION
"virt-copy-out" copies files and directories out of a virtual machine disk image or named libvirt domain.
You can give one of more filenames and directories on the command line. Directories are copied out recursively.
EXAMPLES
Download the home directories from a virtual machine:
mkdir homes
virt-copy-out -d MyGuest /home homes
JUST A SHELL SCRIPT WRAPPER AROUND GUESTFISH
This command is just a simple shell script wrapper around the guestfish(1) "copy-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.
