Unfortunately the message gives no details:
"libvirtError: internal error unable to start guest:"

What did you change that made it work?

Libvirt keeps log files for each VM under
/var/log/libvirt/qemu/<domain>.log.  You might find more detailed
error information in that file and it will at least contain the
qemu-kvm command-line used to launch the domain.  Please take a look
at that file and post the lines surrounding the error, especially the
"starting up" log line.

Have you verified that the .qcow2 image file is accessible, ownership
and permissions should be the same as the image files of your other
domains.
