It's not good to change the default behavior, if someone wants
preserve, make them specify it in the XML.

not an issue, since it's a fairly small patch, but one could imagine to
split it up into a 3-part series: general libvirt, qemu and virsh.

see above, it's not good to change defaults, plus make check fails
with this hunk applied.

Other than that looks good to me (Tested on s390x with destroy, reboot
and preserve). Looking forward to see this in libvirt.
