If you do 'git grep detect-zeroes' in libvirt git, you will
find we only
have that string in the tests, particularly in files with replies from
various qemu versions. That way you can say that libvirt does not
provide the possibility to do so. However, the patches for adding that
support are very trivial, so I took the liberty of adding it, see here:
https://www.redhat.com/archives/libvir-list/2015-December/msg00484.html
Thanks for help! =) In case of blockcopy and lvm thin pools this is
very useful feature.
