Add <features> and <compat> elements to volume target XML. <compat> is a string which for qcow2 represents the QEMU version it should be compatible with. Valid values are 0.10 and 1.1. 1.1 is implicit if the <features> element is present, otherwise qemu-img default is used. 0.10 can be specified to explicitly create older images after the qemu-img default changes. <features> contains optional features, so far <lazy_refcounts/> is available, which enables caching of reference counters, improving performance for snapshots.
