[fedora-virt] QCOW2 vs QROW2 Disks

[Jorge Fábregas]

Hi there,

I'm just curious:  Where does the "Copy on Write" (from QCOW) comes
from?  Everything I've been reading regarding how snapshots work with
QEMU points to a "redirect on write" approach.  Or is the COW part
related to some other internal mechanism (not related to snapshots)?

Thanks in advance,
Jorge
