Hello All, I had a doubt about the COW implementation of QCOW2. Suppose two clusters point to the same address, then in that case, the QCOW_OFLAG_COPIED is cleared in the l2 entries for both the clusters. Now suppose a write is made to any one of the clusters, then how is the other cluster identified, in order to set the QCOW_OFLAG_COPIED since only reference is left.
Thanks in advance, Furquan
