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

Hi,
Doesn't fly. Either every SCSI HBA uses QEMUSG64List (thus making this
aequivalent to the next option from the scsi point of view), or
scsi-disk would have to support both formats.
