I successfully test restored four of my main VM
disk files after converting them to "raw".
It may just be my perception, but I think raw
just might be faster than qcows2
For many workloads it probably is, as qcow adds a layer of indirection
to filesystem access. However qcow also allows compression, sparse
files, encryption and copy-on-write snapshots (COW, hence the name)
independently of whether the underlying guest system supports these
things.
