By default, writethrough caching is used for all block device. This means that
Writeback caching will report data writes as completed as soon as the data is
present in the host page cache. This is safe as long as you trust your host.

-corruption. When using the @option{-snapshot} option, writeback caching is

+corruption.
The host page cache can be avoided entirely with @option{cache=none}. This will
attempt to do disk IO directly to the guests memory. QEMU may still perform
qcow2. If performance is more important than correctness,
@option{cache=writeback} should be used with qcow2.
+In case you don't care about data integrity over host failures, use
+cache=unsafe. This option tells qemu that it never needs to write any data
+to the disk but can instead keeps things in cache. If anything goes wrong,

+etc. you're image will most probably be rendered unusable. When using
