@var{aio} is "threads", or "native" and selects between pthread based disk I/O and native Linux AIO.
@item format=@var{format}
This option specifies the serial number to assign to the device.
@item addr=@var{addr}
Specify the controller's PCI address (if=virtio only).
+@item werror=@var{action},rerror=@var{action}
+Specify which @var{action} to take on write and read errors. Valid actions are:

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.
If your host crashes or loses power, then the guest may experience data
-corruption. When using the @option{-snapshot} option, writeback caching is
-used by default.
+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
an internal copy of the data.
+The host page cache can be avoided while only sending write notifications to
+the guest when the data has been reported as written by the storage subsystem
+using @option{cache=directsync}.
+
Some block drivers perform badly with @option{cache=writethrough}, most notably,
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,
+like your host losing power, the disk storage getting disconnected accidentally,
+etc. you're image will most probably be rendered unusable. When using
+the @option{-snapshot} option, unsafe caching is always used.
+
+Copy-on-read avoids accessing the same backing file sectors repeatedly and is
+useful when the backing file is over a slow network. By default copy-on-read
+is off.
+
Instead of @option{-cdrom} you can use:
@example
qemu -drive file=file,index=2,media=cdrom

+@item lossy
+
+Enable lossy compression methods (gradient, JPEG, ...). If this

+depending on its encoding settings. Enabling this option can save
+a lot of bandwidth at the expense of quality.
+
+@item non-adaptive
+
+Disable adaptive encodings. Adaptive encodings are enabled by default.
+An adaptive encoding will try to detect frequently updated screen regions,
+and send updates in these regions using a lossy encoding (like JPEG).
+This can be really helpful to save bandwidth when playing videos. Disabling
+adaptive encodings allows to restore the original static behavior of encodings
+like Tight.
+
+@item share=[allow-exclusive|force-shared|ignore]
+
+Set display sharing policy. 'allow-exclusive' allows clients to ask
+for exclusive access. As suggested by the rfb spec this is
+implemented by dropping other connections. Connecting multiple
+clients in parallel requires all clients asking for a shared session
+(vncviewer: -shared switch). This is the default. 'force-shared'
+disables exclusive client access. Useful for shared desktop sessions,
+where you don't want someone forgetting specify -shared disconnect
+everybody else. 'ignore' completely ignores the shared flag and
+allows everybody connect unconditionally. Doesn't conform to the rfb
+spec but is traditional qemu behavior.
