+ The block tap driver is an alternative to the block back driver
+ and allows VM block requests to be redirected to userspace through
+ a device interface. The tap allows user-space development of
+ high-performance block backends, where disk images may be implemented
+ as files, in memory, or on other hosts across the network. This
+ driver can safely coexist with the existing blockback driver.
