nbdkit-memory-plugin — nbdkit virtual memory plugin
nbdkit memory size=SIZE
"nbdkit-memory-plugin" is a plugin for nbdkit(1) which stores a single disk image in virtual memory, and discards it when nbdkit exits.
All nbdkit clients will see the same disk content, initially all zeroes.
The disk image is stored in memory so it cannot be larger than physical RAM plus swap, less whatever is being used by the rest of the system. Very large disk image sizes will usually not work with this plugin (use nbdkit-file-plugin(1) backed by a temporary file for that).
This can be used for testing where you don't care about the final content of the disk image.
Specify the virtual size of the disk image.
This parameter is required.
