NAME

6       nbdkit-memory-plugin - nbdkit virtual memory plugin
7

SYNOPSIS

9        nbdkit memory size=SIZE
10

DESCRIPTION

12       "nbdkit-memory-plugin" is a plugin for nbdkit(1) which stores a single
13       disk image in virtual memory, and discards it when nbdkit exits.
14
15       All nbdkit clients will see the same disk content, initially all
16       zeroes.
17
18       The disk image is stored in memory so it cannot be larger than physical
19       RAM plus swap, less whatever is being used by the rest of the system.
20       Very large disk image sizes will usually not work with this plugin (use
21       nbdkit-file-plugin(1) backed by a temporary file for that).
22
23       This can be used for testing where you don't care about the final
24       content of the disk image.
25

PARAMETERS

27       size=SIZE
28           Specify the virtual size of the disk image.

30           This parameter is required.
