| 57 | +.SH "SYNOPSIS" | ||

| 59 | +\fBqemu-mkcow\fR [\fB-h\fP] [\fB-f \fImaster_disk_image\fR\fP] [\fIcow_image\fR] [\fB\fIcow_size\fR\fP] | ||
| 60 | +.SH "DESCRIPTION" | ||
| 61 | +.PP | ||
| 62 | +The \fBqemu-mkcow\fR command creates a | ||
| 63 | +persistent copy-on-write file for \fBqemu\fR. | ||
| 64 | + | ||
| 65 | +.PP | ||
| 66 | +\fBqemu\fR can be used in a "copy-on-write" mode, | ||
| 67 | +where changes made by \fBqemu\fR do not actually | ||
| 68 | +change the disk image file. One way is to invoke | ||
| 69 | +\fBqemu\fR with -snapshot: these changes | ||
| 70 | +are stored in a temporary file, which is discarded when | ||
| 71 | +\fBqemu\fR exits. | ||
| 72 | + | ||
| 73 | +.PP | ||
| 74 | +\fBqemu-mkcow\fR creates an explicit copy-on-write | ||
| 75 | +file where changes are to be stored: this way, changes made | ||
| 76 | +inside \fBqemu\fR will still be there next time you | ||
| 77 | +run it, although the master disk image isn't ever changed. | ||
| 78 | + | ||
| 79 | +.PP | ||
| 80 | +The usual method is to create the master image, then create a | ||
| 81 | +copy-on-write file using \fBqemu-mkcow\fR with | ||
| 82 | +\fB-f\fP. The filename of the master image is stored | ||
| 83 | +inside the generated copy-on-write file: it must not be modified | ||
| 84 | +after this is run! | ||
| 85 | + | ||
| 86 | +.PP | ||
| 87 | +If no master file is specified, the effect is that of a | ||
| 88 | +blank master of size \fIcow_size\fR. | ||
