The <option>-H</option> and <option>-B</option> options |
|
| 1390 |
specify extra, temporary hypervisor and backend parameters |
|
| 1391 |
that can be used to start an instance with modified |
|
| 1392 |
parameters. They can be useful for quick testing without |
|
| 1393 |
having to modify an instance back and forth, e.g.: |
|
| 1394 |
<screen> |
|
| 1395 |
# gnt-instance start -H root_args="single" instance1 |
|
| 1396 |
# gnt-instance start -B memory=2048 instance2 |
|
| 1397 |
</screen> |
|
| 1398 |
The first form will start the instance |
|
| 1399 |
<userinput>instance1</userinput> in single-user mode, and |
|
| 1400 |
the instance <userinput>instance2</userinput> with 2GB of |
|
| 1401 |
RAM (this time only, unless that is the actual instance |
|
| 1402 |
memory size already). |
