for a single user from the command line

57 |
The file must contain non-empty lines, and each line must
|
58 |
contain a single-space-separated list of values:
|
59 |
|
60 |
<user> <resource name> <capacity> <quantity> <import_limit> <export_limit>
|
61 |
|
62 |
For example to grant the following user with 10 private networks
|
63 |
(independent of any he receives from projects):
|
64 |
|
65 |
6119a50b-cbc7-42c0-bafc-4b6570e3f6ac cyclades.network.private 10 0 1000000 1000000
|
66 |
|
67 |
The last two values are arbitrarily large to represent no
|
68 |
import/export limit at all.
|
69 |
|
70 |
When setting quota from the command line, specify only capacity.
|
71 |
Quantity and import/export limit will get default values. Example:
|
72 |
|
73 |
--set-capacity 6119a50b-cbc7-42c0-bafc-4b6570e3f6ac cyclades.vm 10
