OpenStack Folsom has a BUG, that is Fixed_Ips quota issue
Check out the official documentation obtained, the default quota of quota OpenStack
Table 3.1. Description of nova.conf file configuration options for quotas
Configuration option = Default value (Type) Description
quota_cores = 20
(IntOpt) number of instance cores allowed per project (tenant)

Which does not indicate Fixed_Ips parameters and configuration, and use in Dashboard Administrator console to view the default when the default Quota
In the Project can Modify Quotas functionality of the console, also found no editable items Fix_Ips
Now and then configure official Nova documentation indicating Quotas default values can be configured by modifying the configuration file /etc/nova/nova.conf nova official documents Address: http: //docs.openstack.org/folsom/openstack-compute/admin/ content / list-of-compute-config-options.html, where quotas on the configuration parameters as follows:
Table 5.8. Description of nova.conf file configuration options for quotas

Look carefully, none of which about Fixed_Ips configuration, more doubts, but the problem does not exist, create an error occurs when more than 10 instances in the Project, the log shows the error reads as follows:

Puzzling, Google has not found the problem, the official said only bug fixes have modified the BUG, and in the latest version of Grizzly has no such problem, but did not give Folsom and Essex Edition version of the solution, so , take chances, according to official documents Quota other configuration parameters in the file, add a nova.conf configuration:
quota_fixed_ips = 100
Then restart nova Service
cd /etc/init.d/; for i in $ (ls nova- *); do sudo service $ i restart; done
In the control nodes and network nodes perform again, back to the Dashboard console and saw Quotas in Fixed Ips has changed, and then create an instance of the normal, the problem is solved. |
