     284== Managing Quotas ==
     285Openstack enforces quotas at the slice (project) level and at the server level.
     286
     287To view the default quotas, use the following command:
     288{{{
     289source /etc/novarc
     290nova quota-defaults
     291}}}
     292
     293To update the default quota, use the following command:
     294{{{
     295nova quota-class-update --key value default
     296}}}
     297See here for more details:
     298http://docs.openstack.org/user-guide-admin/content/cli_set_quotas.html
     299
     300There is also a notion of absolute limits on quota. The default quota
     301cannot exceed the absolute limits.
     302To view the absolute limit quota, use the following command:
     303{{{
     304nova absolute-limits
     305}}}
     306
     307To change the value of the absolute-limits you must edit /etc/nova/nova.conf on the control node and restart the nova-api service.
     308For example, you can add these lines to set the number of cores and RAM:
     309{{{
     310quota_ram=512000
     311quota_cores=150
     312}}}
     313
     314Further, there is a notion of overcommitting in OpenStack and this too has a limit.
     315See here for details: http://docs.openstack.org/openstack-ops/content/compute_nodes.html
