Global Configuration Parameters

- About Global Configuration Parameters + About Configuration Parameters &PRODUCT; provides a variety of settings you can use to set limits, configure features, and enable or disable features in the cloud. Once your Management Server is running, you might - need to set some of these global configuration parameters, depending on what optional features - you are setting up. - To modify global configuration parameters, use the steps in "Setting Global Configuration - Parameters." + need to set some of these configuration parameters, depending on what optional features + you are setting up. + You can set default values at the global level, which will be in effect throughout the cloud unless you override them at a lower level. + You can make local settings, which will override the global configuration parameter values, at the level of an account, zone, cluster, or primary storage. The documentation for each &PRODUCT; feature should direct you to the names of the applicable - parameters. Many of them are discussed in the &PRODUCT; Administration Guide. The following table + parameters. The following table shows a few of the more useful parameters. - - Field - Value - + + Field + Value + - - management.network.cidr - A CIDR that describes the network that the management CIDRs reside on. This - variable must be set for deployments that use vSphere. It is recommended to be set for - other deployments as well. Example: 192.168.3.0/24. - - - xen.setup.multipath - For XenServer nodes, this is a true/false variable that instructs CloudStack to - enable iSCSI multipath on the XenServer Hosts when they are added. This defaults to false. - Set it to true if you would like CloudStack to enable multipath. - If this is true for a NFS-based deployment multipath will still be enabled on the - XenServer host. However, this does not impact NFS operation and is harmless. - - - secstorage.allowed.internal.sites - This is used to protect your internal network from rogue attempts to download - arbitrary files using the template download feature. This is a comma-separated list of CIDRs. - If a requested URL matches any of these CIDRs the Secondary Storage VM will use the private - network interface to fetch the URL. Other URLs will go through the public interface. - We suggest you set this to 1 or 2 hardened internal machines where you keep your templates. - For example, set it to 192.168.1.66/32. - - - use.local.storage - Determines whether CloudStack will use storage that is local to the Host for data - disks, templates, and snapshots. By default CloudStack will not use this storage. You should - change this to true if you want to use local storage and you understand the reliability and - feature drawbacks to choosing local storage. - - - host - This is the IP address of the Management Server. If you are using multiple - Management Servers you should enter a load balanced IP address that is reachable via - the private network. - - - default.page.size - Maximum number of items per page that can be returned by a CloudStack API command. - The limit applies at the cloud level and can vary from cloud to cloud. You can override this - with a lower value on a particular API call by using the page and pagesize API command parameters. - For more information, see the Developer's Guide. Default: 500. - - - ha.tag - The label you want to use throughout the cloud to designate certain hosts as dedicated - HA hosts. These hosts will be used only for HA-enabled VMs that are restarting due to the failure - of another host. For example, you could set this to ha_host. Specify the ha.tag value as a host tag - when you add a new host to the cloud. - + + management.network.cidr + A CIDR that describes the network that the management CIDRs reside on.
