Setting Up Reservation Manager › Post-Installation Configuration › Set Limits on Virtual Machine Resources

Set Limits on Virtual Machine Resources

Administrators can set limits on the number of VMs deployed simultaneously, the number of CPUs, the amount of memory, and the number of disks a user can request when reserving virtual machines.

To set limits on virtual machine resources

1. Log in to the Reservation Manager using the CA Server Automation administrator user credentials.

   The home page opens.

2. Click Administer Your Reservation Manager.

   The Administration page opens.

3. Click Manage your configuration settings.

   The Configure Settings page opens.

4. Click the following links in the Virtual Machines area. Each one opens a dialog in which you can change the value and click OK.

   Maximum Virtual Center Workload

   Controls how many VMs can be deployed simultaneously within one VMware vCenter or vSphere. By default, no limit is set. Setting a limit may be desirable to increase overall throughput in your vCenter environment. A value of 0 or -1 indicates that no limit is set. A value greater than 0 limits the number of simultaneous deployments within a vCenter to the specified value. The Apache service must be recycled for the changes to take effect.

   Default: -1 (no limit)

   Note: This configuration setting does not apply to Hyper-V.

   Virtual CPU Limit

   Specifies the maximum number of CPUs that users can request when making virtual machine reservations. A value of 0 or -1 indicates no limit.

   Default: -1 (no limit)

   Virtual Memory Limit

   Specifies the maximum amount of memory (MB) that users can request when making virtual machine reservations. A value of 0 or -1 indicates that no limit is set.

   Default: -1 (no limit)

   Virtual Disk Limit

   Specifies the maximum number of disks that users can request when making virtual machine reservations. A value of 0 or -1 indicates there is no limit as long as enough space is available.

   Default: -1 (no limit)

   Virtual Disk Space Limit

   Specifies the maximum amount of disk space (GB) that users can request when making virtual machine reservations. A value of 0 or -1 indicates no limit.

   Default: -1 (no limit)

   The configuration changes take effect when the next reservation is made.
