Red Hat Enterprise Virtualization provides a resource-limitation tool called quota, which allows system administrators to limit the amount of CPU and storage each user can consume. Quota compares the amount of virtual resources consumed when you use the virtual machine to the storage allowance and the run-time allowance set by the system administrator.
When you exceed your quota, a pop-up window informs you that you have exceeded your quota, and you will no longer have access to virtual resources. For example, this can happen if you have too many concurrently running virtual machines in your environment.
To regain access to your virtual machines, do one of the following:
- Shut down the virtual machines that you do not need. This will bring your resource consumption down to a level at which it is not in excess of the quota, and you will be able to run virtual machines again.
- If you cannot shut down any existing virtual machines, contact your system administrator to extend your quota allowance or remove any unused virtual machines.
