The main goal of resource control in Parallels Server Bare Metal is to provide Service Level
Management or Quality of Service for virtual machines and Containers. Correctly configured
resource control settings prevent serious impacts resulting from the resource over-usage
(accidental or malicious) of any virtual machine and Container on the other virtual machines and
Containers. Using resource control parameters for resources management also allows you to
enforce fairness of resource usage among virtual machines and Containers and better service
quality for preferred virtual machines and Containers, if necessary.

What are Resource Control
Parameters?
The system administrator can control the resources available to a virtual machine and Container
through a set of resource management parameters. All these parameters can be set and
configured as follows:
 For Containers, by manually editing the global (/etc/vz/vz.conf) and Container
(/etc/vz/conf/CT_ID) configuration files or using the Parallels Server Bare Metal
command-line utilities.
 For virtual machines, by manually editing virtual machine configuration files
(/etc/vz/VM_Name.pvm/config.pvs) or using the Parallels Server Bare Metal
command-line utilities.
The following sections describe in detail how to configure resource parameters for both virtual
machines and Containers.
