How to enable quotas on Virtuozzo environments on Virtuozzo 7

Introduction

If you have a Virtuozzo 7 VPS, there are a few steps that must be taken to enable quotas in this environment.

This is due to the nature of Virtuozzo quota types.

What is a container? 

The container is a spun up virtualized instance. This instance is going to be the virtual server in which you will be hosting your website, emails, databases, and other various web hosting information. 

Procedure

Finding the Container UUID

You will need to find the container UUID. This can be achieved by running the following command: 

# prlctl list -a
UUID                                    STATUS    IP_ADDR        T   NAME
{600adc12-0e39-41b3-bf05-c59b7d26dd73}  running   10.10.1.101    CT  MyCT
{b2de86d9-6539-4ccc-9120-928b33ed31b9}  stopped   10.10.100.1    VM  MyVM

We can see the first entry in bold is the UUID, which is the Container_ID. 

Enabling Quotas

Perform the following steps:

1. Set the QUOTAUGIDLIMIT parameter to a value that is greater than zero. This can be seen below in step 2.

2. Run the following command to enable quotas, where UUID represents the container ID of the container that you wish enable quotas on.

   prlctl set <UUID> --quotaugidlimit 1

3. Restart the Container.

    prlctl restart UUID
