The disadvantages of using virtuozzo are as follows:

• Flexibility: flexibility decreases due to operating system virtualization as all the containers uses the same operating system.

• Virtuozzo containers can't use different operating system and have different configurations.

• It can't virtualize the systems at high scale as it will require more resources.

• It can't run high end operating system or else there is a degrade in the performance of the systems.

• The connectivity of the system is such that it can communicate only in a small range and doesn't have very high-end tool to manage the changes.
