• Virtuozzo containers produce the virtualization at operating system level so they are called as type-2 Hypervisors, whereas ESX server produce the virtualization at hardware level and they are called as type-1 Hypervisors.

• Virtuozzo provides low overhead compared to ESX server due to hardware level configurations.

• Virtuozzo provides high performance and high resources at lower cost compared to ESX server.

• Virtuozzo's containers provide the virtualization at the same level and there is no need for hardware virtualization, whereas ESX server has to be configured at the hardware level to produce the resources.
