Paravirtualization, on the other hand, is a lighter form of virtualization. This technique is fast and provides near native speed in comparison to full virtualization. With Paravirtualization, the guest operating system requires some modification before everything can work. These modifications allow the hypervisor to export a modified version of the underlying hardware to the VMs, allowing them near-native performance. All PV machines running on a hypervisor are basically modified operating systems like Solaris or various Linux distributions.
While the performance of this virtual system is not equal to the performance of the operating system running on true hardware, the concept of virtualization works because most guest operating systems and applications don't need the full use of the underlying hardware.
