Para Virtualization With Compiler Support

In paravirtualization guest OS is not completely isolated but it is partially isolated by the virtual machine from the virtualization layer and hardware. Visual MainWin offers a compiler support system to develop Windows applications using Visual Studio to run on some UNIX hosts.

A para-virtualized VM provides special APIs requiring substantial OS modifications in user applications. Para-Virtualization with Compiler Support While full virtualization architecture intercepts and emulates privileged and sensitive instructions at runtime para-virtualization handles these instructions at compile time. Para-virtualization attempts to reduce the virtualization overhead and thus improve performance by modifying only the guest.

KVM can support hardware-assisted virtualization by using the Intel VT-x or AMD-v and. It sees underlying hypervisor. Guest OS is modified and optimized.
