It helps you also to configure, monitor, and manage kernel-based virtual machines. Oracle Linux Virtualization Manager comes with enhanced features to deliver leading performance and security features embedded inside it. It is including the support for Intel VT-x and VT-d hardware extension.
VTX helps make virtual machines. It lets different operating systems run together on one computer. It works by creating a virtual processor for each virtual machine. This means each virtual machine can run its own programs and system. VTD helps with input/output device virtualization.
It allows VMs to directly use certain devices like graphic cards, network adapters, and storage controllers. This makes I/O tasks faster because the hypervisor doesn’t have to translate requests between the VM and the device. In short, the VTX does processor level virtualization and VTD helps with device virtualization. Both are important for making virtualization work well and fast.
On a computer using x86 architectures, each CPU core is treated as a separate physical CPU by the software that manages virtual machines or the main operating systems. Virtual CPUs, also called as vCPUs, are what the guest virtual machine sees as its CPU.
The guest VM decides which tasks run on these virtual CPUs, and the software managing, the VM, decides which physical CPU cores or threads these vCPUs use. Oracle Linux KVM comes with a cool feature called hard partitioning, also known as CPU pinning.
Hard partitioning means assigning a specific vCPU to certain physical CPU threads or cores. This prevents those vCPUs from being moved to other CPU threads or cores, ensuring they stay where you want them to be, which is essential for licensing Oracle products based on the number of physical cores in use.
Data center administrators can use Oracle Linux Virtualization Manager built from the open-source project to manage and support multiple host running Oracle Linux KVM.
