What is Kubevirt?
KubeVirt is a Kubernetes CRD(Custom Resource Definitions) implement. It is a virtual machine management add-on for Kubernetes. The aim is to provide a common ground for virtualization solutions on top of Kubernetes.
In details, KubeVirt technology addresses the needs of development teams that have adopted or want to adopt Kubernetes but possess existing Virtual Machine-based workloads that cannot be easily containerized. So KubeVirt extends Kubernetes by adding additional virtualization resource types (especially the VM/VMI type) through Kubernetes's Custom Resource Definitions API. By using this mechanism, the Kubernetes API can be used to manage these VM resources alongside all other resources Kubernetes provides. The resources themselves in Kubernetes are not enough to launch virtual machines. For this to happen, the functionality and business logic needs to be added to the cluster. Scheduling, networking, and storage are all delegated to Kubernetes, while KubeVirt provides the virtualization functionality. The functionality is not added to Kubernetes itself, but rather added to a Kubernetes cluster by running additional controllers and agents on an existing cluster. And these necessary controllers and agents are all provided by KubeVirt.

Intel QuickAssist Technology is developed by Intel and runs on the Intel Architecture to provide security and compression acceleration capabilities to improve performance and efficiency. It will offload the workloads like cryptography and compression from the CPU to handware. Server, networking, big data, and storage applications use Intel QuickAssist to offload compute-intensive operations, such as:
- Symmetric cryptography functions, including cipher operations and authentication operations
- Public key functions, including RSA, Diffie-Hellman, and elliptic curve cryptography,
- Compression and decompression functions, including DEFLATE
It has made great benefits in many areas, such as Hadoop Acceletation, OpenSSL Integration, SDN and NFV Solutions Boost and so on.
