Hi@akhtar,

The Hypervisor is defined as firmware or computer hardware used to provide virtual machine instances for the cloud computing instances and has different types of Hypervisors such as KVM, VMware, Containers, Xen, and Hyper-V which are explained as below –

  1. QEMU-KVM – This hypervisor is a virtualization layer in the Kernel-based Virtual Machine (KVM).

  2. VMWare – This hypervisor is of type ESXi Hypervisor and enterprise-class version hypervisor.

  3. Containers – This hypervisor is of cloud-native type hypervisor

  4. Xen– This hypervisor is of type microkernel designed that provides services which allow multiple computers operating systems to execute the processes on same computer hardware in concurrent mode.

You can check your hypervisor name in OpenStack using below command
