Overview of Kernel-Based Virtual Machine Environment
Cisco Catalyst 9800 Wireless Controller for Cloud is supported on top of Ubuntu, Red Hat Enterprise Linux (RHEL) 7.2, and Red Hat Enterprise Virtualization (RHEV) using the Kernel-Based Virtual Machine (KVM). Installation on a KVM requires the creation of a virtual machine (VM) and installation using a .iso file or a .qcow2 file. The VM can be launched using the KVM command line or Virsh.
-
.qcow2: Used for booting a software image in KVM environments.
-
.iso: Used to manually install the Cisco Catalyst 9800 Wireless Controller for Cloud using the Virsh tool. You must also have a virsh.xml file with a sample XML configuration to launch the controller in KVM environments using virsh commands.
