Why each option
Cisco SD-WAN controllers are deployed as virtual machines using .qcow2 (KVM) and .ova (VMware/hypervisor) image formats.
.nxos is the firmware image format specific to Cisco Nexus switches running NX-OS and is not used for SD-WAN controller deployment.
.qcow2 is the QEMU Copy-On-Write disk image format used to deploy SD-WAN controller VMs on KVM-based hypervisors.
.iso is a generic optical disk image format and is not the supported format for deploying Cisco SD-WAN controller instances.
.ova is the Open Virtualization Archive format used to deploy SD-WAN controller VMs on VMware ESXi and other compatible hypervisors.
.tgz is a compressed tar archive format used for file bundling, not a recognized VM image format for SD-WAN controller deployment.
