Which storage format is used when vManage is deployed as a virtual machine on a KVM hypervisor?

.iso is a format for optical disc images, primarily used for booting an operating system or installing software, not for virtual machine persistent disk storage.

.tgz is a compressed archive format (tar.gz) used for packaging files, not a virtual disk image format.

.ova is a package format for virtual appliances typically used with VMware or VirtualBox, often containing OVF descriptors and VMDK virtual disk files, but not directly for KVM's native disk format.

KVM hypervisors natively use the QCOW2 (.qcow2) format for virtual disk images, which is an open standard supporting features like snapshots and sparse allocation. Cisco provides the vManage virtual appliance image in .qcow2 format specifically for KVM deployments.
