The QCOW2 format (QEMU Copy-On-Write version 2) is the native disk image format for QEMU and KVM. For Fortinet, the fortios.qcow2 file is the bootable system disk that contains the entire FortiOS operating system. When you download a KVM deployment package from Fortinet, typically named FGT_VM64_KVM-vX.Y.Z-build-XXXX-FORTINET.out.kvm.zip , the only file contained within the zip archive is fortios.qcow2 [11†L3-L5]. This compact format allows for efficient storage because it uses copy-on-write, supports snapshots, and can be compressed or encrypted.
Attach the fortios.qcow2 file as the primary IDE or VirtIO drive. 3. Initial Boot and CLI Configuration
Which are you using (Proxmox, GNS3, or pure KVM)? Are you setting this up for a home lab or production ? fortios.qcow2

Once the VM boots, the default credentials are usually admin with no password, though newer versions prompt for a mandatory password change on first login [0†L34-L35][8†L31]. The QCOW2 format (QEMU Copy-On-Write version 2) is
Deploying a FortiGate-VM using fortios.qcow2 involves importing the disk image into your hypervisor. Below is a generic workflow for KVM-based systems. Prerequisites
Rename the file inside the directory to . FortiOS expects the boot drive to be the first virtual drive element. Fix permissions via the EVE-NG CLI tool: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions Use code with caution. This compact format allows for efficient storage because
format is its portability across the most popular network simulation platforms: Lab pros often rename this file to virtioa.qcow2 to integrate it into EVE-NG nodes

Avoid CPU overcommit. Pin dedicated vCPUs to physical cores using virsh vcpupin or the cpuset= option in the domain XML.
