List all VMs:
To guarantee boot sequence initialization and operational stability within a hypervisor, you must meet the following minimum resource requirements: Resource Metric Minimum Lab Target Production Baseline 2 to 4 Cores (Scales with License) System Memory 2048 MB (2 GB) 4096 MB (4 GB) or Higher Primary Boot Drive 100 MB or larger 100 MB (Automatically mapped) Secondary Log Disk 10 GB to 30 GB 30 GB to 120 GB (VirtIO type) Virtual NICs 4 Adapters minimum Up to 10 Adapters (VirtIO drivers) fgtvm64kvmv723fbuild1262fortinetoutkvmqcow2
For a stable deployment of the KVM QCOW2 image, ensure your host environment meets the following minimum specs: : KVM (QEMU 2.12 or later recommended). List all VMs: To guarantee boot sequence initialization
FortiGate VM memory allocation directly affects concurrent session capacity. For a small branch, 4 GB is fine; for a data center, consider 8–16 GB. FortiOS 7
FortiOS 7.2.3 build 1262 includes virtio-net and virtio-blk support.
The QCOW2 format offers snapshot capabilities and sparse allocation, saving disk space until data is written. For production, many users convert fgtvm64kvmv723fbuild1262fortinetoutkvmqcow2 to a raw image if maximum I/O performance is needed (use qemu-img convert ).
Always use VirtIO for both disk and network interfaces to ensure the highest possible throughput .
