Troubleshooting tips

• Image won’t boot: verify checksum, ensure virtualization extensions (VT-x/AMD-V) enabled.
• Networking not reachable: check qemu network mode (user vs. bridge) and host firewall.
• Performance poor: increase RAM/CPU or use virtio drivers and proper NIC model.

• Boot Loops: If the Qcow2 file is corrupted during download, the VM may boot loop. Always verify the MD5 or SHA checksum of the file against the source.
• Resource Allocation: This image requires dedicated RAM. If your host machine lacks sufficient memory, the image will fail to start or run extremely slowly.
• CPU Compatibility: Ensure your computer's CPU supports virtualization extensions (VT-x for Intel or AMD-V for AMD) and that these are enabled in the BIOS.

• KVM (native)
• Proxmox VE (import as QEMU image)
• GNS3 (import via QEMU appliance)
• EVE-NG (Community and Pro editions)
• Cisco CML (formerly VIRL)
