To guarantee that the QEMU hypervisor can execute the virtual image smoothly without locking up, trigger EVE-NG's automated permission fix command: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions Use code with caution. Optimization Practices for Enterprise Labs
The cat9kv-prd-17.12.01prd9.qcow2 file is resource-heavy because it attempts to emulate complex ASIC logic in software. Running a multi-node environment requires a robust bare-metal server or hypervisor with the following specifications: Catalyst 9000v - - EVE-NG List if the

If the node loops indefinitely at the ROMMON boot loader screen or crashes midway through unpacking the system image file ( bootflash:packages.conf ), your host computer is choking on RAM or CPU cycles. Ensure you have allocated a full and that nested virtualization (VT-x/AMD-V) is enabled on your hypervisor server. Catalyst 9000v - - EVE-NG consider these technical optimizations:

The term "best" in the search query often relates to performance. While the Cat9kv is a powerful tool, it is resource-intensive. To get the best performance out of your qcow2 images, consider these technical optimizations:
