Use for config parity and protocol behavior – not for throughput benchmarking. Part 8: Automation & Management Enable NX-API for RESTCONF automation:

curl -k -u "admin:password" http://<vm-ip>/ins -d '"ins_api": "version":"1.0","type":"cli_show","cmd":"show version"' For Netmiko (Python): This is often due to memory starvation
grub> serial --unit=0 --speed=9600 grub> terminal_input serial grub> terminal_output serial Then boot normally. Or pre-set in EVE-NG: set serial console baud to 9600. This is often due to memory starvation . Increase VM RAM to at least 12 GB. Also disable KSM (Kernel Same-page Merging) if hypervisor is busy. Part 7: Performance Expectations & Realities Unlike physical Nexus 9000 (which uses the Cloud Scale ASIC), the virtual version is a pure software switch.
