: At least 16 GB to 24 GB of RAM per switch instance GNS3.

This behavior is false-positive. Customers reported that they monitored the chassis and found no actual overheating, yet the switch would still reload due to a thermal violation sensor reading. This is tracked under Cisco Bug ID and affects several IOS-XE versions. If you see "hot" in the context of a log, this is likely the culprit. The bug causes major network disruption, requiring a hard reboot even though the hardware is fine. cat9kvprd171201prd9qcow2 hot

Deploying the cat9kv-prd-17.12.01prd9.qcow2 image requires a massive amount of physical server hardware resources compared to older legacy images. This is tracked under Cisco Bug ID and

If the virtual switch drops console connectivity or exhibits 100% CPU spikes during a hot file activation, ensure that your hypervisor node is not overselling RAM. The Cat9kv demands up to 24GB of physical RAM allocated to a single node to successfully unpack and map new runtimes into memory.
