This installation guide for the ExtremeCloud IQ Controller VE6120K and VE6125K Virtual Appliances on the KVM platform covers deployment requirements, VM configuration procedures, initial appliance setup, software upgrade, backup management, USB flash drive integration, licensing, bridge configuration, and VM lifecycle management. The appliances are distributed as compressed raw disk images and must be deployed on a KVM server host; VE6120K and VE6125K use separate images and are not interchangeable. Deployment procedures are provided for both a generic KVM approach and Proxmox Virtual Environment (Proxmox VE), covering VM creation parameters including CPU, memory, disk, and network interface configuration. Scale options range from Small (50 APs, 4 cores, 8 GB RAM) to XLarge (2000 APs, 20 cores, 32 GB RAM), with high-availability pair configurations supporting up to 4000 APs and 32,000 simultaneous users. Initial configuration is performed via the CLI-based Basic Configuration Wizard, which steps through admin password setup, data port settings, host attributes, default gateway, and NTP configuration. Data plane bridges must support promiscuous mode and unmodified VLAN tag forwarding; jumbo frame support requires setting MTU to 1800 bytes on both the network device and attached Linux bridge. USB flash drives, formatted as FAT32, can be attached to both shutdown and operational VMs for backup, restore, upgrade, and log collection. Licensing uses a subscription model tied to managed AP count, with an Activation Package generated from the Extreme Support Portal using a system Locking ID.
