FAQ

Do I need vendor images?
For Cisco / Juniper / Fortinet / Palo Alto / similar QEMU labs: yes, you supply disks you are entitled to use. FOSS Docker FRR/Alpine starters work without vendor images.
OVA or USB?
Use OVA on VMware. Use USB bare metal when you need native KVM for heavy nested guests. Software day-1 is the same.
Why is nested VT-x required?
QEMU labs need /dev/kvm. Inside VMware that means the host must not hold Hyper-V on top of Workstation, and the VM must expose VT-x.
What do Certified, Verified, and Experimental mean?
Images -> Compatibility shows only these three chips:
- Certified - full VEX-NX verification suite passed (boot, wipe, snapshot, clone, export/import, console path, ...). It does not mean automated guest login.
- Verified - partial / smoke verification; not the full Certified bar.
- Experimental - early support; expect tweaks.
List and details: Catalog and Compatibility.
Why does Compatibility still say Experimental for my disk?
Status is per template, not per your file. Importing a disk does not upgrade Experimental (or Verified) to Certified.
FRR Start says image not found
Run sudo vexnx-seed-docker. Fix DNS if pulls fail. Current OVA/ISO should include offline tarballs.
SecureCRT will not open
Install the Console Helper; allow port 8022; node must be running. HTML5 Terminal always works as fallback.
Student vs Enterprise
Student is free and builtin: core labs, packet capture, running-config and lab bundle import, Assist, and the MCP agent API, capped at 5 concurrent labs / 100 nodes per lab / 1 user with the community template allow-list.
Enterprise needs a signed licence file and adds classroom timers, LDAP / SSO / RADIUS, and unlimited labs, nodes, and users. Student already includes the full template catalog. Pro, Academic, Team, and Trial are retired. See Features.
Where is the Admin Guide?
