VMs & containers

VMs & containers lists every workload on every host: VMs, LXC containers, and Docker or Podman containers.

Find a workload

• Type in Filter by name, IP, OS… to narrow the list.
• Use the host and type filters to show one host, or only VMs or containers.
• The totals at the top show how many workloads are listed and the vCPU, RAM and disk they’re allocated.

Add a workload

1. Click + Add workload (or + Add workload on a host’s page, which pre-selects that host). You need at least one hypervisor host first.
2. Fill in:
   • Name, Type (virtual machine, LXC, Docker or Podman container) and Status (running, stopped, planned, decommissioned).
   • Hypervisor host and VMID / CTID / UUID.
   • vCPU, RAM (MB), Disk (GB) and Guest OS.
   • Network (from the IP address plan), and its IPv4 address and IPv6 address.
   • Notes.
3. Save.

Tip

On a Proxmox VE host you don’t need to type these in. Sync from Proxmox fills them in for you. See Hypervisor hosts.

Mark a workload as a simulation server

A VM or container that runs GNS3, EVE-NG, Cisco CML or Containerlab becomes a simulation server, with its own page under Simulation labs.

1. Edit the workload.
2. Set Platform to the simulator (leave it on — not a simulation server — for anything else).
3. Set Platform version. For GNS3 this decides how NetSimLab talks to it: 2.2.x or 3.1.0 and newer (e.g. 3.1.0a5) are supported.
4. Optionally add the Web UI URL, and tick Nested virtualization / VT-x passthrough enabled if the VM has it (simulators need it for fast QEMU nodes).
5. Save. The server now appears in the left-hand menu under Simulation labs.

Edit or delete

Use Edit on a workload’s row to change it. A simulation server can’t be deleted while it still has lab projects; move or delete those first.
