FAQ — Frequently Asked Questions
What is the difference between VMs (QEMU/KVM) and LXC Containers?
Each group in this Proxmox VE CLI cheat sheet covers a distinct area. VMs (QEMU/KVM) focuses on its specific scope, while LXC Containers and the remaining groups cover networking, storage, security and diagnostics respectively.
How do I check the installed Proxmox VE CLI version?
Run the version command (usually qm version or qm --version). The output shows the client and, when applicable, the server version.
Why does Proxmox VE CLI return ‘permission denied’?
A ‘permission denied’ error in Proxmox VE CLI usually means the current user lacks sufficient privileges or credentials are not configured. Check: (1) assigned IAM/RBAC roles, (2) an active authentication context via the corresponding login command.
How do I filter Proxmox VE CLI output by status or name?
Use flags such as --filter, --selector or --query depending on the tool. You can also pipe into grep or jq to process JSON:
qm list | grep RUNNING
What is the fastest way to debug a Proxmox VE CLI error?
Add the verbose flag (--verbose, -v or --debug) to the failing command. This reveals the underlying HTTP/API calls and the full error response body.
