Proxmox VE virtualization platform reference for VM management, containers, clustering, and homelab infrastructure.
Quick Reference
# VM management (qm)
qm list # List all VMs
qm status <vmid> # Check VM status
qm start <vmid> # Start VM
qm stop <vmid> # Stop VM (graceful)
qm shutdown <vmid> # Shutdown VM (ACPI)
qm unlock <vmid> # Remove lock
qm config <vmid> # Show VM config
# Container management (pct)
pct list # List all containers
pct status <ctid> # Check container status
pct start <ctid> # Start container
pct stop <ctid> # Stop container
pct enter <ctid> # Enter container shell
# Cluster management (pvecm)
pvecm status # Cluster status and quorum
pvecm nodes # List cluster nodes
# API shell (pvesh)
pvesh get /nodes # List nodes via API
pvesh get /nodes/<node>/status # Node resource status
# Backup (vzdump)
vzdump <vmid> --mode snapshot --storage <storage>
vzdump --all --compress zstd
