Rollback to snapshot$ qm rollback vm_id snap_name
SYNOPSIS
qm snapshot [OPTIONS] vmid snapname
DESCRIPTION
qm snapshot creates a point-in-time snapshot of a QEMU/KVM virtual machine in Proxmox VE. Snapshots capture the disk state and optionally the VM memory state, allowing rollback to that point later.
PARAMETERS
vmid
The numeric ID of the virtual machinesnapname
Name for the snapshot (must start with a letter)--description text
Description text for the snapshot--vmstate boolean
Include the VM memory state in the snapshot
CAVEATS
Snapshot names must start with a letter. Including vmstate allows restoring the running state but requires more storage. Snapshots use copy-on-write, so disk space usage grows as changes accumulate.
HISTORY
qm snapshot is part of the Proxmox VE virtualization platform for managing QEMU/KVM virtual machine snapshots.
