424 qm - qemu/kvm virtual machine manager
432 qm is a script to manage virtual machines with qemu/kvm. You can
433 create and destroy virtual machines, and control execution
434 (start/stop/suspend/resume). Besides that, you can use qm to set
435 parameters in the associated config file. It is also possible to
436 create and delete virtual disks.
440 All configuration files consists of lines in the form
444 See L<vm.conf|vm.conf> for a complete list of options.
446 Configuration files are stored inside the Proxmox configuration file system, and can be access at F</etc/pve/qemu-server/C<VMID>.conf>.
448 The default for option 'keyboard' is read from
449 F</etc/pve/datacenter.conf>.
453 Online migration and backups (vzdump) set a lock to prevent
454 unintentional action on such VMs. Sometimes you need remove such lock
455 manually (power failure).
