391 qm - qemu/kvm virtual machine manager
399 qm is a script to manage virtual machines with qemu/kvm. You can
400 create and destroy virtual machines, and control execution
401 (start/stop/suspend/resume). Besides that, you can use qm to set
402 parameters in the associated config file. It is also possible to
403 create and delete virtual disks.
407 All configuration files consists of lines in the form
411 See L<vm.conf|vm.conf> for a complete list of options.
413 Configuration files are stored inside the Proxmox configuration file system, and can be access at F</etc/pve/qemu-server/C<VMID>.conf>.
415 The default for option 'keyboard' is read from
416 F</etc/pve/datacenter.conf>.
420 Online migration and backups (vzdump) set a lock to prevent
421 unintentional action on such VMs. Sometimes you need remove such lock
422 manually (power failure).
428 # create a new VM with 4 GB ide disk
429 qm create 300 -ide0 4 -net0 e1000 -cdrom proxmox-mailgateway_2.1.iso
434 # send shutdown, then wait until VM is stopped
435 qm shutdown 300 && qm wait 300
437 # same as above, but only wait for 40 seconds
438 qm shutdown 300 && qm wait 300 -timeout 40
