Alexandre Derumier 04a69bb4fe add template_create
qm template <vmid> [-disk virtio0]

convert a full vm to a template (or only a disk if specify)

we orignal disk to /base (file) or base- (lvm,rbd,sheepdog,nexenta)
we create a snapshot @base if storage need it for clone
we protect the volume or snapshot

=head1 NAME
qm - qemu/kvm virtual machine manager
=head1 SYNOPSIS
=include synopsis
=head1 DESCRIPTION
qm is a script to manage virtual machines with qemu/kvm. You can
create and destroy virtual machines, and control execution
(start/stop/suspend/resume). Besides that, you can use qm to set
parameters in the associated config file. It is also possible to
create and delete virtual disks.
=head1 CONFIGURATION
All configuration files consists of lines in the form
PARAMETER: value
See L<vm.conf|vm.conf> for a complete list of options.
Configuration files are stored inside the Proxmox configuration file system, and can be access at F</etc/pve/qemu-server/C<VMID>.conf>.
The default for option 'keyboard' is read from
F</etc/pve/datacenter.conf>.
=head1 Locks
Online migration and backups (vzdump) set a lock to prevent
unintentional action on such VMs. Sometimes you need remove such lock
manually (power failure).
qm unlock <vmid>
=head1 EXAMPLES
# create a new VM with 4 GB ide disk
qm create 300 -ide0 4 -net0 e1000 -cdrom proxmox-mailgateway_2.1.iso
# start the new VM
qm start 300
# send shutdown, then wait until VM is stopped
qm shutdown 300 && qm wait 300
# same as above, but only wait for 40 seconds
qm shutdown 300 && qm wait 300 -timeout 40
