NAME

       virt-clone - clone existing virtual machine images

SYNOPSIS

       virt-clone [OPTION]...

DESCRIPTION

       virt-clone is a command line tool for cloning existing virtual machine images using the "libvirt" hypervisor management library. It will
       copy the disk images of any existing virtual machine, and define a new guest with an identical virtual hardware configuration. Elements
       which require uniqueness will be updated to avoid a clash between old and new guests.

       By default, virt-clone will show an error if the necessary information to clone the guest is not provided. The --auto-clone option will
       generate all needed input, aside from the source guest to clone. An interactive mode is available with the --prompt option, but this will
       only ask for the minimum required options.

OPTIONS

       Most options are not required. Minimum requirements are --original or --original-xml (to specify the guest to clone), --name, and
       appropriate storage options via -file.

       -h, --help
	   Show the help message and exit

       --connect=CONNECT
	   Connect to a non-default hypervisor. See virt-install(1) for details

   General Options
       General configuration parameters that apply to all guest clones.

       -o ORIGINAL_GUEST, --original=ORIGINAL_GUEST
	 Name of the original guest to be cloned. This guest must be shut off or paused since it is not possible to safely clone active guests at
	 this time.

       --original-xml=ORIGINAL_XML
	 Libvirt guest xml file to use as the original guest. The guest does not need to be defined on the libvirt connection. This takes the
	 place of the "--original" parameter.

       --auto-clone
	 Generate a new guest name, and paths for new storage.

	 An example or possible generated output:

	   Original name	: MyVM
	   Generated clone name : MyVM-clone

	   Original disk path	: /home/user/foobar.img
	   Generated disk path	: /home/user/foobar-clone.img

	 If generated names collide with existing VMs or storage, a number is appended, such as foobar-clone-1.img, or MyVM-clone-3.

       -n NAME, --name=NAME
	 Name of the new guest virtual machine instance. This must be unique amongst all guests known to the hypervisor connection, including
	 those not currently active.

       -u UUID, --uuid=UUID
	 UUID for the guest; if none is given a random UUID will be generated. If you specify UUID, you should use a 32-digit hexadecimal number.
	 UUID are intended to be unique across the entire data center, and indeed world. Bear this in mind if manually specifying a UUID

   Storage Configuration
       -f DISKFILE, --file=DISKFILE
	 Path to the file, disk partition, or logical volume to use as the backing store for the new guest's virtual disk. If the original guest
	 has multiple disks, this parameter must be repeated multiple times, once per disk in the original virtual machine.

       --force-copy=TARGET
	 Force cloning the passed disk target ('hdc', 'sda', etc.). By default, "virt-clone" will skip certain disks, such as those marked
	 'readonly' or 'shareable'.

       --nonsparse
	 Fully allocate the new storage if the path being cloned is a sparse file.  See virt-install(1) for more details on sparse vs. nonsparse.

       --preserve-data
	 No storage is cloned: disk images specific by --file are preserved as is, and referenced in the new clone XML. This is useful if you want
	 to clone a VM XML template, but not the storage contents.

   Networking Configuration
       -m MAC, --mac=MAC
	 Fixed MAC address for the guest; If this parameter is omitted, or the value "RANDOM" is specified a suitable address will be randomly
	 generated. Addresses are applied sequentially to the networks as they are listed in the original guest XML.

   Miscellaneous Options
       -d, --debug
	 Print debugging information to the terminal when running the install process.	The debugging information is also stored in
	 "$HOME/.virtinst/virt-clone.log" even if this parameter is omitted.

       --force
	 Prevent interactive prompts. If the intended prompt was a yes/no prompt, always say yes. For any other prompts, the application will
	 exit.

       --prompt
	 Specifically enable prompting for required information. Default prompting is off.

EXAMPLES

       Clone the guest called "demo" on the default connection, auto generating a new name and disk clone path.

	 # virt-clone 
	      --original demo 
	      --auto-clone

       Clone the guest called "demo" which has a single disk to copy

	 # virt-clone 
	      --original demo 
	      --name newdemo 
	      --file /var/lib/xen/images/newdemo.img

       Clone a QEMU guest with multiple disks

	 # virt-clone 
	      --connect qemu:///system 
	      --original demo 
	      --name newdemo 
	      --file /var/lib/xen/images/newdemo.img 
	      --file /var/lib/xen/images/newdata.img

       Clone a guest to a physical device which is at least as big as the original guests disks. If the destination device is bigger, the new
       guest can do a filesystem resize when it boots.

	 # virt-clone 
	      --connect qemu:///system 
	      --name demo 
	      --file /dev/HostVG/DemoVM 
	      --mac 52:54:00:34:11:54
