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
       --print-xml
         Print the generated clone XML and exit without cloning.

       --replace
         Shutdown and remove any existing guest with the passed "--name" before cloning the
         original guest.

       -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
