A few questions to help us all first:-
  • Where do you get your storage for the VM from?
  • What did you allocate it the VM?
  • What can you see with the fdisk command?
  • Are you using LVM?
  • Do you have multiple volume groups, or is it all just one big one?
There may be more questions to follow.


Sorry about that,
Robin

NAME
virt-clone - clone virtual machine images SYNOPSIS
/usr/bin/virt-clone [option] DESCRIPTION
The virt-clone utility is a command line tool for cloning existing virtual machine images. virt-clone copies disk images of an existing virtual machine and defines a new guest with an identical virtual hardware configuration. Elements that require uniqueness are updated to avoid a clash between old and new guests. With appropriate command-line arguments, virt-clone can run completely unattended, with the guest automatically starting itself as well. This allows for easy automation of guest installs. If you do not specify options to virt-clone, the command runs interactively, prompting for input as required. To run virt-clone, you must become superuser or assume the Primary Administrator role. OPTIONS
The following options are supported: --connect=URI Connect to the hypervisor at URI. -d, --debug Display debugging information when running the install process. -f disk_image, --file=disk_image Path to the file, disk partition, or logical volume to use as the backing store for the 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. -h, --help Display the help message and exit. -m mac_addr, --mac=mac_addr Fixed MAC address for the guest. If the keyword random is specified, a random address will be used. -n name, --name=name Name of the new guest virtual machine instance. This must be unique among all guests known to the hypervisor on this machine, including those not currently active. To redefine an existing guest, use the virsh(1M) tool to shut it down and delete it prior to running virt- clone. This parameter will be prompted for if omitted on the command line. -o original_guest, -original=original_guest Name or UUID for the original guest to be cloned. This guest must be shut down since it is not possible to safely clone active guests. -u UUID, -uuid=UUID UUID for the guest; if none is specified, a random UUID is generated. If you specify UUID, use a 32-digit hexadecimal number. Keep in mind that UUIDs are intended to be unique across the entire data center, and indeed, the world. EXAMPLES
Example 1 Cloning a Guest with a Single Disk The following command clones a guest named demo, which has a single disk to copy. # virt-clone --original demo --name newdemo --file /var/lib/xen/images/newdemo.img Example 2 Cloning a Guest with Multiple Disks The following command clones a guest named demo, with has multiple disks to copy. # virt-clone --original demo --name newdemo --file /var/lib/xen/images/newdemo.img --file /var/lib/xen/images/newdata.img Example 3 Cloning to a Device with Comparable Disk Space The following command clones a guest to a physical device that has at least as much disk space as had the original guest. . If the destina- tion device is has more space, the new guest can do a file system resize when it boots. # virt-clone --name demo --file /dev/HostVG/DemoVM --mac 00:16:3e:34:11:54 ATTRIBUTES
