Converting LVM virtual machine storage to image

To convert the LVM disk to qcow2 formatted disk image,

Use lvdisplay to get the Logical volume name

$ sudo lvdisplay

Use qemu-img to convert to the required image format

# qemu-img convert -O qcow2 /dev/mapper/lv_name .qcow2

eg:

# qemu-img convert -O qcow2 /dev/mapper/disk1 disk1.qcow2

This will be useful to replicate the virtual machines to other hardware.
