Step 1 : convert image in "raw" format. qemu-img convert -f vmdk original_image.vmdk -O raw xen_compatible.img VMDK or another format like QCOW, QCOW2 ... Step 2 : create your LVM partition Make it bigger than "xen_compatible.img" ! Step 3 : copy the data "dd" is your friend dd if=xen_compatible.img of=/dev/your_lvm_partition bs=32k Step 4 : resize the FS Mount the partition on another machine (could be another VM) and "resize" the filesystem to "fill" the LVM partition. (It is not possible to do a "live" filesystem resize ). Step 5 : all should be OK link the new filesystem to your VM instead of the "old" image file and try to start your VM The process is safe as your original image is not destroyed, you can wait a little before scratching it. PS: I never use image files, LVM is easier to adapt to the needs.
