Lvm und virtualbox

First, I created the lvm volume

lvcreate --name www --size 10G images

Next, I created a vmdk file which describes the disk properties using the VBoxManage command:

VBoxManage internalcommands createrawvmdk -filename /vbox/www.vmdk -rawdisk /dev/images/www

Here are the contents of the vmdk file after running that command:

# Disk DescriptorFile
version=1
CID=e5ee218c
parentCID=ffffffff
createType="fullDevice"

# Extent description
RW 20971520 FLAT "/dev/images/www" 0 

# The disk Data Base
#DDB

ddb.virtualHWVersion = "4"
