[one-users] lvm, configure oneimage

[haseningo at gmx.de]

Hi everybody,

my configuration:

1 iscsi device which has a LVM on top. over the nodes I have configured clvm. everything is fine, if I created a new lvm-device, every node can access this new image. 
now I want to configure my existing blockdevices to my virtual machines. 
For example my blockdevice is this:

/dev/one_vm/windowstest (ACTIVE '/dev/one_vm/windowstest' [40.00 GiB] inherit)

How can I configure opennebula (oneimage) to use this device? I configured the lvm-driver in oned.conf and changed the default lvm name in opennebula. New lvm-blockdevices will created by opennebula in my lvm-cluster, great. But how can I use existing devices?

The symlink is not correct.
