Your volume is now created, but still not useable on a virtual machine. You need to attach the volume to an already existing instance

A brief notice (in the top-left corner) will appear, mentioning the mount location on the virtual machine

The volume is now attached on the instance.
The following step is required for some Linux versions, and may differ between distributions.
Login to the instance on which the volume has been added.
The drive is (in my case, Centos 6) not visible and a forced scsi bus scan must be executed (as root!):
#> echo "- - -" > /sys/class/scsi_host/host0/scan
Now the volume is available as /dev/vdb on the server. Now just partition the drive (in this example used fdisk):
#> fdisk /dev/vdb and created a primary partition with all space used.

Now create a mount point for the drive, we will use /data
#> mkdir /data
Edit the /etc/fstab file, for automount after reboot. And just force a mount by:
#> mount -a

The volume is now available on your instance at the /data location
