When you install OES on a virtual machine, we recommend that you configure a virtual machine with multiple devices. Use the primary disk on the guest server as the system device with LVM2 (the YaST install default) as the volume manager. After the install, assign additional storage resources from the host to the virtual machine. In this scenario, NSS volumes are created only on the data disks for the guest server, not on the system disk that you are using for the guest server’s system device.
IMPORTANT:When you create the virtual machine, make sure to configure the size of the primary virtual disk according to the amount of space you need for the boot (/boot), swap, and root (/) volumes.
