When you install OES 2018 or later on a virtual machine, we recommend that you configure a virtual machine with multiple devices. Use the primary virtual disk as the system device with LVM (the YaST install default) as the volume manager. After the install, you can assign additional storage resources from the host server to the virtual machine.
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, swap, and root (/) volumes.
After the virtual machine is set up, you need to perform additional tasks to set up additional Novell Storage Service (NSS) devices. See OES 2018 SP2: NSS File System Administration Guide for Linux.
