To create an OES VM guest, you need a SLES 15 SP3 or later server that is set up as a VM host server.
When you set up a virtual machine host for OES VM guests, ensure that the host server has the following:
Time synchronization: Set the server’s time configuration to the same reliable, external time source as the eDirectory tree that the virtual machines on that host will be joining.
To set the time source, use Yast > NTP Configuration.
The time source can be running NTP or Timesync with the NTP option selected.
RAM: Enough memory to support each virtual machine that you want to run concurrently on the host server.
For example, if you are installing one OES virtual machine, you need a minimum of 2 GB of memory (1 GB for the host plus 1GB for the OES Linux VM).
If you are installing two virtual machines, and the first VM guest’s services need 1 GB and the second guest’s need 1.5 GB, you need 2.5 GB for the VM guests and 1 GB for the host—a total of 3.5 GB.
Disk Space: Enough disk space on the host for creating and running your VM guests.
The default disk space required for an OES VM guest is 7 GB and the default allocation for each VM guest in Xen is 10 GB, leaving only approximately 6 GB for data files, etc. The space you need is dependent on what you plan to use the virtual server for and what other virtual storage devices, such as NSS volumes, that you plan to attach to it.
SLES Platform: OES 2018 or later VM is tested as guest on SLES 15 SP3 or later VM hosts.
If you want to set up Novell Storage Services (NSS) on the virtual machine, note the following:
NSS can recognize physical, logical, or virtual devices.
For information, see Device Size
in the Storage Services File System (NSS) Administration Guide for Linux.
For setup procedures, see the Virtualization Guide.
