10.1.1 OES 2 SP2 VM Host Considerations

When you set up a virtual machine host for OES 2 SP2 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
To set the time source, use Yast > Network Services > NTP Time Configuration.
The time source can be running NTP or Timesync.
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 2 SP2 virtual machine, you need a minimum of
1 GB of memory (512 MB for the host plus 512 MB for the OES 2 Linux VM).
If you are installing two virtual machines, and the first VM guest's services need 1 GB
while the second guest's need 1.5 GB, you need 2.5 GB for the VM guests and 512 MB
for the host—a total of 3 GB.
Disk Space: Enough disk space on the host for creating and running your VM guests.
The default disk space required for an OES 2 SP2 VM guest is 4 GB and the default
allocation for each VM guest in Xen is 10 GB, leaving 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.

10.1.2 Novell Storage Services Considerations

If you want to set up Novell Storage Services
NSS can recognize physical, logical, or virtual devices up to 2 TB in size (where 1 TB = 2E40
bytes = 1,099,511,627,776 bytes).
In a virtual environment, the devices that you want to use for the NSS file system on the guest
operating system cannot exceed the 2 TB limit, even if the host operating system and guest
operating system can handle larger devices.

Guide.

10.1.3 Setup Instructions

As mentioned in
page 177, you can use either a SLES 10 SP3 server or an OES 2 SP2 server as your VM host server.
For setup procedures, see
