Planning For Netware Vm Guest Servers - Novell OPEN ENTERPRISE SERVER 2 SP2 Installation Manual

To ensure that optimal resources are available to the virtual machines, each VM host server should
be dedicated to running the Xen virtualization software as much as possible. However, there are
several good reasons why you might want to choose to install one or more of the supported OES
services on the host server itself. For more information, see

11.3.2 Planning for NetWare VM Guest Servers

Before creating NetWare virtual machines, you need to plan for the following:
"RAM Planning" on page 194
"Storage Planning" on page 194
"Network Planning" on page 194
"eDirectory Planning" on page 195
RAM Planning
To ensure the best performance by your NetWare VM guests, you should plan for the optimal RAM
configuration of each NetWare VM guest server. As a general rule, the more RAM you assign to a
NetWare guest server (up to 8 GB), the better the server performance is. For specific planning
information, see
Guide.
Storage Planning
The disk space that you allocate while creating the Xen virtual machines is used by the NetWare
VM guest for the
For best performance in a Xen virtual environment, NSS pools and volumes on NetWare should be
created on virtual devices that are SCSI devices, Fibre Channel devices, or iSCSI devices on the host
server, or on partitions that are on those types of devices.
SATA or IDE disks have slower performance because special handling is required when working
through the Xen driver to ensure that data writes are commited to the disk in the order intended
before the driver reports back.
For more information on NSS disk storage, see
OES 2 SP2: NSS File System Administration
Network Planning
Each Xen guest VM is assigned one virtualized network card by default. You can create additional
cards if desired.
You must obtain one static IP address for each virtualized network card you plan to create on your
NetWare VM guest servers. OES 2 SP2 does not support dynamically assigned (DHCP) IP
addresses.
