Installing and Managing NetWare on a Xen-based VM 195novdocx (en) 7 January 2010eDirectory PlanningYou can place a NetWare virtual machine in an existing tree or as the first server in a new tree.However, the performance of virtualized NetWare doesn’t match a physical NetWare installation. Inmost cases, it is probably preferable to add your NetWare virtual machine to an existing tree locatedon a physical NetWare server, particularly if the tree is large.Also, because virtualized servers might be started and stopped more often than they would normallybe on physical servers, we recommend that the master replica (usually the first server in a tree) beplaced on a system that is running at all times. For more information about master replicas, see“Managing Partitions and Replicas” in the Novell eDirectory 8.8 Administration Guide.11.3.3 You Must Use Timesync for Time SynchronizationBecause of known issues with Xen and the NTP NLM, you must use Timesync as the timesynchronization method for NetWare VM guests running on Xen VM hosts. Otherwise, time driftcauses problems for your NetWare VM guests.Keeping accurate time is a critical function for servers in an eDirectoryTM tree. The reported timemust be synchronized across the network to provide the expiration dates and time stamps necessaryfor ordering eDirectory events.NetWare VM guest servers synchronize time in the same ways that NetWare physical servers do. Inother words, the clock on the VM host server has no influence on the NetWare VM guest server’stime.IMPORTANT: To ensure that your NetWare VM guest is configured correctly, be sure to followthe instructions in “Configuring Time Synchronization” (specifically Step 4) in the NW65 SP8:Installation Guide, and configure the NetWare VM guest to get time from the same time source asthe eDirectory tree it is joining. If the time source specified is an NTP server, be sure to select theNTP option next to the source’s DNS name or IP address. This enables Timesync to communicatewith the NTP time source.11.3.4 Disabling the Alt+Esc Shortcut on the HostAlt+Esc is used on a NetWare server to switch between console screens, but on SLES 10 it movesbetween open windows. To provide the expected behavior for the virtualized NetWare server, youmust disable the shortcut for SLES 10.1 On the host server as the root user, click Computer > Control Center.2 Click Personal > Shortcuts.3 Under the Window Management category, click Move between windows immediately, thenpress the Backspace key to disable the shortcut.4 Click Close.5 Close the Control Center.11.4 Installing Virtualized NetWareThis section provides the instructions for installing NetWare 6.5 SP8 as a guest OS.
