The following are caveats for setting up OES 11 server in Xen VMs:
You should always close Virtual Machine Manager (VMM) when you are not actively using it. Virtual Machines are not affected.
Leaving VMM open can affect the system resources available to the VMs.
Time synchronization problems have been observed when virtualized NetWare servers are running the XNTPD NLM. Therefore, Novell strongly recommends using Timesync and also configuring the service to communicate through NTP.
When backing up a Xen virtual machine running virtualized NetWare, we recommend using a remote backup source rather than a local tape device because of limitations in detecting a local tape device.
Make sure you follow these guidelines for using NSS volumes in connection with OES servers running in Xen VMs:
OES: Data shredding is not supported.
