Virtualization Architecture and strategies
64 U41855-J-Z125-3-76
A XenVM can be assigned installation sources; the Linux/Windows systems see these as
(virtual) drives. This assignment takes place either when the XenVM is created or at a later
point in time, i.e. during ongoing operation.
For information on tasks in the XenVM device management see section “Managing
installation sources” on page 195.
Virtual switches
The Linux/Windows systems on the XenVMs communicate with each other or with external
systems via software instances which are known as virtual switches (or vSwitches for
short).
Tape drives
Tape drives cannot be operated on XenVMs. Data backup of the Linux/Windows systems
can be implemented via the IP network, e.g. by means of a Networker backup using an
external backup server.
