XenVM devices
When a XenVM is created, not only the main memory and CPUs are configured, but also
virtual devices. From the viewpoint of the guest system (Linux/Windows), these devices
look like real devices. To enable the guest system to recognize and use the devices
configured on the XenVM, the corresponding device drivers must be installed in the guest
system.
