General Build Information (Linux DomU)

Linux Configurations Requirements

Linux needs to be built with the following options enabled:
These options are all enabled by default in PetaLinux projects. They can remain enabled without issue for native Linux systems running without Xen hypervisor.

CONFIG_XEN enables critical hooks for Xen interface from DomU
CONFIG_HVC_DRIVER includes a driver for the hypervisor (paravirtual) console within the guest. This avoids having to manually assign a dedicated serial console for use by the guest.

This Hypervisor console is an input/output console point to point between DomU and Dom0. It can be run over SSH, physical UART. When multiple DomU instantate a console, each is unique.
