General Build Information (Linux DomU)
Linux Configurations RequirementsLinux needs to be built with the following options enabled:
CONFIG_XEN CONFIG_HVC_DRIVER CONFIG_HVC_XEN
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.
