CONFIG_XEN: Xen guest support

General informations

The Linux kernel configuration item CONFIG_XEN has multiple definitions:

Enable support for Xen hypervisor found in arch/i386/xen/Kconfig

The configuration item CONFIG_XEN:

• prompt: Enable support for Xen hypervisor
• type: bool
• depends on: CONFIG_PARAVIRT && CONFIG_X86_CMPXCHG && CONFIG_X86_TSC && ! CONFIG_NEED_MULTIPLE_NODES
• defined in arch/i386/xen/Kconfig
• found in Linux kernels: 2.6.23

Help text

This is the Linux Xen port. Enabling this will allow the kernel to boot in a paravirtualized environment under the Xen hypervisor.

Xen guest support on ARM (EXPERIMENTAL) found in arch/arm/Kconfig

The configuration item CONFIG_XEN:

• prompt: Xen guest support on ARM (EXPERIMENTAL)
• type: bool
• depends on: ( CONFIG_ARM && CONFIG_AEABI && CONFIG_OF ) && ( CONFIG_CPU_V7 && ! CONFIG_CPU_V6 ) && (! CONFIG_GENERIC_ATOMIC64 )
• defined in arch/arm/Kconfig
• found in Linux kernels: 3.7–3.9, 3.10-rc+HEAD

Help text

Say Y if you want to run Linux in a Virtual Machine on Xen on ARM.

Xen guest support found in arch/x86/xen/Kconfig

The configuration item CONFIG_XEN:

• prompt: Xen guest support
• type: bool
• depends on: ( CONFIG_PARAVIRT ) && ( CONFIG_X86_64 || ( CONFIG_X86_32 && CONFIG_X86_PAE && ! CONFIG_X86_VISWS )) && ( CONFIG_X86_TSC )
• defined in arch/x86/xen/Kconfig
• found in Linux kernels: 2.6.24–2.6.39, 3.0–3.9, 3.10-rc+HEAD

This is the Linux Xen port. Enabling this will allow the kernel to boot in a paravirtualized environment under the Xen hypervisor.

Xen hypervisor support found in arch/ia64/xen/Kconfig

The configuration item CONFIG_XEN:

• prompt: Xen hypervisor support
• type: bool
• depends on: CONFIG_PARAVIRT && CONFIG_MCKINLEY && CONFIG_IA64_PAGE_SIZE_16KB
• defined in arch/ia64/xen/Kconfig
• found in Linux kernels: 2.6.28–2.6.39, 3.0–3.9, 3.10-rc+HEAD

Help text

Enable Xen hypervisor support. Resulting kernel runs both as a guest OS on Xen and natively on hardware.
