	  This is the Linux Xen port.  Enabling this will allow the

	  Xen hypervisor.

config XEN_512GB
	bool "Limit Xen pv-domain memory to 512GB"
	depends on XEN_PV && X86_64
	default y
	help
	  Limit paravirtualized user domains to 512GB of RAM.

The Xen tools and crash dump analysis tools might not support
	  pv-domains with more than 512 GB of RAM. This option controls the
	  default setting of the kernel to use only up to 512 GB or more.
	  It is always possible to change the default via specifying the
	  boot parameter "xen_512gb_limit".

config XEN_SAVE_RESTORE
       bool
       depends on XEN

config XEN_DEBUG_FS
	bool "Enable Xen debug and tuning parameters in debugfs"
	depends on XEN && DEBUG_FS
	default n
	help
	  Enable statistics output and various tuning options in debugfs.
	  Enabling this option may incur a significant performance overhead.
