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_PV_SMP def_bool y depends on XEN_PV && SMP config XEN_PV_DOM0 def_bool y depends on XEN_PV && XEN_DOM0 config XEN_PVHVM def_bool y depends on XEN && X86_LOCAL_APIC config XEN_PVHVM_SMP def_bool y depends on XEN_PVHVM && SMP config XEN_PVHVM_GUEST bool "Xen PVHVM guest support" default y depends on XEN_PVHVM && PCI help Support running as a Xen PVHVM guest. config XEN_SAVE_RESTORE bool depends on XEN select HIBERNATE_CALLBACKS default y config XEN_DEBUG_FS bool "Enable Xen debug and tuning parameters in debugfs" depends on XEN && DEBUG_FS help Enable statistics output and various tuning options in debugfs.
