Probably a 3.2.x- only fix. There is actually specific code in the 3.2 branch which checks for the presents of the variable being declared in the development environment: xen/arch/x86/hvm/vmx/vmx.c: else if ( v->arch.hvm_vmx.vmxassist_enabled ) xen/arch/x86/hvm/vmx/vmx.c:#else /* !defined(VMXASSIST) */ xen/arch/x86/hvm/vmx/Makefile:ifneq ($(vmxassist),y) xen/arch/x86/hvm/vmx/x86_64/exits.S:#ifndef VMXASSIST xen/arch/x86/hvm/vmx/x86_64/exits.S:#ifndef VMXASSIST xen/arch/x86/hvm/vpic.c:#ifdef VMXASSIST xen/arch/x86/hvm/vpic.c: current->arch.hvm_vmx.vmxassist_enabled; xen/arch/x86/x86_64/asm-offsets.c:#ifndef VMXASSIST This type of code doesn't exist in the 3.1. --------------------------------------- bash-3.2# strings /usr/pkg/libexec/qemu-dm|grep -i vmx (HVMXen) HVMXEN- bash-3.2# gzcat /xen.gz |strings |grep -i vmx vmx_intr_assist vmx_vmexit_handler vmx_do_invlpg vmx_set_cr0 vmx_world_restore vmx_io_instruction vmx_do_msr_read vmx_do_msr_write vmx_restore_guest_msrs vmx_vmcs_restore vmx.c VMXON failed VMX disabled by Feature Control MSR.
