My Xeon CPU spports lots of capabilities, when I cat /proc/cpuinfo, the flags 
list: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 
clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm constant_tsc pni monitor 
ds_cpl vmx est tm2 ssse3 cx16 xtpr dca lahf_lm.

After a make world building of Xen-3.3.0, when I cat /proc/cpuinfo, the flags 
list only: fpu de tsc msr pae cx8 apic mtrr cmov pat clflush acpi mmx fxsr sse 
sse2 ss ht nx constant_tsc pni est.

I am only able to make world the dom0 kernel, as I don't know how to configure 
the kernel. Last time I make oldconfig, but it eventually failed.
Can anyone help? I want to add at least the "vmx" CPU capability to dom0 kernel.
