There is a #VE exception defined in p2086 of Intel Software Development Manual, however, no definition of exception handler is availble in Xen 4.6. <http://xenbits.xen.org/gitweb/?p=xen.git;a=blob;f=xen/arch/x86/x86_64/entry.S;h=d0f3259efe8b63a152fb413696b66cfb6a382345;hb=9772c480a71ad38cc2c342e4c2e78c2475de7268#l658>Should I define the handler by myself by modifying the source code of xen, or is there a way to define the handler of the reserved IDT vectors (0-31, #VE is 20) without modifying the source code?
