I see. But unfortunately this bit has multiple meanings for 64/32 bit, kvm does not know whether you will run a 32 bit or a 64 bit program. This is a cpu architecture bug.
Correct. One bit is used for two separate features (syscall-32 and syscall-64).
syscall-32 rarely matters because i386 guests use sysenter. It's only 32-on-64 guests that attempt to use syscall.
