There is no i386 PV support anymore:

|     x86/xen: remove 32-bit Xen PV guest support
|     
|     Xen is requiring 64-bit machines today and since Xen 4.14 it can be
|     built without 32-bit PV guest support. There is no need to carry the
|     burden of 32-bit PV guest support in the kernel any longer, as new
|     guests can be either HVM or PVH, or they can use a 64 bit kernel.
|     
|     Remove the 32-bit Xen PV support from the kernel.
