Maintaining the 32-bit x86 port, and implementing new features for it, is an ongoing development burden which could be more usefully directed elsewhere. Therefore, 32-bit x86 will be considered obsolete in the 4.3 development branch, and removed. 32-bit x86 will continue to be maintained and supported (insofar as it has been recently) in the supported stable branches: 3.4, 4.1, and 4.2. Furthermore, 32-bit guests (including 32-bit PV guests) will continue to be supported on the 64-bit hypervisor, as they always have been. Regards, Keir & The Xen Team
