In the Xen x86 community call we have been discussing whether anyone
really is depending on 32-bit PV guests. We'd like to evaluate whether
anyone would see problems with:
- deprecating 32-bit PV guest support in Xen, meaning that we'd
eventually switch to support 32-bit PV guests only via PV-shim from
Xen 4.12 or 4.13
- dropping 32-bit PV support from upstream Linux kernel, resulting in
current 32-bit PV guests no longer being able to upgrade to the newest
kernel version any longer
And related to that:
- is there any Linux distribution still shipping 32-bit PV-capable
systems?
- what about BSD? Is 32-bit PV support important there?
Juergen
