But the user could be reading the release notes form perspective of the host, which could be running any arch, so i think safer to include in every arch's release-notes <section id="32bit-xen-pv-guest-not-supported"> <title>32-bit Xen PV guests are not supported</section> <para> The Linux kernel (from version 5.9) not longer support 32-bit <systemitem role="package">xen</systemitem> virtual machines using <ulink url="https://wiki.xenproject.org/wiki/Virtualization_Spectrum">PV mode</ulink>. Such virtual machines need to be converted to the 64-bit amd64 architecture (see <xref linkwns="reference the bit about i386 support"/>). </para> <para> You can check which mode a Xen guest is running (inside the virtual machine): <commandlisting> $ cat /sys/hypervisor/guest_type PV </commandlisting> Virtual machines that return, for example, <literal>PVH</literal> or <literal>HVM</literal> are not affected. <!-- other options also possible --> </para> </section>
