Thanks. I am not sure whether it fits in "Items not limited to the
upgrade process" or under "Obsolescence and deprecation", but how
about:
The Linux kernel no longer provides support for 32-bit Xen
guests in PV mode.
Users of 32-bit Xen guests should check that they are running in
either PVH or HVM mode before upgrading to bullseye, since as of
v5.9 the Linux kernel will not boot as a 32-bit Xen PV mode
guest.
You can check which type of Xen guest you are running as
follows:
<pre>
$ cat /sys/hypervisor/guest_type
PV
</pre>
If you see <b>PVH</b> or <b>HVM</b> here then you should be safe
to upgrade to bullseye.
If it is a requirement to continue using PV mode, the least
disruptive option may be to <a
href="https://wiki.debian.org/CrossGrading";>switch to an amd64
(64-bit) kernel</a>. It is not necessary to cross-grade the
entire system to amd64.
Not sure if the last paragraph is appropriate as I'm not sure if
cross-grading like that is considered supported, even though I
suppose multiarch is considered supported, so why not?
Anyway, all of this is only for the i386 release notes as amd64
support has not been dropped.
Thanks!
Andy
