A reminder for those upgrading 32-bit Debian guests

Hi, A reminder that if you have a 32-bit Debian guest that you are keeping up to date: The Linux kernel removed support for 32-bit PV guests at version 5.9, so it will not be possible for you to upgrade from Debian 10 (buster) to 11 (bullseye) without taking action. This was mentioned before, but since then there have been a few casualties anyway (seemingly-unbootable guests). https://lists.bitfolk.com/lurker/message/20210930.104643.2ab5f9c0.en.html As you can see, as long as you are running a kernel above 4.19.0 and are using grub-pc to boot, you can just switch to PVH mode. This isn't an issue for Ubuntu because no 32-bit support there at all for some time, nor for CentOS because no upgrades between major releases there either.
