Linux 5.4 Officially Deprecates Xen 32-bit PV Guest Support

As a late change that was merged yesterday for the Linux 5.4 kernel that will be released in the next few weeks, Xen 32-bit PV guest support has been deprecated.

SUSE’s Juergen Gross deprecation notice was accepted on Friday by Linus Torvalds for Linux 5.4. When configuring the kernel build with Xen para-virtualized support for x86 32-bit, the following warning will now be produced:

WARNING! WARNING! WARNING! WARNING! WARNING! WARNING! WARNING!
Support for running as 32-bit PV-guest under Xen will soon be removed
from the Linux kernel!
Please use either a 64-bit kernel or switch to HVM or PVH mode
WARNING! WARNING! WARNING! WARNING! WARNING! WARNING! WARNING!
