Subject: [PATCH v3 2/6] docs/about/deprecated: Deprecate the qemu-system-i386 binary
Date: Fri, 3 Mar 2023 11:14:48 +0100 [thread overview]
Message-ID: <20230303101452.769367-3-thuth@redhat.com> (raw)
In-Reply-To: <20230303101452.769367-1-thuth@redhat.com>
Aside from not supporting KVM on 32-bit hosts, the qemu-system-x86_64
binary is a proper superset of the qemu-system-i386 binary. With the
32-bit host support being deprecated, it is now also possible to
deprecate the qemu-system-i386 binary.
With regards to 32-bit KVM support in the x86 Linux kernel,
the developers confirmed that they do not need a recent
qemu-system-i386 binary here:

+The ``qemu-system-i386`` binary was mainly useful for running with KVM
+on 32-bit x86 hosts, but most Linux distributions already removed their
+support for 32-bit x86 kernels, so hardly anybody still needs this. The
+``qemu-system-x86_64`` binary is a proper superset and can be used to
+run 32-bit guests by selecting a 32-bit CPU model, including KVM support
+on x86_64 hosts. Thus users are recommended to reconfigure their systems
+to use the ``qemu-system-x86_64`` binary instead.
