[PATCH 1/2] docs/about: Deprecate 32-bit x86 hosts and qemu-system-i386

Hardly anybody still uses 32-bit x86 hosts today, so we should start deprecating them to finally have less test efforts. 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: https://lore.kernel.org/kvm/Y%2ffkTs5ajFy0hP1U@google.com/ Signed-off-by: Thomas Huth <thuth(a)redhat.com&gt; --- docs/about/deprecated.rst | 13 +++++++++++++ 1 file changed, 13 insertions(+) diff --git a/docs/about/deprecated.rst b/docs/about/deprecated.rst index 15084f7bea..98517f5187 100644 --- a/docs/about/deprecated.rst +++ b/docs/about/deprecated.rst @@ -196,6 +196,19 @@ CI coverage support may bitrot away before the deprecation process completes.
