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: https://lore.kernel.org/kvm/Y%2ffkTs5ajFy0hP1U@google.com/ Reviewed-by: Daniel P.
