KVM unsupported a 64-bit guest on a 32-bit host

KVM unsupported a 64-bit guest on a 32-bit host

HOST i686 and qemu-x86_64 with enable-kvm : detectes an i686 CPU.

Can KVM run a 32-bit guest on a 64-bit host? What about PAE?
http://www.linux-kvm.org/page/FAQ#Can_KVM_run_a_32-bit_guest_on_a_64-bit_host.3F_What_about_PAE.3F

KVM supports 32-bit guests on 64-bit hosts, and any combination of PAE and non-PAE guests and hosts. The only unsupported combination is a 64-bit guest on a 32-bit host.

If you are running a Windows Virtual Machine and have problems enabling PAE in your guest see the Windows PAE Workaround page.

2. enable-kvm and modify command line

from /boot/bzImage change to  /boot/bzImage64

Loading /boot/bzImage64… ok

Loading /boot/rootfs.gz… ok

This kernel requires an x86-64 CPU, but only detectes an i686 CPU.

Unable to boot - please use a kernel appropriate for your CPU.

IMHO:

HOST i686 and qemu-x86_64 with enable-kvm : detectes an i686 CPU.

should be use i686 kernel ( bzImage ),

but the slitaz-rolling-core64.iso only has bzImage64, no bzImage.

Kernel Support for miscellaneous (your favourite) Binary Formats v1.1
==============================================================
https://www.kernel.org/doc/Documentation/binfmt_misc.txt

This Kernel feature allows you to invoke almost (for restrictions see below)
every program by simply typing its name in the shell.
This includes for example compiled Java(TM), Python or Emacs programs.
To achieve this you must tell binfmt_misc which interpreter has to be invoked
with which binary. Binfmt_misc recognises the binary-type by matching some bytes
at the beginning of the file with a magic byte sequence (masking out specified
bits) you have supplied. Binfmt_misc can also recognise a filename extension
aka '.com' or '.exe'.

First you must mount binfmt_misc:
mount binfmt_misc -t binfmt_misc /proc/sys/fs/binfmt_misc

Chrooting to: /opt/rootfs-armhf/
http://alanyih.blogspot.tw/2013/06/slitaz-setup-rootfs-armhf.html

3. Mount the binfmt_misc handler
# modprobe binfmt_misc
# mount -t binfmt_misc binfmt_misc /proc/sys/fs/binfmt_misc 

4. register our format with the kernel via the procfs
root@slitaz:~# echo ':arm:M::\x7fELF\x01\x01\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00\x28\x00:\xff\xff\xff\xff\xff\xff\xff\x00\xff\xff\xff\xff\xff\xff\x00\xff\xfe\xff\xff\xff:/usr/bin/qemu-arm-static:' > /proc/sys/fs/binfmt_misc/register

libhoudini: What It Means for Developers

libhoudini is a proprietary ARM translation layer for x86-powered Android devices. It allows an app that has NDK binaries for ARM, but not x86, to still run on x86 hardware, albeit not as quickly as it would with native x86 binaries.

Given ARM’s near-stranglehold on the Android ecosystem, libhoudini is hugely useful for Intel and hardware vendors interested in using Intel’s mobile CPUs. Without it, only apps that ship x86 NDK binaries would be compatible with x86-powered devices like the Samsung Galaxy Tab 3 10.1” tablet. Some developers probably skip x86 NDK binaries, because they are not aware of popular x86-powered devices, or lack one for testing, or are concerned over APK size. The Play Store for x86 would shrink substantially from the million-plus apps available to ARM devices, to those that do not use the NDK or happen to ship x86 binaries. libhoudini makes ARM-only NDK binaries usable on x86, giving x86-powered Android devices access to more of the Play Store catalog.
