[Rafael Folco]

Public bug reported:

1) Ubuntu Release
Description:	Ubuntu 14.04.2 LTS
Release:	14.04

uname -m
ppc64le

2) Version (i386)
qemu-kvm:
  Installed: 2.1+dfsg-4ubuntu6
  Candidate: 2.1+dfsg-4ubuntu6
  Version table:
 *** 2.1+dfsg-4ubuntu6 0

3) Missing qemu-kvm wrapper package is a dependency to devstack

>From a x86_64 ubuntu machine:
ubuntu at rfolco-ubuntu:~$ sudo dpkg -L qemu-kvm
/.
/usr
/usr/bin
/usr/bin/kvm
/usr/share
/usr/share/doc
/usr/share/doc/qemu-kvm
/usr/share/doc/qemu-kvm/copyright
/usr/share/doc/qemu-kvm/NEWS.Debian.gz
/usr/share/man
/usr/share/man/man1
/usr/share/man/man1/kvm.1.gz
/usr/bin/qemu-system-x86_64-spice
/usr/bin/kvm-spice
/usr/share/doc/qemu-kvm/changelog.Debian.gz
ubuntu at rfolco-ubuntu:~$ file /usr/bin/kvm-spice
/usr/bin/kvm-spice: symbolic link to `kvm'
ubuntu at rfolco-ubuntu:~$ file /usr/bin/kvm
/usr/bin/kvm: POSIX shell script, ASCII text executable
ubuntu at rfolco-ubuntu:~$ cat /usr/bin/kvm
#! /bin/sh
exec qemu-system-x86_64 -enable-kvm "$@"

On ppc64le, /usr/bin/kvm script (packaged in qemu-kvm) should be a wrapper to qemu-system-ppc:
#! /bin/sh
exec qemu-system-ppc -enable-kvm "$@"
