[Bug 1389897] Re: no way to install "enough qemu for kvm" in a cross platform way

[dann frazier]

** Description changed:

- There is currently no way to install just enough qemu to have kvm work.
- On x86 you can install qemu-kvm, but even on the other architectures
- where this is built (e.g. armhf) it depends on qemu-system-x86.  Or you
- can install qemu-system but that installs way more than you need.
+ [Impact]
+ There is currently no way to install just enough qemu to have kvm work.  On x86 you can install qemu-kvm, but even on the other architectures where this is built (e.g. armhf) it depends on qemu-system-x86.  Or you can install qemu-system but that installs way more than you need.
  
- Quick consensus seemed to be that qemu-kvm should depend on the
- appropriate qemu-system-$ARCH.
+ [Test Case]
+ $ apt-get install qemu-kvm
+ This should pull in the appropriate qemu packages to run KVM on the host.
+ 
+ [Regression Risk]
+ This is a new package for some archs (arm64/powerpc/ppc64el), so that minimizes the risk of regression there. The biggest risk I see is if someone on armhf was using 'apt-get install qemu-kvm' as a shorthand for installing qemu-system-x86. It seems unlikely (read: very slow) for someone to try to be running emulated x86 on armhf. That said, the upgrade to this won't force qemu-system-x86 off of their system - it would just be a behavior change for new installs.
