I've lost track of the conversation, are we currently proposing
the accelerator default to be "kvm" (as per the original patch
you quote here) or "kvm:tcg" ?

I'm not entirely sure which I prefer from an ARM perspective
For some time to come and for a lot of targets (ie any target
CPU except A15), having a default of "kvm" is going to cause
existing working commandlines to stop working. [I expect that
ARM-host qemu binaries will be built with CONFIG_KVM once ARM
KVM support lands, but the same binary will be run on hosts
without virtualization extensions.] On the other hand, perhaps
there just aren't really very many people who run QEMU on
ARM hosts, and so we can ignore them :-)
