Works, because the opt_name in accel_list[] are distinct, as you
explained in your commit message.
Apropos commit message. You first explain what you do, and only then
state the problem you're trying to solve. That's backwards. Start with
the problem. Only then explain your solution, if it needs explaining.
This one, I think, doesn't.
Suggested commit message:
vl: Report accelerator not supported for target more nicely
When you ask for an accelerator not supported for your target, you
get a bogus "accelerator does not exist" message:
$ qemu-system-arm -machine none,accel=kvm
KVM not supported for this target
"kvm" accelerator does not exist.
No accelerator found!
Suppress it.
