[PATCH] arm/run: don't enable KVM if system can't do it

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



As ARM (and no doubt other systems) can also run tests in pure TCG mode
we might as well not bother enabling accel=kvm if we aren't on a real
ARM based system. This prevents us seeing ugly warning messages when
testing TCG.
