Re: [kvm-unit-tests PATCH 1/4] scripts/arch-run: function to search qemu binary

[Balamuruhan S <bala24@linux.vnet.ibm.com>]

I have added the function in scripts/arch-run as per your suggestion.

I have tested the patches in x86 and PowerPC but for arm I don't have
the system to test. 

Thanks,
Bala
