It reported in my bash shell session, that was supplied by RHEL 7.1.

I get codes from 
'https://www.kernel.org/pub/scm/virt/kvm/kvm-unit-tests.git/', build in 
my kvm env.
OS info: RHEL 7.1
Linux version: 3.10.0
Qemu version: 2.3.0
CPU of machine: Intel(R) Xeon(R) CPU           X5670  @ 2.93GHz

Are these infomation adequate?

I will use your configurations to run kvm-unit-tests too.
