Add the keyworrds "Regression" ,because rhel7.0GA not have the problem. Bug reproduced. Fix submitted upstream. Fix included in qemu-kvm-rhev-2.1.2-7.el7 Test this bug on latest version,not hit the problem any more Version: Host: # uname -r 3.10.0-205.el7.x86_64 # rpm -q qemu-kvm-rhev qemu-kvm-rhev-2.1.2-8.el7.x86_64 Steps: 1.boot guest with "-smp 2,sockets=1,cores=4,threads=1 " Results:guest work well Addtional: test other paramerters ,work well According to above test ,this bug fixed.we can verify this bug.
