Ok, looks like the version of kvm_stat in RHEL just doesn't have ppc support. Michael Ellerman posted a bunch of extensions to fix that which are merged upstream. I'll backport. These patches are also already included in the qemu-2.2 based branch. Miya et al, have you moved onto testing that yet? Verified the bug on following sw versions: Host kernel: 3.10.0-282.el7.ppc64le Qemu-kvm-rhev: qemu-kvm-rhev-2.3.0-5.el7.ppc64le Now the command output is as follows: [root@ibm-p8-kvm-02-qe cfg]# kvm_stat kvm statistics Event Total Current kvm_userspace_exit 10046876 7563 kvm_ppc_instr 10894 5 kvm_ack_irq 1218 0 kvm_userspace_exit(PAPR_HCALL) 61 0 (In reply to Gu Nini from comment #6) Deeper verify the bug on both ppc64be and ppc64le host with following sw versions: PPC64BE HOST: host kernel: 3.10.0-300.el7.ppc64 Qemu-kvm-rhev: qemu-kvm-rhev-2.3.0-13.el7.ppc64 PPC64LE HOST: host kernel: 3.10.0-300.el7.ppc64le Qemu-kvm-rhev: qemu-kvm-rhev-2.3.0-13.el7.ppc64le Now the cmd 'kvm_stat' could be executed without any problem.
