Hi All, This patch series support enabling HV and PR KVM together in the same kernel. We extend machine property with new property "kvm_type". A value of 1 will force HV KVM and 2 PR KVM. The default value is 0 which will select the fastest KVM mode. ie, HV if that is supported otherwise PR. With Qemu command line having -machine pseries,accel=kvm,kvm_type=1 [root@llmp24l02 qemu]# bash ../qemu failed to initialize KVM: Invalid argument [root@llmp24l02 qemu]# modprobe kvm-pr [root@llmp24l02 qemu]# bash ../qemu failed to initialize KVM: Invalid argument [root@llmp24l02 qemu]# modprobe kvm-hv [root@llmp24l02 qemu]# bash ../qemu now with -machine pseries,accel=kvm,kvm_type=2 [root@llmp24l02 qemu]# rmmod kvm-pr [root@llmp24l02 qemu]# bash ../qemu failed to initialize KVM: Invalid argument [root@llmp24l02 qemu]# [root@llmp24l02 qemu]# modprobe kvm-pr [root@llmp24l02 qemu]# bash ../qemu if don't specify kvm_type machine property, it will take a default value 0, which means fastest supported. -aneesh -- To unsubscribe from this list: send the line "unsubscribe kvm-ppc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
