I got the same configure output. > And I compiled and ran qemu, then I met the same issue as I describled before. Oh, adding '--enable-kvm' when running qemu will work. The following command line enables kvm when qemu starting. ./x86_64-softmmu/qemu-system-x86_64 -smp 2 -m 1024 -device pci-assign,host=0e:00.0 -hda /root/rhel6u1.img --enable-kvm But it didn't need to add '--enable-kvm' two weeks ago. Must we add this parameter from now on if we want to use kvm ? > > Check /dev/kvm permissions. > I have the permission for /dev/kvm.
