I haven't used CentOS as a KVM host yet, only Fedora, but your setup
still puzzles me...why do you have a brand new qemu-package (as in
"not from the CentOS/RHEL repositories") installed? I would guess that
this package would conflict with the kvm package and mess things up.

Your error message mentions /usr/bin/qemu-system-x86_64 as the
executable. If you run
rpm -qf /usr/bin/qemu-system-x86_64
does it then tell you that this file belong to the qemu package? If
so, I believe this is your problem...you try to use qemu, which has
partial KVM support, instead of using qemu-kvm (which is the "real"
KVM userspace executable that originates from the kvm package). I
don't think the arguments supported by qemu-system-x86_64 and qemu-kvm
are the same, which probably could be the cause of the client not
booting and libvirt/virt-manager failing.

Best Regards
