[libvirt-users] libvirt: error : internal error: cannot apply process capabilities -1

Hi All, I am running libvirt-1.1.2 on Scientific Linux release 6.1 (Carbon). I compiled the libvirtd rpms and installed them on to my system. I see this error 2014-04-11 05:37:42.351+0000: 12378: error : virCommandWait:2348 : internal error: Child process (LC_ALL=C PATH=/sbin:/usr/sbin:/bin:/usr/bin /usr/libexec/qemu-kvm -help) unexpected exit status 1: libvirt: error : internal error: cannot apply process capabilities -1 Whenever libvirtd restarts. Because of this error I also cannot create a domain with os_type set to "hvm". Virsh capabilities also does not list this os_type. Can someone let me if I am missing something obvious? Santhosh
