Do migration loop on both
libvirt-0.10.2-18.el6_4.5.x86_64
libvirt-0.10.2-18.el6_4.6.x86_64

Can not reproduce the problem on both version, so I check the source code of libvirt-0.10.2-18.el6_4.6.x86_64, find the patch already in
src/rpc/virnetsocket.c

int virNetSocketDupFD(virNetSocketPtr sock, bool cloexec)
{
    int fd;

    if (cloexec)
        fd = fcntl(sock->fd, F_DUPFD_CLOEXEC, 0);
    else
        fd = dup(sock->fd);
    if (fd < 0) {
...

So verify pass.
