A quick search of ‘rtnl_tc_get_ops’ on the Google machine revealed that it’s part of libnl (netlink protocol ibrary suite).  Please check and ensure that you have libnl devel package installed on your system.

I am new to QEMU and want to use its fault tolerance feature by "Michael Hines" described in this page

I followed these steps 
$ git checkout 'mc'
$ ./configure --enable-mc

and installed the required libraries, but when I run the 'make' command I get the following error:

  CC    migration-checkpoint.o
migration-checkpoint.c: In function ‘mc_enable_buffering’:

     if (!(ops = rtnl_tc_get_ops(tc))) {
cc1: all warnings being treated as errors
make: *** [migration-checkpoint.o] Error 1

Is this due to compiler version? Please advise.
