I’m planning to have this function in src/conf/netdev_bandwidth_conf.*,
however, an initial compilation yields following undefined reference from
qemu_process.c:
----
Making all in tests
make[2]: Entering directory `/home/ubuntu/libvirt-ups/tests'
  CCLD     domaincapstest
../src/.libs/libvirt_driver_qemu_impl.a(libvirt_driver_qemu_impl_la-qemu_pr
ocess.o): In function `qemuProcessStop':
/home/ubuntu/libvirt-ups/src/qemu/qemu_process.c:4847: undefined reference
to `virDomainClearNetBandwidth'
collect2: error: ld returned 1 exit status
----

What am I missing here? All I did was to add virDomainClearNetBandwidth()
to netdev_bandwidth_conf.c (and to .h for function prototype). I have
tried moving this function to domain_conf.c as well, however, didn’t see
any difference in behavior. All other functions from
netdev_bandwidth_conf.c/domain_conf.c are perfectly visible during
compilation.
I have attached the full patch.

Thanks,
Anirban
