The bandwidth is set in virNetDevBandwidthSet() function:
http://libvirt.org/git/?p=libvirt.git;a=blob;f=src/util/virnetdevbandwidth.c;h=b06ed4c63c1e64736718b880b1821d745d7f31c2;hb=HEAD#l60
The basic idea is to call /sbin/tc a few times with the correct
arguments (the path to the binary may change through different systems).
