Hi All,

I am new to QEMU/libvirt

I was starting to learn the libvirt code,I was browsing the code how the guest network bandwidth to be set like we mention <inbound> <outbound> tags in the xml,but where in code exactly these values set to the guest interface.

I browsed the code a lot could not find it.Please help to understand how this works.

The bandwidth is set in virNetDevBandwidthSet() function: http://libvirt.org/git/?p=libvirt.git;a=blob;f=src/util/virnetdevbandwidth.c... 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). Michal
