When new pids are more than 9 digits long The nwfilter tests use tck-test${pid} as the auto-generated name for their test domains (and therefore the tap devices created for those test domains). When the pid is > 9 digits long, the total length of the name is > 16, which is the maximum length for any network device name (IFNAMSIZ), and this causes failure to create the tap device, thus failure of the test: /home/laine/devel/libvirt-tck/scripts/nwfilter/050-apply-verify-host.t .. error: Failed to start domain tck-test10513851 error: Network interface name 'tck-test10513851' is too long: Numerical result out of range The solution is to just remove "test" from the name template, so pid can be up to 12 digits long before the test fails.
