[libvirt] [tck PATCH] network tests: change network address to avoid commonly-used subnet
by Laine Stump 08 Jun '18

08 Jun '18

My own machine has a virtual network on 192.168.123.0/24, and I've been told that it's a common selection for people who create a second network after libvirt's default (and in the past was used as a manual alternative for the default network itself when 192.168.122.0/24 casued a conflict). Changing to 192.168.97.0/24 also isn't foolproof, but it's much less likely to encounter a conflict leading to a failed test.

[libvirt] [tck PATCH] scripts: shorten netdev/domain name to prevent overflow
by Laine Stump 08 Jun '18

08 Jun '18

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.
