It looks like this script configures a bridge with yast.

> https://openqa.opensuse.org/tests/841756/modules/virt_install/steps/1/src).

And this script doesn't explicitly specify a '--network' option, which
according to the virt-install man page gives you:

"If this option is omitted a single NIC will be created in the guest. If there
is a bridge device in the host with a physical interface enslaved, that will be
used for connectivity. Failing that, the virtual network called "default" will
be used. This option can be specified multiple times to setup more than one
NIC."

So it seems virt-install should find the bridge created by yast and use it.
Apparently that is not the case since it instead uses the inactive default
network.
