[Libvirt-cim] [PATCH V2 3/3] cimtest: Add default network existence check to 06_parent_net_pool.py

[Xu Wang]

The default network card name is 'eth0' or 'em1'. But if the network
card name doesn't contain those values, error would occur. So this patch
will check if the default network card name exists in the network
card name list. If not, the network card name would changed into
the first one in the network card name list.
