Migration from 12.5 to 15.1 (default) fails (again?, cf. BZ1182234) due to DNS
issue. Please note that networking is default one - ie. DHCP, no changes.
The issue seems to be that on DMS live env resolv.conf is empty.
Steps to reproduce
==================
1. SLES 12.5 with DHCP networking, see below settings
2. install LES15-Migration-2.0.34-6.x86_64
suse-migration-sle15-activation-2.0.33-6.30.4.noarch
3. reboot
(Tested on libvirt)
Info from 12.5
