As it supposed to happen described on this doc:

What am I doing wrong?
I’m trying to install SLES 15 SP1 from SLE-15-SP1-Installer-DVD-x86_64-QU3-Media1.iso
and SLE-15-SP1-Packages-x86_64-GM-DVD1.iso on a VMWare Machine with both ISOs mounted as DVDs.
Thanks already for your time on reading this.
Hi and welcome to the Forum 
Did you check the iso image file size and checksums? It should be the SLE-15-SP1-Packages-x86_64-QU3-Media1.iso that is used with the QU3 installer?
Thank you @malcolmlewis ! I checked checksums and sizes. Only installation DVD was OK. Then I tried for several days to download second one. Everytime I got size correct but not checksum. Looks like they limit bandwidth somehow, which makes it a pain to way 4-6 hours for a 8Gb download only to get wrong checksum.
Finally I gave up and asked my infrastructure guys to bypass proxy and did the Extensions and Modules installation via Internet. There is some room for improvement here.
@FabioArmando I wonder if there are issues related to infrastructure changes in progress with the split from MicroFocus. Let me ask my SUSE Contacts to see if there are any issues…
