I get to the Installation Summary page, and Source Selection says "Source changed - please verify" Then "An unknown error has occurred" with a huge dump of info. In there, I see lots of ERRs about multipath (which I'm not using) and WARNINGs about systemd cannot add dependency for job.

I know that step one is to get to virtual consoles to look through log messages and stuff, but I have not been able to find a way to do that in the web console for vCenter Server. Googling suggested Ctrl-Alt-Space Fx, but that changes the console of my host.
