With 1.5G RAM I usually get a desktop but then if anything crashes, and it seems like PackageKit is crashing often when under memory pressure (?), it kicks off systemd-coredump which makes the memory problem worse, and a bunch of oom killers start killing off various processes. In any case, I cannot successfully run the installer or Firefox by themselves.
Comparing Fedora 27 ISO to Fedora-Workstation-Live-x86_64-28-20180320.n.0.iso, the biggest difference is Fedora 28 packagekitd is soaking the CPU nearly 100% upon initial login and uses upwards of 20% of the available memory before settling down to 10%.. This is without launching anything. Whereas on Fedora 27, the memory footprint for packagekitd is 0.2%.
Fedora 27 ISO I can launch and use Firefox with a VM of 1.5G. I can't with Fedora 28, and the VM reports dozens of: Mar 22 00:47:49 localhost-live org.gnome.Shell.desktop[1707]: Window manager warning: HW cursor for format 875713089 not supported
And then just becomes unresponsive.
Anyway, tentatively it looks like 1G was a bogus minimum for Fedora 27, where 1.5G would have worked. And for Fedora 28 it needs to be 2G.
