With F32 and previous versions I've been able to install Workstation and other spins

phase.
Is this expected?
FWIW, the "Everything-netinst" install of a KDE system did install just fine
with 1248MB assigned.
Currently using...
Fedora-Everything-netinst-x86_64-33-20200824.n.0.iso
Fedora-Workstation-Live-x86_64-33-20200824.n.0.iso
Fedora-KDE-Live-x86_64-33-20200824.n.0.iso
Are there any hints why it crashed in the journal? That is pretty
tight memory wise. Minimum RAM 2G is what's listed on
getfedora.org,
and 4G i s recommended. The biggest difference memory wise I can think
of between F32 and F33 is no disk based swap by default. It uses zram
based swap. And in such a tight case, only 50% may not be enough.
Even before the zram change though, I'd see ~250M of swap used with a
2G VM. So that means it's already under provisioned, and walking on
thin ice.
But we should make sure we have a complete explanation before making
adjustments. You could see if zram set to 75% and 100% help, just as
an extra data point. Create /etc/systemd/zram-generator.conf and edit
to include
[zram0]
zram-fraction=0.75
and then 'systemctl restart swap-create@zram0'
confirm with swapon and/or zramctl that its size is 75% that of totalmemory
You can do this prior to beginning the installation.
