Let me take the opportunity to dissect some of this:

            236ms spice-vdagentd.service

I don't see why this is on by default. According to this bug report this
should have been pulled in on-demand only:

Adam is running a spice enabled vm, so it is getting started
because he has the required virtual hardware.



https://bugzilla.redhat.com/show_bug.cgi?id=876237

            233ms abrt-ccpp.service

https://bugzilla.redhat.com/show_bug.cgi?id=963184

            160ms fedora-loadmodules.service

Somebody should file bugs against all packages that still drop something
into /etc/sysconfig/modules/.

I see that kvm and bluez do this still. I filed these bugs now:

https://bugzilla.redhat.com/show_bug.cgi?id=963193
https://bugzilla.redhat.com/show_bug.cgi?id=963198

             79ms systemd-modules-load.service

Ah, cute, on my machine the only reason this is pulled in is
/etc/modules-load.d/spice-vdagentd.conf -- which also pulls in our old
friend uinput (see above).

https://bugzilla.redhat.com/show_bug.cgi?id=963201

I'm fine with dropping the config file from spice-vdagent as long as
something then creates the /dev/uinput device node, so that module
auto-load will actually work, without the device-node pre-existing
trying to use /dev/uinput will just cause a -ENOENT failure.

             54ms ksm.service

I thought the kernel would do this internally these days without
userspace interaction.

At a minimum we should consider not starting these *inside* vms

Hans
