So far I have just tested this on one computer with the XFCE and Games i686 spins. But that computer has normally rebooted from Live Iamges in the past. I tried both the logout / restart option from the XFCE desktop and reboot from a root command line. In all cases things went to mirroed screens with a fedora logo on a blue background. At that point control alt delete, escaope and delete didn't appear to have any effect. I one case I waited about 10-15 minutes to see if there was a short systemd hang. I eventually ended up powering the system off to reset things.
try booting without rhgb quiet so you can see the shutdown messages.
This is machine specific. I tried this on two laptops at home and they rebooted normally. I'll see if I can get more info on my work machine tomorrow.
This isn't a livecd-tools issue, I would guess it is systemd since shutdown and reboot are now owned by it.
It'll be hard to fix without further debug information... Can the spin iso that hangs be downloaded from somewhere?
http://download.fedoraproject.org/pub/fedora/linux/releases/test/21-Alpha/Live/i386/Fedora-Live-Xfce-i686-21_Alpha-1.iso reboots just fine for me (under kvm). To debug this it, please try appending " systemd.debug-shell" at the boot prompt. This opens a root shell on tty9. When the boot hangs, you should be able to use ctrl-alt-f9 to switch to it. If you are not able to switch, this is most likely a hardware/kernel/driver issue. If you are able to switch, look at the 'systemctl list-jobs', 'journalctl -e', etc. This should show what the problem is.
I did a reboot without rhgb or quiet and the last entry was: reboot machine restart The other thing I saw today was a hang with a non-live reboot on the same machine. This was also F21, but with a 3.17 kernel.There was not a systemd update betwwen the boot and reboot. (Systemd updates often cause reboot hangs.) There wasn't any log of the shutdown. The mouse pointer froze imediately and I had to power off before I could reboot. That is different than what I was seeing with the live image reboot hangs. So this might be something separate.
I should be able to try out the debug shell this afternoon.
I tried out systemd.debug-shell and I wasn't able to get into the debug shell after triggering a reboot. So this doesn't seem to be systemd's problem.

I did have the same problem with the following iso's fedora-live-xfce-i686-21.5 xubuntu 14.10-desktop-i386.iso but sucseeded with the following : linux Mint rebecca 17.1 xfce R.C. version. linux Mint rebecca 17.1 Mate Since my computer is old one Dell demention4500 (10 years old); I have to go back to : Fedora-live-XFCE-i686-20-1-iso for a new installation. after loading and updating I can'nt load at the boot time the latest kernel which is 3.17.200; I have to select and load the original 3.11.10-301. apperently boot proccess does not like the latest kernel or the placement of files or modules is out order somehow. uname -a Linux localhost.localdomain 3.11.10-301.fc20.i686 #1 SMP Thu Dec 5 14:21:31 UTC 2013 i686 i686 i386 GNU/Linux Befor the use of fedup or Fedora-upgrade which messed up my installation the system was running the latest kernel and I had plenty of power. Is XFCE is out of favor!? It keeps a lot of old computers acting like new. Thanks.
This message is a reminder that Fedora 21 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 21. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '21'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version.

Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
