It was simply turning the machine off using the power switch, then power it
on.

Well, I couldn't log in in any way (via console or sshd), so I had no other
choice. In your case you may have other options since you seem to be able to
somehow log in.
At any rate, if the system just sits there doing nothing, you'll have to
interrupt it one way or the other...

It's the kernel.sysrq setting as seen in /etc/sysctl.conf, which might work
to send some last-resort command to not-so-uglily shutdown a machine even
when Ctrl-Alt-Suppr doesn't work. I'm not sure that applies to your setup, I
never used nor really learnt about UM Linux (User Mode Linux I guess).

I just got error messages scrolling over all virtual consoles, without
typing anything. Again, I don't know if something special should/could be
done given your setup.
If console shows nothing special, I'd say
check /var/log/yum.log, /var/log/messages and "dmesg" command output.
