Shawn,
Just to be sure, are you running "ps aux" as root? Because if you are
"shawn" when you run it, then depending on which groups "shawn" is in,
it
may not divulge root's processes.
You might also try "libvirtd -v" - which will start it in the foreground
rather than as a daemon, and be more verbose about what it's doing. So if
it's failing to run for root, that might tell you why.

Will,
I have been running the libvirt daemon as "shawn" because when running as
"root", "ps aux | grep libvirtd" does not show that the daemon is
running. So I
uninstalled and re-installed libvirt as "root" but to no avail. For some
reason
I cannot start the daemon as root. I don't get any errors when doing this, it
just doesn't run.

Shawn,
Are you starting libvirtd as root, from a # prompt rather than as shawn,
from
a $ prompt? If not, try "sudo -i" to get to a root prompt and start it
from
there. If it still puts libvirt-sock in the wrong place, did you compile
this as root? Perhaps it sets up to default to a user's home if that user
compiles it. No idea.
Also, just to be lazy, you can get away without the "-c qemu:///system"
part
- virsh defaults to that.
