Issues with devstack on both Fedora 17 and 18

[Kyle Mestery (kmestery)]

Tried this on the openstack-dev list, but didn't hear anything, thought I'd try the Fedora Cloud mailing list since this is Fedora specific.

On both Fedora 17 and Fedora 18, when I use devstack, after a devstack run my D-Bus daemon has died such that systemctl no longer works. If I try to run systemctl, I see this:

[kmestery at fedora-mac devstack]$ systemctl 
Failed to get D-Bus connection: No connection to service manager.
[kmestery at fedora-mac devstack]$ 

I've googled around for this, but haven't seen anything concrete. Does anyone have any idea what might be happening, or where I could look to understand why this is happening? A reboot of the host fixes things, but another devstack run leaves the system in the same state.

Thanks!
