Comment # 54 on bug 1193889 from Mark Post

I think I've figured out what the problem is, although not its cause. It
appears that the guest is not bringing up the enc800 interface. It seems that
NetworkManager is having issues.

This may because NetworkManager is trying to use dhclient to get an IP address
for the interface, instead of setting a static IP and route. I have no idea why
this might be happening, but perhaps someone else will.

So, over to the NetworkManager people to figure this out.

In the meantime, the problem with read_values is puzzling, but not contributing
to this problem. I will keep looking at it, however, since rebuilding it from
source on the system under test results in a working binary.
