[ovirt-users] Single server hosted engine... almost there

[Derek Atkins]

Hi,

You need to make sure resolv.conf is correct (both on the host AND on the
engine vm).

So:   dig hostname
(without the @local-ip)

As for the VM not coming up...  I'm not sure how to delay "engine-setup"
run.  I presume you're running an engine appliance -- I ran my own CentOS
install on the engine.  The logs imply it's suggesting you can access the
engine VM console, but maybe it's exiting quickly?
