I might have missed that; I don't recall for certain as there is a lot
of logging going on in various places, it's hard to know where to look
sometimes. Then there's all the errors that seem to happen that aren't
really problems AFAICT.
Anyway, I just ran through an attempted deploy again and I don't see
ovirtmgmt mentioned anywhere in /var/log/vdsm/vdsm.log, nor anything
else in that file looking majorly bad WRT networking. I do see a bunch
of errors related to storage though. Any hints what I should be search
for? Would it be best just to post the file somewhere -- it's a rather
portly 12MB ATM.
And just because I'm feeling stupid right now.... I don't need to do
anything special WRT configuring networking prior to running
hosted-engine --deploy do I? I mean its got working IP, DNS, etc. but
IIRC, the installation handles all the setup of ovirtmgmt, right?
