I think there would be interest. I for one would be very happy to hear about
it

This is definitely not a simple talk. I think there is no way you can
present it in details all across, especially as it involve lots of
technologies.
I mean, it involve virtualization, networking (VRRP), LVM or cluster file
system, DBRD or SAN storage just to name a few. The only way you can deliver
it in time is to generalize some of the content.

If I was in your shoe, I would skim over simple stuff, things that tend to
work easily and spend most of the time were really hard to get going. When I
mean skim, I mean mention it just enough that one can tell how its related
to the main talk, alternatives and their advantages/disadvantages etc.

The meat of the talk I assume would be DBRD and HA. For these two services,
you can go deep as explaining every section of the configuration file, so
the lion share of time should go toward these two in my humble opinion And
to be frank, they also tend to be the hardest to get going, all the more
justifying the extra effort needed there. Ok, I admit cluster file system is
also a pain, but one has to make a choice.

You can also consider sending out the presentation before the talk - people
can look at it and be up to speed when you are presenting. Or else share
your notes on the project at the end of presentation and everyone can look
at the detailed stuff  later and fill up the gaps. In short, the listerners
also have to do a bit of homework as the time will not be enough for very
detailed talk.

Anyway, thats just my 2 cents
