Folks,
I'm an OVirt newbie having troubles setting up my first Hosted Engine and am
stumbling. In this case I think it may be because of the following two set-up questions.
Enter the name which will be used to identify this host inside the Administrator
Portal [hosted_engine_1]:
Please provide the FQDN for the engine you would like to use.
This needs to match the FQDN that you will use for the engine installation
within the VM.
Note: This will be the FQDN of the VM you are now going to create,
it should not point to the base host or to any other existing machine.
Engine FQDN: []:
My read of this is that the first question is asking for the name of the host, while the
second question is asking for the name (FQDN) of the guest vm which will be the
hosted-engine. Is this correct?
I'm also presuming that a) the first question should be the hostname of the host, and
b) that both the host and guest hostnames should resolve to IP addresses.
Thanks
Mark

Mark,
Enter the name which will be used to identify this host
inside the
Administrator Portal [hosted_engine_1]:
This is the name used for the host inside the Administrator Portal, so basically
the name of the VM inside the system.
This does not have to be the hostname, but there are also no objection for it.
Engine FQDN: []:
Yes, you are correct. This must be
the FQDN of the host, resolvable to IP.
This fqdn will be used to access the administration portal.

If I understand you correctly, both questions apply to the hosted engine vm. Correct?
(If so, I'm glad I asked, because I initially and incorrectly thought that the first
question referred to the bare metal machine that hosts the hosted engine vm.)
Thanks

If I understand you correctly, both questions apply to the hosted engine vm. Correct?
No.
The first question is about the host, but not about its address or dns name.
It's about the name it will have in the engine, the one you see in the admin ui,
in "Hosts", as "Name". After too many questions about this question,
we decided
to remove it, and in 4.1 it will simply default to the hostname. You'll still be
able to set it by manually editing the answer file or passing otopi
env, but will
not be prompted for it.
The second question is indeed about the name that will be used to access
the engine vm.
Then there is a third item, which we do not ask about: The name that the
engine should use to access the host. This is what you see in the admin ui,
in "Hostname/IP". This item is determined the following way, for the first
host: You are prompted for a NIC to use for the management bridge, we check
the IP address of this NIC, then do a reverse-lookup (gethostbyaddr) on this
address, and use the result. So you should make sure that this nic has an
IP address, that this address has a name (in /etc/hosts or dns), and that
this name will also be resolvable and point to the host, when used inside
the engine vm (again, by either using dns or manually setting it in
/etc/hosts there).
(If so, I'm glad I asked, because I initially and incorrectly thought that the first
question referred to the bare metal machine that hosts the hosted engine vm.)
Hopefully the above clarifies this. Please do not hesitate to ask if
there are still questions. Also, suggestions for better texts, to make
this simpler for the admin, are more than welcome! :-)
Best,
Thanks

Yedidyah - very helpful! Thanks.
A follow-up question re the FQDN for the hosted engine: My understanding is that the FQDN
must be resolvable when "hosted-engine --deploy" is executed. However, should
the IP that the FQDN resolves to also be assigned/up when "hosted-engine
--deploy" is executed?

When deploying the first host, this IP can't be up, as the engine vm
does not exist yet.
And, BTW, it indeed needs to be resolvable, but you can change the address
between this prompt and the actual point where we try to connect to it. So
if you can't control the address (say, you use dhcp, and either do not
control it or do not want to use static reservations), you can do something
like this:
1. Choose a fqdn for the engine, add it to /etc/hosts with a fake address
2. Start deploy
3. When the engine vm is up, and got an IP address, edit /etc/hosts on
the host to point to this address
4. Continue as usual.
No need for this if you do control dhcp - you can choose a MAC address,
add a static reservation for it, and supply it when prompted.

Mark,
hosted_engine_1 is of course the name of the host in the system.
Sorry for the confusion.

Correct?
(If so, I'm glad I asked, because I initially and incorrectly thought that
