Newbie Questions
Hello,
I'm just getting started with VCL and I have some questions. First, Does
the management node have to have DHCP running? I'm assuming this is used to
give IP's to compute nodes(machines handed out to users?) what happens if a
DHCP server is already in place but not part of vcl? Sorry if I seem
confused , as I mentioned I just started looking at this. I'm just trying
to set up a proof of concept. Currently we have a vmware environment which
I was thinking of using as the web server and management node and the other
3 physical machines as test boxes that will be handed out to users and
perhaps one virtual machine so I can have a mixed environment with one
virtual node and 3 physical nodes. Can someone help me get started. If my
vmware webserver and management node has a 10.10.11.X address which I plan
on using for public access to make reservations then my private address
will need DHCP?

John,
I said user reachable addresses rather than public addresses because you could
set up VCL to only be used internally, or you could require a VPN to access
VCL, allowing internal addresses to be used on the VCL "public" network. For
clarity, I'll just start using "public".
The requirement that each node have a public address is something leftover
from the initial creation of VCL at NCSU where we have quite a number of
public addresses. We are aware that many people in the community would like
to use NAT to reach the provisioned nodes, and we plan to have the NAT support
contributed by a community member included in the next release of VCL
(hopefully released somewhere around Feb. 2014).
When someone makes a reservation in VCL, VCL provisions the node and then
displays information to the user on how to connect to the node. So, for NAT
to work, the code has to be modified to be aware of the NAT being done so that
it can give the user the correct information about how to connect to the node.
Connection is typically done using RDP for Windows reservations and either
xRDP or ssh for Linux reservations.
It is definitely fine to run the web frontend and the vcld backend code on the
same VM. Many people are doing this. You can also have that same VM
provision both bare metal nodes and VMs.

Thanks Josh.
I guess part of it is my lack of strong networking skills or I'm over
thinking this. Usually companies only have one public or perhaps several
address that they purchase and they then use switches to NAT certain ports
like port 80 to an internal RFC1918 addresses. This is where I'm getting
confused because the VCL front end will have a DNS entry that will route
users to the VCL web front end when they go to myvcl.whatever.com. Can you
clarify on what you mean by user reachable addresses? Won't the switch be
doing the NAT? I also plan on using the web frontend and management node on
same server. The web front end will be a virtual machine running on
vmware5.X. Is it possible for one management node to provision both
baremetal machines and vm machines?

John,
Welcome to the VCL community! Our apologies that the documentation is
somewhat lacking.
VCL does not do NAT out of the box. There is a JIRA (our bug/feature tracking
system) issue with code attached to add NAT. Out of the box, you'll need to
have user reachable addresses available for each node.
VCL uses two separate networks typically referred to as private and public.
The private network is used by the management node to provision and control
the available nodes. The public network is used so that end users can connect
to a reserved node. You can use RFC1918 addresses on both the private and
public networks. However, if you do, you'll need some sort of NAT available
for your users to connect to the reserved nodes (unless you are doing all of
this in a private lab where you can still connect to the reserved nodes even
though they aren't technically on a public network).
Back to the DHCP question - if you are planning on doing bare metal
provisioning, you'll need to set up xCAT for this, which includes setting up
DHCP for the private network. You must have your own DHCP server on the
management node for the private network so that xCAT can update it to give the
nodes information on how they are to boot.
Let me know if you need any of that clarified.

I might have worded it wrong. my vcl frontend will have two nic cards
..what are acceptable addresses for those Nics for private and public. I'm
under the impression that one nic will have like a 192.168.X.X but will be
connected to public network or users from the outside will go to
www.myvlc.whatever
and it will be natted to the 192.168.X.X nic of the front end. Am I getting
this right?

Thanks for the Reply,
Currently, our DHCP server is windows bases, will importing dhcp.conf work?
also, I'm doing this for internal proof of concept so if I can't use
RFC1918 for public how would I test this internally. Sorry, I'm not much of
networking guy, I can run this by the network admin but I'm just trying to
understand how this will work. So each node will need to be exposed to
outside world? I'm not to clear on this..Thank You

Hi John
You can use existing DHCPd server. Once you add VCL computers (type: virtualmachine) you should get a dhcpd.conf file (for private addresses), which you need to import into your existing DHCPd server. This will allow your VCL VMs to get the right IP address.
For public you don't need static DHCP, VCL will connect to a VM and pull public address during reservation.
(I'm not sure you can use 10.10.11 as public, there was something in the code excluding RFC1918 addresses...)

Hello,
I'm just getting started with VCL and I have some questions. First, Does the management node have to have DHCP running? I'm assuming this is used to give IP's to compute nodes(machines handed out to users?) what happens if a DHCP server is already in place but not part of vcl? Sorry if I seem confused , as I mentioned I just started looking at this. I'm just trying to set up a proof of concept. Currently we have a vmware environment which I was thinking of using as the web server and management node and the other 3 physical machines as test boxes that will be handed out to users and perhaps one virtual machine so I can have a mixed environment with one virtual node and 3 physical nodes. Can someone help me get started. If my vmwarewebserver and management node has a 10.10.11.X address which I plan on using for public access to make reservations then my private address will need DHCP?
