Network Setup
All, From the documentation, VCL has to have two networks, Private and Public. My question is can they be setup within VMware where the public IP can routed through the eth0 and get a DHCP address and the private IP can be routed through a vSwitch? Do all of you have two vlans provided by a physical switch? Any info would be helpful.

Aaron,
You're not being a stick in the mud. I think it's great that you tested it
well enough to find a few things that need to be corrected - that's the whole
point of having a community vote to do a release. I definitely consider the
Shibboleth issue big enough to cut a new RC (even though that requires a new
vote).
All,
Aaron has some good points. I think we should fix the issues he mentioned and
cut RC2 for 2.3. This isn't an official vote process, but please share any
thoughts you have.

Sorry to a stick in the mud, guys, since I'd certainly like to see 2.3
released soon, but I encountered a few issues that I think should be
fixed before cutting the release.
I installed the release candidate using a fresh database, testing
against a vCenter provisioning engine and Shibboleth authentication. I
was using a 64-bit Windows 7 image.
The first issue I encountered was that each time the management node
calls 'get_file_contents', the contents of the target file are printed
to the log. This is generally not an issue, but when a slice of the
registry is retrieved, that amounted to ~30,000 lines in my logfile.
And that happens each time an image is reloaded. (Somehow I hadn't
noticed this with the code from about two weeks ago). I can certainly
see the usefulness of this during development, but I don't like the
fact that this is the default behavior for a release. For now, I would
suggest modifying line 1789 of
OS.pm:
-my ($exit_status, $output) = $self-execute($command);
+my ($exit_status, $output) = $self-execute($command, 0); # do
+ not
print the cmd output to the log
Later, it could be nice to make this somewhat more configurable.
Second, if the system is using Shibboleth it is not possible to handle
users who have not previously logged in (i.e. adding someone to a
group). There are two bugs preventing this from working properly.
First, if someone enables ALLOWADDSHIBUSERS in conf.php but doesn't
define a value in $addUserFuncArgs (I would anticipate this to be what
most people using Shib would do, since there is no documentation about
what that array is for), the initGlobals() function does not properly
populate the addUserFuncArgs array. This can be fixed by adding
$addUserFuncArgs to the list of 'global'
values on line 68 in utils.php -- the current code is just modifying a
local value, not the global one:
-global $affilValFunc, $addUserFunc, $updateUserFunc;
+global $affilValFunc, $addUserFunc, $updateUserFunc,
+ $addUserFuncArgs;
Once that change is made, though, there is also a SQL query expecting
a 'validated' field in the users table. This field, however, does not exist.
It is in neither update-vcl.sql nor in vcl.sql:
vcl.sql, line 1079:
+ `validated` tinyint(1) unsigned NOT NULL default '1',
and update-vcl.sql, lines 827-
+ --
+
+ --
+ -- Table structure for table `user`
+ --
+
+ CALL AddColumnIfNotExists('user', 'validated', tinyint(1) unsigned
+ NOT
NULL default '1'); +
Once these two changes are made, however, I am able to add shib users
exactly as the documentation suggests.
Otherwise, everything else looks good.

As a general guide, I have found the following to be reasonable. Other admins, please share your opinions. For a single VM host with 12 virtual CPU and 98 GB RAM, I typically allocate 25 Windows VM. When necessary, I have raised it to 32 Windows XP machines. For linux based images, I have used 50 VM without issues. Monitor the performance tab on your vSphere client to see if the host is over-worked. On Virtual Machines that require higher performance, I usually will not place them on a host with more than 10 working VM. But the most important thing is to watch the performance closely.

If the campus is closed for any reason [insert any disaster scenario here] and it is desired to continue teaching face to face courses (which are the majority of all of our courses) this can be done online. That is, this can be done online if we have a sufficient number of synchronous meeting servers available (we've been using Elluminate, but it could be any such software.) How many servers? Dozens, hundreds? It makes no financial sense to buy and install them and keep them there just in case. Here's where the VCL can take over and handle this - with one image of the server software in storage. When required, it can be loaded on any number of servers and the instructors and students can all be online from home and the courses continue. Of course, this use would displace some other uses - and that has to be arranged - but most of the student use for homework and projects is somewhat flexible - and likely can be displaced into the 10pm-10am lower use half of the day. The degree to which some uses are displaced to make place for others is a policy issue, and the VCL can be used for this. --henry On Wed, May 9, 2012 at 8:19 PM, Sanders, Arbin D asand...@nccu.edu wrote: All, ** ** I am apologize in advance for posting to both groups but I think each one has its own unique info and opinions.

Please review the following pages. http://incubator.apache.org/guides/graduation.html http://incubator.apache.org/incubation/Incubation_Policy.html#Graduating+from+the+Incubator There are many items described in the ASF graduation documentation which we have obviously satisfied (create a release, etc). The following are issues that I feel either need to be addressed, would be concerned about regarding board/mentor approval, or have been brought up before. Please share your thoughts. Also, please review the ASF graduation documentation and bring up anything else which might be a concern. Status File: (https://svn.apache.org/repos/asf/incubator/public/trunk/content/projects/vcl.xml) This is not up to date and is missing information. Previous board reports need to be added. News items need to be added containing the string new committer. Doing this will cause the numberCommittersNew column on the Status of the Clutch page to turn green (http://incubator.apache.org/clutch.html). Also, the list of commiters in the status file and project page hasn't changed since Apache VCL started. The new committers obviously need to be added. I'm not sure how the original list was decided upon, but I feel several names should be removed since they have not contributed any code and some have not been involved in the community at all. I think the list should be Aaron Coburn, David Hutchins, Andy Kurth, James O'Dell, Aaron Peeler, Josh Thompson. Also, Brian Bouterse contributed some code a while ago. I'm not sure if he is still interested in being a committer. Diversity: ASF requirement: The project is not highly dependent on any single contributor (there are at least 3 legally independent committers and there is no single company or entity that is vital to the success of the project). This issue has been raised before. I feel we meet this requirement and that the community is generally diverse, can govern itself, and be self-sufficient. Website: This is not necessarily a requirement for graduation but I feel that it should be addressed prior to graduation. Our website/documentation is pretty rough and really should be redesigned. I'm guessing the board members will look at it prior to voting. In addition, there will likely be a press release if/when we graduate and website views will spike. This shouldn't hold up the graduation process, but I would like agreement that this should be completed by graduation.

RE: icon on the desktop access to VCL
I think this question was sparked from my idea. I was wondering if an VCL image could be used as a virtual desktop via PXE boot or some other boot process. After reading the posts, I might want to rethink that due to security reasons. I do like the aspect of having an basic image on the PCs with nothing but Office, virus protection, and an VCL icon that an user would click on and authenticate with the credentials they used to login into the lab computer or Shibboleth.

Would like for process that installs the icon to also install whatever other software is required to run the app (or ensure the other software already installed). e.g. ssh client and maybe X Windows server for Linux based app, or RDP client for Windows based app, etc. Also, I believe that to support icon on desktop type launch there would need to be reasonably high assurance that an instance of the app would be available. Would like to be able to specify that minimum of n instances of an app should be kept ready for new reservations - when available number falls below n AND idle resources are available (where idle would not count instances of images that are there to meet minimum requirements) reclaim an idle resource and load another instance of the app. Generally I expect n=2 or even n=1 would be sufficient to ensure app instances available. -Eric On Feb 8, 2012, at 11:56 AM, Josh Thompson wrote: I've been hearing interest in an icon on the desktop type of access to VCL. The idea being that you could have some kind of broker script/app that can be run which will interact with the VCL API to create a VCL reservation, wait on it to be deployed, and then connect to the reserved system (ideally without requiring the user to log in to the reserved system). That app could then just be launched through an icon to gain access to a VCL provisioned system. Several years ago, I wrote something along the lines of this in python/tk. That was more of a proof of concept and would need a good bit of work to be useful to others.

Here is one way I can suggest that can be done without any modification to the current code base. You would need to write a small app that would interact with the VCL XML RPC API. The app would need to prompt users for their VCL credentials, which it would need to cache in RAM. Then, it would get a list of the environments the user had access to. The user could then select which environment was desired. The app would then make the reservation, wait for it to be ready, and then connect to it. This would be best done under linux where rdesktop could be used which allows for passing the RDP password via the command line. The biggest problem I see with this method is the API doesn't currently provide a way to get an estimated load time for a given image. So, the user wouldn't have any way to know if the selected image was preloaded or if it was going to take 20 minutes to load. Adding this capability wouldn't take much work, but it just isn't currently there. I wrote an app that does some of this a few years ago. It is in python/tk and is more of the icon on the desktop concept. I can try to dig it up if you're really ready to pursue this.
