Re: VCL image capture dies, failed to prepare vmx file
Hello Will, You will want to disable the auto-assigned mac addresses from ESX/ESXi. Part of the requirement is to run a dhcp server on the management node, at a minimum for the private management network. With that when you add new computers you define your mac addresses upfront in the add computers interface. When you add multiples you can add many at a time. Also the add computers tool, will generate dhcpd.conf entries for each node, so you can cut-n-paste to your dhcpd.conf file. Please see the Adding Virtual Machines section in this link for the detailed steps, https://cwiki.apache.org/VCL/vcl-221-further-steps-if-using-vmware.html Hope this helps.

Re: VCL: public/private IP discrepency?
Yes, in the vcl code during the post_load tasks of the OS modules. There is a step to collect the network configuration of the loaded node(vm or bare-metal), figure out the publicly assigned address and then update the database which is then presented to the end-user.

The main differences from VCL's perspective: Dynamic dhcp setting - fetch the assigned address using ifconfig or ipconfig(depending on the provisioned OS) and update the public IP address in the computer table. Manual dhcp setting- return the address assigned in vcl database, this method assumes that the address is correctly defined in the vcl.computer table. This setting will likely go away since the dynamic dhcp option is doing the right thing in confirming an address got assigned to the machine. I would like to see the manual dhcp setting go away in the future, since it's not really doing anything. We have a mix here at NCSU, our campus networking group uses fixed dhcp on campus, in another off campus DC we use dynamic dhcp. We have it set to dynamic dhcp for all of our 8 management nodes.

Hi Michael and team,
Could you share your vmware host server and vmware profile information
that you have stored in your setup? Based on the log output there
might be some missing information or it's not setup correctly.
Since this is a public list, if there are any public IP address or
anything important feel free to obscure that info or send to me
privately.

Re: VCL image capture dies, failed to prepare vmx file
ok. Then best bet is to update the computer records for the missing mac addresses. I typically use phpmyadmin or cmdline. I'm not sure what other tools are available for editing mysql db's. An issue with just deleting the computer record, is that there is also a record in the resource table that is used to reference the computer.id. This resource.id is used for computer groups and some other things. If deleting only the computer record, then it would cause other queries to fail.

Re: Graduation
Hi Dmitri, No apologies necessary. This is a good and important question. The graduation is the process in which a incubator project becomes a Top Level Project (TLP). The graduation means that a project has shown that it (as a community) understands the Apache Software Foundation's core principles. Also known as The Apache Way. While this is not a complete official list, the principles include: * collaborative software development * commercial-friendly license * respective, honest, technical-based interaction * faithful implementation of standards * security as a mandatory feature See this for more info on how ASF works http://www.apache.org/foundation/how-it-works.html My slightly longer answer. Within Apache Software Foundation there is a entry path in which a project/community shows that it, (as a whole) can be self-sustaining and operates under The Apache Way. This entry path is through what is called the incubator and this is our current state. In incubator status, we as a community, learn the principles (The Apache way) by doing. With the assistance of our mentors, such as Kevan, Alan, and Matt. We learn the core principles mentioned above, how to grow a healthy and diverse community, how to properly cut releases through Apache software Foundation, handle intelectual property through the community contributions, and learn the principle of meritocracy (government by merit) through the process of inviting community members who have contributed and are interested to become committers and be part of the project governing process, etc. Once we have reached the incubator milestones, we can then proceed to graduate. Through the graduation process an incubator project either becomes a subproject of another ASF project or a top level project. If we fail to do these tasks or if the project fizzles out, then the incubator project retires from Apache Software foundation and is not supported by ASF. Hope this helps and others please feel free to comment. Most of this is my summation from: How ASF works and short history: http://www.apache.org/foundation/how-it-works.html Incubator Graduation: http://incubator.apache.org/guides/graduation.html What is Graduation? http://incubator.apache.org/guides/graduation.html#introduction Roles of incubator http://incubator.apache.org/incubation/Roles_and_Responsibilities.html Aaron On Mon, May 7, 2012 at 8:11 PM, Dmitri Chebotarov dcheb...@gmu.edu wrote: Hi, May I ask what are the benefits of graduation for VCL?

Re: [DISCUSS] Graduation
As for the website, I agree that some design work would be really useful. I am assuming that ASF would provide a hosting arrangement, i.e. a domain like vcl.apache.org? Would that also include server space to run any type of CMS? Confluence is a nice all-in-one package, though if you are considering a complete overhaul of the site, I could also recommend a system like Drupal (MySQL + PHP). Drupal has a lot of bells and whistles that can make for a very nice, highly interactive site. The downside of drupal is that it is not specifically designed to handle software documentation. On the other hand, if we only need to serve static html pages that focus on documentation, etc, I can also recommend Sphinx. The downside of Sphinx is that it is really best for Python and C++ projects, and it doesn't support web-based updates -- it does create excellent sites, though. I believe we can run anything we like. ASF does provide the hosting and the top-level projects do have their own url projectname.apache.org. I'm not up-to speed yet on what our options are or what the other projects are using. The Apache infrastructure team is recommending projects to migrate away from confluence. Has anyone else had a chance to research which cms tools are available supported/recommended by ASF? I am also a little unclear on the timeframe for modifying the website -- it this something that would be done prior to graduation or upon graduation? I don't think it is a requirement, but ideally it would be nice to at least have a start on a new site by graduation time. Aaron Peeler

There are several requirements which must be met and steps completed in order to graduate. This discussion thread is the first step towards graduation. 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.

We have several hadoop clusters here at NCSU using this method, it's simple but seems to work well. In the future we would be better served using configuration managers like puppet, chef, bcfg2, etc. (We should put this on the roadmap.. :) ) Hope this helps.

Re: available computers
Cool. Nice script. Do you have an account under Jira? https://issues.apache.org/jira/browse/VCL If so would recommend to create a jira issue for 2.4 release to add this in. This way we can make sure to add that in. Also it may be worth looking at a script called healthcheck.pl in pathtovcl/vcl/bin. I think healthcheck.pl does not work too well in 2.2.1 - had some issues with the data structure object. The healthcheck.pl in the repo for the 2.3 is pretty stable, it doesn't initiate a reload, but checks the state of the machine, current image in db vs actual image loaded and updates the database accordingly. So maybe, we could combine yours and healthcheck.

If VCL has a bunch of availabe computers preloaded with an image and I then update that image (new image revision), computers are not automatically reloaded with newer image revision. New reservation will have new image revision, but those available computer will still have older image revision and it would be reloaded only if a user makes reservation. At that time it will take longer to load (ie. ~10min vs 1min for preloaded available computer). Also in cases when I need to reboot ESXi hosts, all the VMs are not loaded automatically. In this case database lists those VMs as available, but they are off-line. I would like to share the small tool (a .pl script), which syncs available computers with actual state of computers (VMs). I've used peaces of code from utils.php to write it. The script creates reload requests for all available computers using the current image and latest image revision. VCLD then caries out requests and reloads computers which are either have older image revision or cannot be contacted via SSH (ie. after ESXi reboot). I plan to run the script weekly via cron on vcld server to make sure all is in sync, as well as after image updates. I've tested it and it works fine. .pl is attached.

Re: Timed out reservations
In the upcoming 2.3 release, the user will be able to do this through a remove button on the current reservations page for the timed out reservations. For now, it's either the user waits until the end-time is reached or the vcl sysadmin manually removes it through the database.

Re: Vcl and vmware HA
Not is this upcoming release. With VMware HA, it's easily handled by vcenter if you have the correct licenses... With the libvirt module - this release is going to support kvm. Libvirt also supports vmware, but that would need to be added in later if necessary. The current work that Aaron Coburn and Andy Kurth have done with the VMWare prov module are fairly robust, so I'm not sure if the libvirt-vmware part is needed. On the kvm side, there would need to be HA logic built into the libvirt-kvm module. Or there would need to be a work done to talk to RHEV - Red Hat's equivalent to vcenter, but for kvm hypervisors. Others may also have other thoughts on this. It's ideal (probably needed) as we get into more server based provisioning to have HA functionality for the kvm, it would be good to start designing this part out and possibly target a later release 2.3.x .

Re: ESXi 4.1 image for VCL reservation

Re: Full desktop Linux images?
Just as a heads up, in the 2.3 release we're adding support to define connection methods on a per image/OS basis. We have a lot of the code work done and it's fairly stable in the repository. See VCL-30 and VCL-526 https://issues.apache.org/jira/browse/VCL-30 https://issues.apache.org/jira/browse/VCL-526 The basic flow would be to start the service and open the defined port in the OS level firewall.

While passwords are not sent in plain-text (as in telnet), cracking could prove successful if both the encryption key and encoded password are sniffed from a network. For this reason it is recommended that a password of at least 8 characters be used. On the other hand, there is also an 8-character limit on some versions of VNC; if a password is sent exceeding 8 characters, the excess characters are removed and the truncated string is compared to the password. However, VNC may be tunnelled over an SSH or VPN connection which would add an extra security layer with stronger encryption. SSH clients are available for all major platforms (and many smaller platforms as well); SSH tunnels can be created from UNIX clients, Microsoft Windows clients, Macintosh clients (including Mac OS X and System 7 and up) ? and many others. There are freeware applications that create instant VPN tunnels between computers. UltraVNC supports the use of an open-source encryption plugin which encrypts the entire VNC session including password authentication and data transfer. It also allows authentication to be performed based on NTLM and Active Directory user accounts. However, use of such encryption plugins make it incompatible with other VNC programs. RealVNC offers high-strength AES encryption as part of its commercial package, along with integration with Active Directory. Workspot released AES encryption patches for VNC.

Re: VCL and xCat
We use a single dhcp server/config on the private network for both the blades and vm nodes. In xCAT2 - there are globals set in the default /etc/dhcpd.conf and xCAT makes heavy use of the /var/lib/dhcpd/dhcpd.leases files for adding nodes, etc. We typically have blades that are part of the xCAT tables and vms that are not. We just add the vms to the /etc/hosts file same as the blades and just script the adding of the vms to the leases file. You could definitely add the vms to the xCAT tables - just to make use of the makedhcp cmd. But with hundreds of vm entries, that just cluttered up our xCAT tables. So we just elected to add them directly outside of the xCAT managed blades.

Re: Virtualizing the Virtualization Server
Yes, your going to need xCAT. We've have found that ESXi needs to be installed via kickstart type method using xcat. Partimage - which is the tool used underneath xCAT layer doesn't support the ESXi filesystem. xCAT can deploy using either kickstart or partimage method for x86 hardware. We are using xCAT to deploy our bare-metal environments; user created, kickstart based environments, and for our hypervisor environments ESXi, and for the next release kvm. xCAT is a very nice tool when you have more than a couple of blades to install or repurpose for other features supported by VCL. At first I would suggest to get xCAT working at the command line before trying to use xCAT through the VCL interface. VCL xCAT provisioning modules are only making xCAT system calls to install a node. Once xCAT is setup correctly and working, then start using it through the VCL interface. When you get ready we can share our esxi kickstart template to compare, so you can built one for your environment.

Re: questions regarding creating base images
No you don't need to upgrade 2.0. IMO, 2.x is more flakey than 1.x and will cause you other issues. If you were to upgrade, I'd recommend to use ESXi. First, just to make sure, are you using the VCL 2.2.1 release? If so, you should be able to fix this problem by changing the computer provisioning module to 'VMware' for each of your vmguest computers.

In 2.3, there will be the option to grant any user group access to manage block allocations for just their affiliation. I'm thinking with this option, there is no longer the need to select a managing user group for block allocations. So, I'd like to just drop the managing user group altogether. In which case, if you are in a user group having the Manage Block Allocations (affiliation only) permission, on the Block Allocations page, you'd see all block allocations owned by people with the same affiliation you have.

Re: Reserve a cluster in VCL
Yes, but with limitations. Also this is more related to your local networking setup and the individual provisioning modules. Today VCL does not dynamically create/destroy vlans when needed. I think this is needed in the long-term - at some solution at a localized level - i.e. within a DataCenter. To make it work in the current code - You would need to have the required vlans setup and preconfigured in your hypervisor, if using xcat in your ethernet switch modules(ESM). In the image table there is a column called project. At NCSU we use this project variable to define special vlans that have been trunked to the hypervisor or the ESM that the desired vcl image should be in. Within a provisioning module, one can use the project variable to define which network the vm should be a part of. Note - there is not a globally defined VCL method for handling the project variable. For example in the xcat module there is a routine called _assign2project. This routine simply calls out the a custom script (local to NCSU) to change the vlan assignments on the blade port within the related ESM. In the VMware/VMware.pm module it checks for and adds an existing network by the project name to the vm. But the network name has to be listed within the hypervisor. Look for $image_project in the VMware.pm. It would be great for the community to start researching this and designing the code to handle dynamic vlans.

Re: VCL Bootcamp notes on creating base images
The first one means you have to have computer nodes and the exsi host added to the vcl database. The vcld --setup tool pulls the target node and esxi host information from the database.

What does it mean for the computer being captured has been added to the VCL database? I can do the rest once I figure out how to do that. Perhaps a little background will help... I have installed ESXi, installed CentOS in a VM configured to be the management/web/database/DNS server as we did in the bootcamp, have configured a VM server (pointing back ESXi as per bootcamp), and have added a VM through the web interface (only one because the hardware is pretty anemic). I don't know what to do next. I think I need to create a new reservation, install CentOS and configure it as a base image, then capture it with vcld --setup. But I am not sure.

Re: VCL Bootcamp notes on creating base images
Yes Is this what your looking for: https://cwiki.apache.org/confluence/display/VCL/Create+a+Linux+Base+Image Also I see vm-1 is in maintenance mode - go to your Virtual Hosts tool on the VCL portal, select the host - click the configure host add vm-1 to esxi-host-1 The image capture process will detect that vm-1 is in maintenance mode and stop the process.

Re: VCL Bootcamp notes on creating base images
It depends. I don't recall if the image capture request out right fails and gets removed when vm-1 is in maintenance mode or not. To check you can use mysql and run select * from request; If there is a request listed in maintenance state (statid=10) then you could change the stateid back to image (stateid=16) Or you can use vcld --setup again and give it a different image name. (This is the easiest path and what I would recommend.)

Re: VCL Bootcamp notes on creating base images
You'll need to use mysql or phpmyadmin to change an active host's vmprofile. The profile is assigned in the vmhost Get the id from the vmprofile table - the VMware ESX - local storage profile is id 4 The update the vmhost table for that host. This query assumes that you only have one vmhost in your vmhost table or it's ok to change all of them: update vmhost SET vmprofileid =4; I think the restriction on not being able change an active vmhosts profile to another profile was an oversight or it was related to xcat based hypervisor installs. Regardless, I added a jira issue for it to get fixed. https://issues.apache.org/jira/browse/VCL-495 Aaron On Fri, Aug 5, 2011 at 12:55 PM, Mark Gardner m...@vt.edu wrote: OK next problem: I selected VMware ESX - local network storage originally for the VM host profile as that is what we used during the bootcamp but the paths are wrong (e.g., /vmfs/volumes/local-datastore vs /vmfs/volumes/datastore1).

Re: base image creation
Jay, Sorry - I realized I should have elaborated more on the errors in the log file. First of all welcome to the community. :) VCL with vmware provisioning can interact with the ESX(i) server in a couple different ways. The first error below is related to the vcl using the vmware sdk perl tookit, for this you'll need to set the password for the ESXi server in the vmware profile in through the vcl web interface. The second is also related to the sdk perl toolkit, from what I can tell it looks like it's not installed on your management node. The third error is related to the next method that vcl will try to manage vms on esxi, it's trying to ssh into the esxi server and run local cmds such as vmware-vim-cmd to manage the vms. This latter method is probably the best approach, if you can make sure you have ssh enabled on esxi and have your ssh identity keys setup. Then you should get further. Again welcome and I apologize for the initial short response. Aaron Peeler On 2/4/11 7:46 AM, Aaron Peeler wrote: Can you also ssh into the esxi server using identity keys?

Re: Licensing aspects of a VCL project
Hello Dave, As Mark mentioned there are some who have spent more time on this than others and I have to say there is not a clear cut answer, as your finding out one has to deal with it on a vendor by vendor basis.

I will provide you with the contact info of our NCSU license coordinator off-list and you can contact him directly .

You can contact Sharon Pitt sp...@gmu.edu mailto:sp...@gmu.edu at George Mason University who can give you more details but here is the invitation I received: /Current software licensing models can be barriers to consumer-orientated technology services. On August 11, 2010, you are invited to discuss new software licensing models that allow us to serve faculty, staff and students in innovative, improved and more cost effective ways. This statewide software summit will be held at Virginia Commonwealth University in Richmond, VA from 9:30am - 3:30pm. More information, including registration information, will be forthcoming. In the meantime, please hold the date./ I also believe that NC State has done quite a bit with licensing in the process of developing the VCL approach. You may be able to contact Harry Schaffer or others at NCSU for more information. (Sorry, I don't have any special insights into the issues of licensing.)
