Openmeetings 1.6 RC1 VMWare appliance (using Ubuntu Server 10.04 LTS)

[Diogo Coelho]

I found a VM with Openmeetings installed.
Hope it helps!

Thanks Diogo,

I have slightly modified the wiki/installation with the links:

Can this actually be done on a vm? I've been using a dedicated server because people used to say it wasn't worth doing on vm because of the realtime requirements. Assuming beefy enough hardware and resources to the vm, what could one expect in terms of simultaneous users? Anyone have any input based on their own usage.

Hi Mike,

performance hardly depends on VM VS dedicated server. It is just often the case that people rent a cheap VM for 20 Euros /Bugs and then find out that they have no SWAP space, not enough memory et cetera and no chance in changing that with their cheap VM package as they have no control about the Server that hosts all the VMs and manages the HW resources.

If you have a scenario where you actually have the full control about the VMs, virtualization has the same pro's and cons like with any other application and you can calc the IO or number of simultaneous users same like on a dedicated server.

Absolute numbers depend on the use-case.
Around 500-1000 simultaneous users for 4GB RAM, 3 GHz CPU.

I don't rent, I own the infrastructure so can dedicate hardware. Most of my blades are minimum dual duo-core 2.4 and up with 8 to 16GB of memory. Based on what you mention below, sounds like I have plenty of power.

The problem is that even in testing sip servers for example, we've come across plenty of timing issues where the clock would skew and become a problem so have since avoided anything which is real time such as sip or audio/video.

This is why I thought it was interesting when I saw this thread as I most definitely like to use VM's when possible because of the benefits in maintenance.

Sounds like you don't have any concerns using OM on VM's so I think I'll give it a try. I tend not to overburden blades when doing this because hardware is cheap, complaints aren't.

Thanks for the input.

Asterisk used to have these issues with reviving faxes. I've heard this is resolved in recent versions.

That said, I haven't really noticed any issues with voice in voip vm systems. There might be sync issues if you record a meeting on a vm - don't know.

I pay for a vps from a company that runs kvm though I haven't gotten into most of the features.

[Mike]

I too run a vm based fax server and haven't had any problems but then it's very low use too.

Anything special to take into considering when buildin OM onto a virtual machine?
I ask because the thread mentioned a virtual appliance being available but I'm not clear on the benefits over just building it myself.

Thanks.

*the thread mentioned a virtual appliance* => for VMWare ... VM and VMWare are two separated things, at least for me. A VM can be also XEN or whatever you use for virtualization, it does not need to be VMWare ...
anyway... If you are a Sys-Admin yourself you might consider setting it up on your own or hire somebody that does it, if you want to establish a reliable service you need somebody who spends 1-2 hours per month to take care of needed sys-upgrades et cetera.

Deploying OpenMeetings on 64Bit Debian or 64Bit Ubuntu on a XEN Server for example is what we have done several times. It is a bit more complex as a simple dedicated Server as the 3th party tools often need to be compiled manually for each Virtual Instance as there are no ready / up-to-date packages in the official repositories, but it is of course possible.

Sorry, I'm a general knowledge person but yes, I mean esx and yes, I admin quite a number of servers myself.
I have also used others such as Xen and VirtualBox mainly.

I've built OM on esx several times for testing, I didn't come across any complexities. Is there something I should know about, a document or something? Everything went without a hitch. In fact, I'll be building one this afternoon based on this conversation.

My OS of choice is Centos/RHEL though I've used Ubuntu because it seems to be a better OS when it comes to media based services, and perhaps even in this case?


Thanks for any heads up you can provide.

The only complication I am aware of is that you might should consider build SWFTools and FFMPEG from source (to get the latest version and libmp3lame enabled) on 64 Bit virtual Debian, that was for example a tricky thing for some of our customers. But actually if you are used to deal with source building it is no big deal.

Ubuntu has the advantage that it seems like their build in packaging is a bit more up to date with latest packages of 3th party tools. The rest is much more up to personal preferences.

No problem, I do this for all of my media based web servers so could even just use a copy I keep on hand as a starting point to provision new web servers. Sounds straight forward, I'll pull a system together and try it out.

Thanks very much for the input.

Hi

The appliance referenced in the first email from Diogo was built by
me, I made this often, not yet for the 1.7 version I'm afraid. The
idea is to be easy to anyone to try openmeetings without all the
issues of platform / components / versions compatibility, it is just
starting the virtual machine and that's it. For example, running
openmeetings on Ubuntu Server 11.04 64 bit is not just to run some
apt-get commands and go, you have to build some packages from source
because they are not available, etc (for example swftools). I've even
used one of the previous VMs I built on the company where I work to
have an easier way of communicating between our different geographic
sites, our IT support guys put it temporarily running on their ESX
VMware platform. Now they supply a service based on Scopia, so "my" VM
is not used anymore - one nice thing about Scopia that I can't compete
with Openmeetings is the integration with other videoconference
systems. We have several videoconference rooms with Polycom hardware
videoconference systems, and we are able to interact with these
systems in our PCs through the Scopia service.

Best regards

Fernando

I've not looked at it but thanks for making it available. I've not had any problems with centos to date but I had thought it might be better to use Ubuntu.

When I first wanted to look at om's abilities, I spent ~30 min Googleing for an appliance and found none. So this would've been nice for my purposes (just a few weeks too late - oh well),

Hi,

 

I have the OM appliance running in productive use. It was realy helpful getting started without the trouble setting up the system.

 

A little problem with the 1.6 RC1 alliance was, that entries in the  /etc/resolv.conf directed to servers in Portugal  (212.113.164.6) and Costa Rica ( search fgomes.ath.com). So ssh access was verry slow.

When I changes this entries to local values the system performed well.

 

@ Sebastian: An 'official' vmware appliance of the new releases would be a great thing.

 

Greatings
