Re: [Freeswitch-users] Running FS on a heavy loaded VMWare host
It is important to define heavily loaded host... What is loaded - network, CPU, RAM, I/O? If you cannot guarantee enough resources for new FS VM probably you will have troubles. Best advice will be to try it yourself. One general tip for optimization - do not assign more resource to a VM than it actually needs.

Hello,
I’ve been going through some threads about virtualization, some say it works for them, others say it doesn’t. Multiple platforms are used like MS Hyper-V, VM Ware, etc.
We currently run FS on a physical box, which works great.
We have our own virtual environment, VMWare vSphere 5.0. Our 5.0 environment is running under heavy load and I was wondering would FS (configured properly for correct timing) still function properly and able to handle hundreds of concurrent calls on a heavy loaded VMWare host? The FS virtual will also process RTP in default mode. I was hoping if someone had any experience using this setup and could give me some insights on this matter. The FS virtuals will function only as SBC’s, so no complex dial plans, no call recording, no conferencing. Just bridging the incoming call leg with an outgoing one.
VMWare has a tech paper about running VoIP on their virtual machine, and they claim it works. (http://www.vmware.com/files/pdf/techpaper/voip-perf-vsphere5.pdf). In the paper they used Mitel vMCD, but I’m not sure if the software has been optimized to run on VMWare so the tests would come out better than running any other telephony software like FreeSwitch or Asterisk.

Can you tell me why more resources isn't good for optimization? Do you mean to make efficient use of bare metal?

FWIW, I thought only CPU and memory would be relevant when virtualizing a basic FS instance (only routing calls, no fancy dialplan with DB lookups or any other I/O stuff), but heavy I/O on the *host* without saturating the CPU proved to significantly degrade the calls quality. It has to be a timer issue but I have yet to find time to investigate that so for now I'm just careful when doing maintenance on our KVM hosts. As a side note I had a few problems running things on a 2-node KVM cluster with raw disks over glusterfs - I/O intensive stuff in one guest on one server would make guests on the other server almost come to a halt. I'm now migrating to DRBD to see if things improve. On 09/02/2013 03:26 PM, Richard Genthner wrote:
