Hi all, Is anyone running FreeSWITCH virtualized (xen or vmware) in production? I saw ec2 and xen mentioned a few places. If so, are there tips or tricks for handle timer issues which affect virtual machines in general, such as recommended divider or clocksource settings? I'm seeing funny timing issues while testing with audio recording and playback that speed up or slow down. I have tried both paravirt and hvm. The default xen kernel has a timer of 250, so I tried to hvm instead using the stock 5.3 kernel with the 1khz timer but didn't see much improvement. All of this was tested on 64-bit CentOS 5.3. - Physical host: Linux localhost.localdomain 2.6.18-164.11.1.el5xen #1 SMP Wed Jan 20 08:06:04 EST 2010 x86_64 x86_64 x86_64 GNU/Linux CONFIG_HZ=250 - Paravirt host: Linux localhost.localdomain 2.6.18-128.el5xen #1 SMP Wed Jan 21 11:12:42 EST 2009 x86_64 x86_64 x86_64 GNU/Linux CONFIG_HZ=250 - Hvm host: Linux localhost.localdomain 2.6.18-128.el5 #1 SMP Wed Jan 21 10:41:14 EST 2009 x86_64 x86_64 x86_64 GNU/Linux CONFIG_HZ=1000 I'm sure physical hosts are the de-facto best practice, but are virtual machines not worth it at all?

I tried tdm400+xen DOM0+asterisk years ago, on a single processor machine but gave up. zttest returned good results, but analogue quality has intermittently very poor quality and it made telephone conversations difficult to understand. Especially a problem when hourly cron jobs would start on all VMs at exactly the same time, but was a problem at other times too. Plus the fact people who used the phone more often then me didn't report the problem, so I thought it was fine. Plus the general fact I didn't really like the idea of running Asterisk on DOM0, and running it on DOMU seemed to imply even more overheard, as DOM0 would have to process the interrupts and pass them to the DOMU. Unfortunately I don't remember what scheduler I used, maybe sedf? I suspect a multi-processor system would be a lot better suited for the task. Also might be OK if you don't use zaptel hardware... I seem to remember these cards generate a huge number of interrupts. While this was with Asterisk, I suspect my results were not specific to Asterisk in anyway. -- Brian May <brian@microcomaustralia.com.au>
I suspect you would be better off with some virtualization platform more like OpenVZ ('containers' rather than VM's) - and probably without any hardware installed (ie SIP to SIP - leave the gateways to a different part of the network). We've run some Asterisk instances in Proxmox ( http://pve.proxmox.com/wiki/Main_Page) and while it's early days, it looks pretty promising.

I second that, do not use VMs. I run tens of asterisks under linux vserver on the single box, no issues. I do not expect FS will behave differently under vserver. On Wednesday 03 March 2010, Brent Paddon wrote:

Hi Rob, We run FreeSWITCH on AWS' EC2. A medium EC2 instance is happily supporting 100 Polycom users, conference bridges etc. Been running for over a year. We also use FlowRoute as our PSTN->SIP Interface, and also Skype Business SIP. Our users are scattered across the globe - so having the box sitting on AWS' network infrastructure is key to avoiding issues with latency, jitter, packet loss (i.e. I don't think we could afford the connectivity AWS gives us if we had to provision this in-house). There were no special tricks; you do need to modify/override the following with the box's Elastic IP (EIP). modify conf/vars.xml and update <X-PRE-PROCESS cmd="set" data="domain=<YOUR DOMAIN HERE>"/> <X-PRE-PROCESS cmd="set" data="default_provider=sip.flowroute.com"/> <X-PRE-PROCESS cmd="set" data="default_provider_username=<USER>"/> <X-PRE-PROCESS cmd="set" data="default_provider_password=<PASS>"/> <X-PRE-PROCESS cmd="set" data="default_provider_from_domain=flowroute.com"/> <X-PRE-PROCESS cmd="set" data="default_provider_register=true"/> <X-PRE-PROCESS cmd="set" data="bind_server_ip=<AWS EIP>"/> <X-PRE-PROCESS cmd="set" data="external_rtp_ip=<AWS EIP>"/> <X-PRE-PROCESS cmd="set" data="external_sip_ip=<AWS EIP>"/> <X-PRE-PROCESS cmd="set" data="outbound_caller_name=<YOUR NAME>"/> <X-PRE-PROCESS cmd="set" data="outbound_caller_id=<YOUR CID>"/> conf/sip_profiles/internal.xml <param name="aggressive-nat-detection" value="true"/> <param name="multiple-registrations" value="true"/> <param name="ext-rtp-ip" value="$${external_rtp_ip}"/> <param name="ext-sip-ip" value="$${external_sip_ip}"/> <param name="NDLB-received-in-nat-reg-contact" value="true"/> <param name="NDLB-force-rport" value="true"/> <param name="NDLB-broken-auth-hash" value="true"/> <param name="enable-timer" value="false"/> conf/sip_profiles/external.xml <param name="aggressive-nat-detection" value="true"/> <param name="ext-rtp-ip" value="$${external_rtp_ip}"/> <param name="ext-sip-ip" value="$${external_sip_ip}"/> <param name="NDLB-force-rport" value="true"/> conf/autoload/switch.conf.xml <param name="rtp-start-port" value="16384"/> <param name="rtp-end-port" value="32768"/> Cheers, Chris. -- RightScale, Inc. -----Original Message----- From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Rob Forman Sent: Tuesday, March 02, 2010 9:05 PM To: freeswitch-users@lists.freeswitch.org Subject: [Freeswitch-users] Virtualized FreeSWITCH Hi all, Is anyone running FreeSWITCH virtualized (xen or vmware) in production?

Chris, I know can be more work, but the best would be to let know the differences too, and how it would be using bare bone AWS. That's also good for your employer, if he decide to switch back from RightScale... :)

Do you have your kernel timer set to higher than 1 kHz? You may experience audio problems. "You may experience audio problems." Seems pretty clear. Can that just be ignored?

We use a 256mb xen vm for customers hosted pbx platforms for up to 20 users. Everything is fine re conferencing and voicemails etc. We also use the -vm flag and this is driven by FusionPBX Each customer gets their own vm so not much load. Thanks, Gavin.
