Virtualized FS works great for us. Date: Mon, 20 Feb 2012 15:31:10 -0500 From: bdfoster@endigotech.com To: freeswitch-users@lists.freeswitch.org Subject: Re: [Freeswitch-users] Virtualized Freeswitch? I run freeswitch on both bare metal and OpenVZ containers. Other than occasional choppy audio I don't have issues on virtualized nodes. I suggest making sure your host is in fact set up properly. I've actually had better results using freeswitch than asterisk on the same host. There are white a few people out there running FreeSWITCH on virtualized nodes with favorable results. -BDF P.S. As with Asterisk it's not really recommended to run FreeSWITCH in a OpenVZ container. Works well enough if you bypass media.

It works great with a bit of tuning. I'm starting to work more with Freeswitch, and as such, I'm looking to implement it in a virtualized environment. My initial installation was onto a CentOS 6 OpenVZ container. However, the logs are showing this (many times): 2012-02-20 18:43:51.846882 [WARNING] switch_scheduler.c:114 Task was executed late by 280 seconds 1 heartbeat (core) 2012-02-20 18:43:51.846882 [WARNING] switch_scheduler.c:114 Task was executed late by 260 seconds 2 check_ip (core) 2012-02-20 18:46:21.496538 [CRIT] switch_time.c:798 Virtual Migration Detected! Syncing Clock 2012-02-20 18:46:21.496538 [CRIT] switch_time.c:810 If you see this message many times try setting the param enable-clock-nanosleep to true in switch.conf.xml or consider a nicer machine to run me on. I AM *FREE* afterall. I completely understand the issue with realtime applications such as VoIP in a virtualized environment with limited timing facilities. However, OpenVZ makes use of a shared kernel which in my prior experience, does not have the issues associated with fully virtualized technologies like VMWare, KVM, Xen, Hyper-V, etc. Am I incorrect or is this issue specific to Freeswitch (but apparently not so in use with Asterisk) ? There are a couple of wiki entries [1][2] which seem to indicate others are using Freeswitch with OpenVZ with success. Am I mistaken? Looking for some pointers if you can lend some insight into this issue. Maybe the errors are harmless? I have not actually pushed any traffic through this installation yet, due to the errors.
