I'm crazy enough to run FreeSWITCH on the Rackspace cloud. They allow you to build your own kernel, so I have a custom one with 1kHz interrupt timer. Seems to work fine.<br><br><div class="gmail_quote">On 20 February 2012 20:37, Peter Olsson <span dir="ltr"><<a href="mailto:peter.olsson@visionutveckling.se" target="_blank">peter.olsson@visionutveckling.se</a>></span> wrote:<br>

The log lines indicate that the monotonic clock in the OpenVZ container goes backwards by the time it's logged. I haven't used OpenVZ much though, so I'm not really sure what could be the reason for this.<br>

Ämne: [Freeswitch-users] Virtualized Freeswitch?<br>
<div><div><br>
Greetings all-<br>
<br>
I'm quite experienced with Asterisk, and specifically, usage in a virtualized environment. 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):<br>
<br>
2012-02-20 18:43:51.846882 [WARNING] switch_scheduler.c:114 Task was executed late by 280 seconds 1 heartbeat (core)<br>
2012-02-20 18:43:51.846882 [WARNING] switch_scheduler.c:114 Task was executed late by 260 seconds 2 check_ip (core)<br>
2012-02-20 18:46:21.496538 [CRIT] switch_time.c:798 Virtual Migration Detected! Syncing Clock<br>
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.<br>
<br>
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) ?<br>
<br>
There are a couple of wiki entries [1][2] which seem to indicate others are using Freeswitch with OpenVZ with success. Am I mistaken?<br>
<br>
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.<br>
<br>
Thanks!<br>
<br>
