[Freeswitch-users] freeswitch on ubuntu VM on hyper-v

I just need a little advice setting up a freeswitch VM box shared with a
http VM on hyper-v host and was wondering whether there are any gotcha's
that I should be aware of.

I expect about 50 devices to be registered on it at any time and not
expecting a high volume of calls.
It will be a fairly low spec dual core machine (dell sc1425), with 8gb ram

Thanks in advance for any advice.

You will likely have audio distortions. OpenVZ or Xen virtualization should do a better job (myself, I run two production servers under XEN and never had problems with audio quality).

Search in Google for FreeSWITCH or Asterisk under Hyper-V, and you will see the whole spectrum of opinions, and no real detailed test results.

I would have to say that one can expect audio distortion issues is just
not true anymore.

With the new Hyper-V integration code present since the 3.5 and 3.8
kernels which Ubuntu 12.04 and 13.04 uses, the Linux kernel can use a
synthetic clock source that Hyper-V provides just like KVM does. Even
the CentOS 6.4 kernel uses a synthetic clock source too as the guys at
Red Hat back ported a lot of changes from the upstream Hyper-V code back
to their kernel.

If the synthetic clock source doesn't work out for you, there is always
the good old mod_timerfd to fix issues like this.

The only (silly, rhetorical) question is, who in his own mind would run a Windows server to host Linux VM's :-))

Thanks for the advice, I have used hyper-v for http server and spam filter
and have not had a problem yet, so just nneded to make sure FS would not be
a problem.

Hyper-V virtuals are very friendly to any OS running FS. You should have no problems, just make sure you are using the native network adapters, not the emulated ones.

And if you think it kicks ass on your current system, just wait till 2012R2, this Oct 18. You should see how FS performs on a new Generation 2 VM!

That is 100% not true. Have you actually tried it yourself? The only Hypervisor that I have never had any timing issues on guest OSs is Hyper-V.

There were some problems in the HV-Versoin 1 days, but V2 and up, no problems any guest OS.

If you are using linux on Hyper-V, you should not use kernels older then 3.5. This is whan Microsoft started commiting all the HV-* modules directly to the kernel repos.

Just so you know, I have real production (carrier class) workloads on FS running on HV at a number of client sites. Peak loads process more then 1500CPS at one of them.

If you run into problems feel free to contact me off list, for some help.

Dave, nice to know that it is possible and thanks for your offer. I hope to
use it to provide small scale virtual pbx to a few clients. Will start
building the FS box in a couple of days.
