Hey Everyone,
I have my home Asterisk (Rpath, poundkey) running in a VMware
Server environment, hosted on CentOS, with three other VMs.
(My IPCOP Firewall, a Fileserver, and SSL Explorer) All 4
VM's run nicely on a P4D with 2GB of RAM. I have disabled X
on the Host, and My Host only shows about 10% usage at peek.
Idle it shows almost none, and when I am only placing calls
(no other VM's in use) the pound key VM shows 5% and the host
shows less.
I have 4 Cisco 7960's registered, and Sipphone, FWD,
Sipbroker, my office (via IAX) and Vitelity all registered
for trunking, and 2 ATAs for POTS.
All accounts and devices stay registered, and work without issue.
I think its important to remember that unless you are
transcoding between codecs your Asterisk server doesn't do a
whole lot. If you stay ULaw for example on all of your
devices, Asterisk really is just directing traffic.
However, and I cannot stress this enough, MS Windows is a
poor VMServer platform when it comes to resource usage.
Vmware and Virtual PC are forced to fight the Windows Host OS
for resources.

We are running on two virtual servers, one on Xen, one
on VMWare ESX, both
have perfect sound quality. We don't have any hardware
cards, pure SIP, and
had used different codecs, including g711, g723 and
g729 with no issues. We
have around 10 people concurrently using the system.
With that said, Jim you have a point, Windows is not
the best host for
virtualization. Both our environments are based on Linux.

What you are proposing might work as a development
system (I'll admit that I
have not used Virtual PC, but I use VMWare
extensively), but regardless, you
would not want to put such a system into production.
Asterisk requires
priority access to the CPU, and as such, it is hard to
imagine any kind of
virtual machine being able to run it in a manner that
delivered proper sound
quality. The Asterisk software will actually run
well-enough, but the sound
quality is going to be poor, even on a powerful system
with the Virtual
machine running at high priority. Even if it could be
tuned to deliver
proper sound quality, you would still never be able to
predict when some
windows background task would steal a bunch of
resources. Windows likes to
go off and do its own thing, and when it decides to
perform some background
task, it is quite capable of hogging resources such
that your asterisk
system will deliver terrible sound quality.
If you want a low-cost platform on which to run a small
asterisk system,
look to something like the Linksys WRT54GL (OpenWRT).
If you need FXO, grab
something like a Linksys SPA3001. You'll be able to run
a phone or two on
that with no problems.
Virtual machines are awesome for development; asterisk
runs perfectly.
Unfortunately, the sound quality is generally terrible.
Not such a problem
in the lab, but a show-stopper in production.
Jim

I have just upgraded to a new system, and
managed to get high
speed in the country (Hello WiMax), with that I am
experimenting with Microsoft Virtual PC.
I like what I've seen so far and want to reduce desktop
clutter, and floor clutter by combining most,
if not all PC's
into one unit. Has anyone had any experience running
asterisk under Linux in a Virtual PC environment?
Windows Vista Ulitmate, with Virtual PC 2007.
Generic X100P (I think) PBX card.
2 GIG Ram, soon to be upgraded, with 250 GB
SATA3 Seagate...
Slackware 10
Asterisk 1.4(?)
Any suggestions would be appreciated.
THANKS!
