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.

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!
