To get the best performance from my VMs I like to allocate the entire disk size, and also make sure the publisher runs with at least 2GB of RAM (but we have a giant ESX setup). You'll be thankful for this when you're not waiting 30 seconds for each CCMAdmin page to load.<div>

I setup a few CUCM7s in workstation and configured them to dynamically
allocate the disk space. After the initial install I recall the VM
took up around 15-20 GB of diskspace on the host machine. After
leaving the CM7 VMs running 24/7 for a month or so, the size of the VMs
grew to somewhere around 40-50 GB due to log files, etc. This was in
a small lab environment with very little active call processing.<br>
<br>
At least these are the numbers I recall, I no longer have the VMs to
verify the size. Keep that in mind when you're planning out how many
VMs you can fit on your host machine.<br><font color="#888888"><br>Justin</font><div><div></div><div class="h5"><br><br><div class="gmail_quote">On Sat, Aug 1, 2009 at 10:29 PM, Lelio Fulgenzi <span dir="ltr"><<a href="mailto:lelio@uoguelph.ca" target="_blank">lelio@uoguelph.ca</a>></span> wrote:<br>
