Actually you do.  The vmware tools provide a replacement network and disk
driver which improve both network I/O and disk I/O by a fair bit.  I don't
run a desktop on any of my servers, but still use their toolkit.


Just my $0.02CAD ;)

I've not used VMware specifically with vpopmail/qmail however I've used it
to test and deploy a number of other apps. Essentially all you need to
really worry about is performance, particularly of IO. This is alleviated if
you use a SAN to supply your virtual disks, or if you pass through the
underlying physical disks into your virtual machine.

There are no kernel mods or changes to native libraries required for VMWare.
Its a seamless environment that looks just like a real machine to the OS.
They do supply some kernel modules for their emulated devices so that
running a desktop is faster, but I doubt you'd want to mess with those for
this application.

Hope that helps,

Subject: [vchkpw] VMware for vpopmail kit?

I have a customer who is inclined to consolidate their 5-10K users from
a couple of qmail servers onto a "high power" VMWare server.  I
understand VMWare conceptually, and have seen some minor conflicts noted
in general email threads for other products.  However, I haven't worked
directly with VMWare, so some of this concern/interest is academic.

Anyhow, I'm concerned that kernel modifications, low-level disk
behaviors, loadable modules, or "tweaked" native libraries under VMWare
might create unintended hurdles to such a setup being successful.

Anyone have any experience or advice for such a scenario?

Thanks, Dave.
