EVC is a very useful VMware technology, especially for our clients who upgrade or add new servers ad-hoc. However, determining the correct baseline has always been a bit of a pain point until I found this KB article:

For quite a few monitoring tools (i.e. VMware vCenter), there aren't any options for mail authentication. To get around this on your Exchange server, you'll need to do the following:
Open the Exchange Management Shell are run the following:
> New-ReceiveConnector -Name "Anonymous Relay" -Usage Custom -PermissionGroups AnonymousUsers -Bindings [serverip]:25 -RemoteIpRanges [ranges]
> Get-ReceiveConnector "Anonymous Relay" | Add-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights "Ms-Exch-SMTP-Accept-Any-Recipient"

I was having a strange issue where live migrations were failing intermittently with a couple of errors:
A general system error occurred: Failed to start
migration pre-copy. Error 0xbad003f. Connection closed
by remote host, possibly due to timeout.
A general system error occurred: Failed to start
migration pre-copy. Error 0xbad004b. Connection reset
by peer.
It turns out that two of the VMware hosts had the same IP set on their VMotion interfaces. Fixing this resolved the issue.
Well, Virtual Box has served me well, but now that I've completed my VCP I have a free license for VMware fusion that I was itching to play with (despite all of my licenses being assigned to the wrong person, but that's another story). It turned out to be pretty straight forward to move stuff across. My old Windows installation was running of a VMDK created by VMware converter, so a bit of new hardware detection, a VMware tools install and a reboot and we were in business. It might be just me, but it seems snappier.
I'm doing some study now for my VMware VCP. And I'm wondering what people do for cheap hardware to have a lab setup at home. I can't see any way of doing this on the sort-of-cheap. Two 64 bit servers and a NAS/SAN don't seem to grow on trees...

ESXi Configuration Guide
At work we have our guys running on Sun Ray terminals. These connect happily through to a Windows Terminal Services box which handles all of the sessions. Both the Solaris Sun Ray server and the Windows 2003 Server run as Virtual Machines under VMware ESXi.
This presentation should be viewed by anyone who is setting up a VMware server where the virtual servers require guaranteed access to resources:

This is useful to implement VPS's for customers, for example...
