From the vmware blog:

Conclusion

A 1vCPU Xeon X5500 series based Exchange Server VM can support 50% more users per core than a 2vCPU VM based on previous generation processors while maintaining the same level of performance in terms of Sendmail latency.  This is accomplished while the VM’s CPU utilization remains below 50%, allowing plenty of capacity for peaks in workload and making an FT VM practical for use with Exchange Server 2007.

From Professional VMware blog, here is another method to fix your lost Ethernet device on Ubuntu.

Another method of doing this, is to edit the ‘persistent-net-generator.rules’ file to include something similar to:

# ignore VMware virtual interfaces
ATTR{address}==”00:0c:29:*”, GOTO=”persistent_net_generator_end”

According to this thread, if you need to use the linux-image-virtual package on ubuntu then it only supports the “bus logic” scsi controller with ESX.

Need to access the ESX console with the Virtual Infrastructure Client in some remote location where your VPN does not work.  Forward ports 443, 902 and 903 with putty.  Port specifics for ESX can be found on page 179 of the ESX Server Config guide.

In my case I additionally need to forward from a boundary machine:
ssh -L 8443:localhost:443 -L 8902:localhost:902 -L 8903:localhost:903 node2

Couple useful articles from Andy Millar.

• Concise and clear explaination of linux load averages.
• Bug fix suggestion for VMware server which can hang on installation. Remove the floppy device. I’ve got another issue where a linux vm on vmware server hangs on startup and I’ll have to try this.

Useful article on template windows vmware images. One point of great note:

As a result of point (4), your OS disk is now perfectly aligned with the storage layer below it, increasing disk I/O performance. This is actually a server OS problem that applies to all of Microsoft’s pre-Windows Server 2008 server operating sustems, and Windows XP. A simple explanation is that systems like to write data in 64k chunks onto disks with 64k sectors. However, they create their very first chunk at only 63k in size. That means every subsequent chuck writes at least 1k to the previous sector, resulting in every read and write going to two sectors and resulting in two I/Os per operation instead of just one I/O. This is what you’ve just corrected in (4).

Here are a couple useful ESXi hints:

• ESXi 3.5 does ship with the ability to run SSH, but this is disabled by default (and is not supported) – from.
• ESXi and what it does NOT have compared to regular ESX 3.5
• Upgrade ESX eval to ESXi.
• Some Basic ESXi questions.
• 8.04 and ESX.
• Motherboards and unsupported servers that work with ESX 3.5 and / or ESXi 3.5 Installable
• 
  Running ESX 3i Installable from a USB Flash Drive

.

Market is changing constantly – this is a big move on VMwares parts but follows on their previous strategy with GSX/Server and VMware player:
VMware ESXi Hypervisor Now Free – VMware
