If DNS is failing you…. You can run the following powercil script to list all IP’s to virtual machines within vmware….
$IPaddresses = @()
foreach($vm in Get-VM){
$vm.Guest.VmName | %{
$IPaddresses += $_
}
$vm.Guest.IPAddress | %{
$IPaddresses += $_
}
}
$IPaddresses
Some really good info at this site : http://kennethvanditmarsch.wordpress.com/2009/11/04/understanding-hp-flex-10-mappings-with-vmware/
A bit more around his finding during some tests : http://kennethvanditmarsch.wordpress.com/2009/12/04/testing-scenarios-vmware-hp-c-class-infrastructure/
There are some really good products out there in the market at the moment…
Exinda – low cost, really good QOS / prioitisation and visibility. Falls short on acceleration (at the moment)
Riverbed – One of the key players in the acceleration market. Optimized algorithms for specific traffic.
Silver Peak – Relatively new, work well as a capture all acceleration device with QOS / prioritisation included.
One to watch – traffic squeezer. I’m always a fan of open source getting into new technologies, and this project seems to be a good start. Its still early days but I’m hopeful this will take off and become a contender in the future ahead.
A few of the above vendors actually have a virtual version of their appliance. Depending on your current investment in virtual infrastructure this may or may not be a good idea. I’m still a fan of dedicated hardware, but in some cases the redundancy provided by a virtual infrastructure can out way the potential performance gains.

Logon to SSH or console and complete the following (WINXP-12 is name of machine causing me greif)
