We currently run HP DL585's AMD host servers but found out our DR site will be providing us Intel based server (make/model I am not sure of). They are responsible for installing ESX.
Would my Windows 2000/2003 guests care the hosts are now Intel (ignoring VMotion since I had to use CPU masking to get some vmotioning to work in my current environment)?
Thanks in advance!
Windows VMs normally don't have a problem with the CPU change.
An exception are application which utilize special CPU features - those apps are rare.
With Linux you will probably run into problems.
Why so? I would have thought that the linux guest would only see the VM hardware. Not trying to catch you out here Oliver, but I am interested in an explaination as Linux/*NIX is not my stong point.

Think it may depend on what linux kernel you have. If you have one compiled specific for AMD you will have a problem and would need to switch to an i386 kernel.
I had that problem where I had a linux VM installed on an opteron host and then moved it to an Intel host and had to switch kernels for it to boot properly.
