Hi,
I've come across this really strange problem within the VMWare environment I manage.
Some of our Windows 2008 VM's are flagging that their hardware has changed and now the product needs re-activation - but i've not changed anything (that i'm aware of). It's really frustrating as i've had to purchase new licenses to resolve this issue.
We are running ESX 3.5 U4 and have once cluster made up of 12 hosts. EVC is enabled because 6 of the hosts have slightly different spec CPU's.
Comments appreciated.
