I have been running the release version of VMware Server 2 and I must say I am impressed. the only problems I had were with existing VM’s and upgrading the tools on them. And also VM’s that have open-vm-tools installed.
After updating the tools the systems all have been functioning just fine over the last few weeks and the host system has been under less load with more vm’s installed.
I might create a post on how I did it , but work is taking a load of my time and so that will have to be later.
I did try the new ESXi server but my hardware is not supported and I don’t have the cash to buy new stuff.
