Just applied update Build: 82664 ESXi 3.5 and now I'm only able to start one VM. I have tested changing the settings to see if I could launch one additional VM, but I am unable. The error message in the subject line is all I get.
Well if you increase the memory limit, the VM settings are set to automatic with no reservation, and you increased the reservation limit, then maybe you are over your memory size commit from the resource pool or the cluster. Try moving the VM to the root of the cluster (not assigned to ANY pool) then try to power it on and see what you get.
Thanks for all your help with with this ...
This is a single server, so I don't have many options. Not running VC. Good thing this is a lab server. That part that is most interesting is I only get this issue after 1 vm is running. I have started other VMs which start but as soon as I go to the second vm it fails.
Check the resource settings on your virtual machines. I've seen in my scenario, that the CPU and Memory resources, somehow, now included limits/reservation changes. They havent' caused me any problems yet, but they may be doing so for you.
I'm having the same issue. The physical host has "only" 1GB of RAM but the two small Linux VMs I'm trying to run concurrently are only configured for a mere 64MB each. I can start either one by itself but they will not run concurrently. With one VM running the physical host summary shows only 422 of 1021 MB in use, so I'm really surprised that another rinky dink 64MB machine can't start when 500+ MB shows available. I'm new to ESX so perhaps I'm just missing something, open to any insights.
What sort of values do you show for memory on the Resource Allocation tab. If the memory reservation is low, you can squeeze some more by modifying the VIM memory reservation (configuration \ system resource allocation).
Dave, appreciate your helping us. Here are some of my screenshots. The host resource allocation tab only ever shows 100 - 101MB memory reservation even though the summary screen shows considerably more than that available. I have never set that, not on purpose anyway, and cannot find a corresponding setting to change it.
