How many VM's on Vmware vSphere's FREE Hypervisor

Is there any limitation on how many VM's you can/may install under the Vmware vSphere's FREE Hypervisor?

Hi, none at all; you are solely limited as "hanccocka" & "PaperTiger" stated, by your host resources. Two things to keep in mind -> 1. you obviously need to have an OS license for all your VMs (if applicable...i.e. for Windows); 2. VMware guesstimates that you can run about 4 VMs per *core*. So, given if you have a dual quad-core CPU host, you can run about 8 VMs. This also depends if you have enough memory and of course disk storage. If you enable hyperthreading in the BIOS, the amt of VMs doubles (hyperthreading basically does just that...doubles CPU processor; you can read more about it here: and here:

Hope that helps.


No. Same number of vm's that can run under the paid one. Have a look at this. Basically with the free version you don't get the advanced features.

No limit, depends on how many/much cores, cpus, memory, disc that your host computer has, and the workload your VMs create.
You can refer to this document

I am trying to find the doc I read before. The limitation comes from the number of physical process (I think it's 6), total number of cores/process (6)  and the total amount of memory (256GB) ESXi supports.

I don't know what you want to run but for plain Windows 2008 Server Standard vms, the low estimate is that you can easily run 3-4 per core given enough memory.

sorry, typo. should be "processor" not process.
