Hello,

I installed vmware hypervisor and the license is as follows:

1)VMware vSphere 5 Hypervisor Licensed for 2 physical CPUs (unlimited cores per CPU)
Does this mean only 2 physical cpu are allowed on host
2) Up to 8-way virtual SMP
What does this mean acutally

When I assign cpu's to vm i see two options:
1)Number of virtual sockets
2)number of cores per socket

which one I should go for here

Limitations are as per below (Esxi 5.5 and I believe same applies to 6.0):

320 Physical CPUs
4 TB of Memory
16 NUMA Nodes
4096 Maximum vCPUs
62 TB VMDK virtual disk support
16 GB fiberchannel

Hi

For the free version of ESXi (not in evaluation mode, but after you have entered a free serial number) there is a limit of 2 physical CPUs with unlimited cores.

There is no hard limit of RAM. This used to be 32GB in 5.1.

As far as your question of what you should assign to VMs, it depends on the guest OS and applications that you will install and whether it makes better use of sockets or cores.

That's the Virtual SMP you asked about (8), but it also depends on the guest OS. Most OS's don't have any limits. But usually there is no need to assign more than one virtual CPU to a guest. The default setting is usually the best.

Oracle Linux, as far as I know is an example of an OS that does have limits on the number of Virtual CPU's you can use (or it gets more expensive when you exceed them).

Hi,

I got 2 physical cpu with 8 core each making total 16 and as hyperthreading is active its shows logical cores as 32.

So now i can assign total 32 cores to my guests right

Your first post clearly says 8-way virtual SMP
8 vCPUs per VM.
Hyperthread is not a core.
