Can a virtual machine (vm) have more ram allocated than the esxi host physical memory?

Yes but you will need enough disk space for the swap file.








Example:
Host has 32GB physical ram











Yet the vm has 64gb allocated to it















If you don’t have enough swap space you get this error:









Here 1tb of ram was allocated to the vvm.
I don’t have 1tb on the store nor do I have 1tb or ram.
So it couldn't power on.
