If the other hosts don't have enough capacity for moving the VMs, then you only have one option: schedule downtime for your least important VMs and shut these down. This should allow you to take down one host and keep the essential VMs running.

Hi,

For memory: Technically, this can be done.... provided you did not configure reserve memory for the VM. However, this will HIGHLY impacting the VM performance, as all the VM are fighting for memory.

For Disk space: If you are using Shared storage across the four host and all your VM is reside in the shared storage, then whereever you shift the VM to other host, the storage will be remain the same.
