What I have done to try to spread the load is to stagger the
assignment of VMs.  For example, if you have 5 ESXi hosts and 15 VMs:
host1 - vm1, vm6, vm11
host2 - vm2, vm7, vm12
host3 - vm3, vm8, vm13
host4 - vm4, vm9, vm14
host5 - vm5, vm10, vm15

Also, vSphere 4.1 does not have limitations that impact most current
hardware but you should be aware of the vSphere 5.0 licensing
limitation of 32 GB of total RAM assigned to VMs per host.  The good
news is that VCL 2.3 will fully support KVM.  :)
