I have a ESXi 4 host based on IBM X3650M2 and in which resides two VM(VMa &VMb)
>IBM X3650M2
4G memory
>VMa
2*vCPU
2G memory reserved
In my mind,besides the overhead memory,there would be about 1G left for VMb
But when I allocated memory to VMb,there is less than 100MB memory that can be reserved for VMb
I checked the configuration of the host through VI client,in the Allocate Resource Tab, I found the "Total Cpacity" of the host's Memory is 2305MB,
Does that mean , in a total amount of 4G memory there are only 2305Mb memory left for the VMs, and the overhead memory is about 1.7G?
If it is ture ,the overhead is considerable
Several users reported that and I noticed it myself on esxi 4.0. You might wont to have alook at this one:

ESXi 4.0 requires 2GB for itself only, so in you case you should add more memory or think about ESXi 3.5.
