Maximum memory in Guest O/S

[brymills]

Knowledge Base article 1909 states that there is a limitation of 16GB of memory when installing Redhat as the guest O/S. As the hugemem kernel is not supported this seems reasonable for a 32bit installation. However, when using 64 bit Linux on 64bit hardware is the guest O/S still limited to 16Gb?

If you are going to create a VM from scratch, then you can allocate more than 16 GB. Please refer to the configuration maximums for VI 3.5:

Size of RAM per virtual machine 65532MB (64GB ‐ 4MB)

Just remember that's the theoretical max you can provide.

The maximum amount of virtual memory you can assign to a vm is 64 GB but remember if the O/S you ar einstalling cannot support 64 GB it will not be used -

It was actually knowledge base article 1901. This arrticle seems to be incorrect then?

Additional to that, if you do need to have such huge memroy for your VM, it will be better idea to keep it on the physical server

In VM environment, you will gain more perfomance if you scale the number of VM you have instead of consolidate it all to 1 VM
