Does VMware support the 64GB RAM memory kernel?
The 64GB-SMP-Kernel is not supported in VMware Workstation. This kernel uses 36-bit addressing and three-level page tables. VMware kernel code and monitor currently uses 32-bit addressing and two-level page tables, which limit it to 4GB. For a list of supported Linux host kernels, see the system requirements for your product. Note that this does not apply to ESX Server, which has it’s own kernel.
