I have to install VMWARE ESXi 5.5 as a Virtual machine on VMWARE 9 workstation. VMWARE 9 workstation is installed on windows 10 (64 bit OS). This is like nested virtualization.

However the virtual machines that will be running under VMWARE ESXi 5.5 will require 4 GB of RAM (64 bit OS). For testing purposes I will run one VM under ESXi with 4 GB of RAM. I have allocated 9GB of RAM to this ESXi 5.5 which is running as VM . Now when I give 9GB of RAM , VMWARE 9 gives me warning like this

32-bit host operating systems will be unable to power on virtual machines with more than 8GB of RAM.

Can someone please tell me what exactly this means? Is there anything I should be caring ? Please help and clarfiy



VMware ESX(I) is a a bare metal virtualization application. It does not install inside VMware Workstation. It installs directly on a machine and replace the operating system on that machine

  • For those like us who dont have bare metal server how would they practice ESXi ? VMWARE community has already published KBs on how to install ESXi under vmware workstation. – NABEEL NASIR Dec 22 '19 at 20:31
  • Please follow this guide from vmware kb.vmware.com/s/article/2034803 – NABEEL NASIR Dec 22 '19 at 20:32
  • It is only for testing and not supported in a production environment which is why my comment. The article is quite old and VMware Workstation V9 is long out of support as well. However, please let me know if you would like me to delete my answer – John Dec 22 '19 at 20:36
  • The article was last updated on 9/25/2018. :) – NABEEL NASIR Dec 22 '19 at 20:39
  • I would be glad if you answer my question about the warning message. Thanks – NABEEL NASIR Dec 22 '19 at 20:49
