How to run vSphere in a 4 GB memory Laptop
You all know that it is possible to install ESX 3 or ESX 3.5 in a Laptop running VMware Workstation. The vSphere did not went out yet, but Duncan Epping from Yellow-Bricks has found a way to run vSphere in a VM.
Basically what’s happening is that you receive an error after the re-boot if you install vSphere in a VM (you must give at least 2 gigs to this VM, if not the installer will not even start) . Duncan has found a way arround this problem, so he is able to run vSphere on 4 Gigs laptop with 2 ESX and vCenter. I don’t know what OS he is running on his laptop. I’d guess it’s Vista 64bits or XP 64bits, to be able to fully use the RAM. I’m running 64bit Vista on my laptop with 4 GIGS as well… So I’ll try installing as soon vSphere will become available… -:)
What are the steps needed do avoid this error?
01.) Open NANO and edit this file: “nano /etc/vmware/init/init.d/oo.vmnix”
02.) Change this line: “RequiredMemory=2064384″ for your value… and reboot the VM
03.) Then just stop your virtual machine and change it’s memory, then start it again.
