how to: Installing ESXi 5.5 on less than 2GB RAM
Submitted by marafa on Thu, 2014/03/27 - 1:23am
you may know i am trying to set up an esx lab at home. i was trying to do it with nested virtualisation but it wasnt working out very well so instead i dig up an old hp 7800 desktop that i had and slid the cd in.
and it wanted 4gb or ram instead of the 2gb i had. so searching around on the internet tubes i found this article
but it didnt fit my scenario exactly so i had to edit his steps a bit
- Boot the system from CD with the ESXi installer on it.
- Once the installer welcome screen shows up, press alt+1 to go to the first console (login prompt)
- Login as root, no password.
- # cd /usr/lib/vmware/weasel/utils
- There are a few files but the upgrade_precheck.py is of interest to us
- Delete upgrade_precheck.pyc (compiled version)
- Move upgrade_precheck.py to upgrade_precheck.py.old (because the file can not be edited due to some immortal flags and lack of tools to remove these flags)
- Cp upgrade_precheck.py.old > upgrade_precheck.py
- Edit upgrade_precheck.py and search for line that MEM_MIN_SIZE you will find (4 * 1024). Edit the number 4 to make it suitable for you. i made i to 1
- List all processes (ps -c | grep install) and kill the installer by pid
- now in that console run the installer with /bin/install
- Continue as normal
and the install has completed.
