CentOS - Jun 2016 - Minimum RAM requirement for CentOS 6.x graphic installer?

Hi,

The title says it all. What's the minimum RAM requirement for the CentOS
6.x graphic installer? In our public libraries we have some old hardware
running CentOS 5, and I wonder if some of these machines can be upgraded
to CentOS 6. Unfortunately RHEL 5.x' nifty text mode installer got
seriously crippled with version 6.x.

Cheers,

Niki Kovacs

I believe the limits are bound by the installer:

https://github.com/rhinstaller/anaconda/blob/rhel6-branch/isys/isys.h#L23

Its possible to install the OS and then reduce the RAM if you want it
to be less.  Something I've done for VMs in the past.

From the CentOS 6.8 Release Notes:

The installer needs at least 406MB of memory to work. Text mode will
automatically be used if the system has less than 632MB of memory.

So, I would say for the GUI installer (using 256MB increments), 768MB is
the lowest round number value of usable RAM.
