Description of problem:
Anaconda needs to have at least 1GB RAM for GUI installation, however RHEL6 can run on 512MB without any problems.
Try to install RHEL6 beta 2 with less than 1GB RAM.
Steps to Reproduce:
1. Install memory (under 1GB RAM)
2. Boot RHEL6 b2 installation DVD
3. Select graphical installation
Anaconda shows a warning that there has to be at least 1GB RAM for GUI installation and continues with text installation.
Be able to run GUI installation with less than 1GB RAM (512MB is acceptable).
This issue has been proposed when we are only considering blocker
issues in the current Red Hat Enterprise Linux release.
** If you would still like this issue considered for the current
release, ask your support representative to file as a blocker on
your behalf. Otherwise ask that it be considered for the next
Red Hat Enterprise Linux release. **
Ok, I've marked it for 6.1 instead. Is it OK or shall I create a support case?
This is not a bug:

memory: increase the RAM limits, check for URL installs (#549653).
Due to higher memory consumption of LVM, kernel, anaconda and other
running processes in general our current memory limits are insufficient
and the increase is neccessary. I am also introducing additional check for
URL installs which require another 108 MB from the ramdisk, no need to
penalize other install methods.
This is the current memory budget:
- unpacked initrd takes 63 MB
- running processes (anaconda, loader, udev, nm): 67 MB (estimate)
- peak LVM memory consumption: up to additional 56 MB
- with URL install install.img takes additional: 108 MB
- memory requriements of X additional: 256 MB (estimate)
Currently we always expect there will be calls to lvm (though we could do
another memory check just at the moment where the necessity arises). All
of the estimates are on the upper bound, still I am running into OOM
easily with text install+http stage2+lvm detection with the old limits.
