If you give the VM only 512 MB of RAM, the text-mode installer kicks in. It does not prompt you to configure anything related to the network or hostname. The system boots up without a network interface configured. Also, it won't let you choose the install mode, I guess it defaults to Minimal (which is fine by me, but still it's a bug).
If you give the VM 768 MB of RAM, the GUI installer is launched, and this one allows you to configure the hostname, the networking details, and choose the install mode. The system boots up with networking and all the niceties enabled.

I saw this in rhel 6 and newer fedora versions, the anaconda text installer comes with minimal options, to have full options you should use GUI or use kickstart.

It's possible--according to RH, it's streamlined and simplified--accordingto everyone else, it's become a crippled thing. I know that there is no option for disk partitioning, and possibly no option for custom package selection.

I don't know if this relates or not, but attempting to install FC15 in a VM with only 512M of memory, fails: the kernel / installer hangs. It looks like the minimum memory requirements to install FC15 (and it looks like RHel / CentOS 6 as well) is something greater than 512meg and probably something closer to 1G.

http://wiki.centos.org/Manuals/ReleaseNotes/CentOS6.0 4. Known Issues The installer needs at least 392MB of memory to work. Text mode will automatically be used if the system has less than 652MB of memory.

Yeah, that's it, I'm reading the notes now.
It's not terribly bad, since there are few systems nowadays with only 512 MB of RAM (that you would want to run C6 on). Just a bit annoying.

It would be nice if there were a straightforward way to adjust the configured devices on an installed system like you have to do if you want to restore a backup onto different hardware. It's not impossible, but you have to know as much about hardware and drivers as the mostly-undocumented installer to do it. If it were simple, you could install an image in a comfortably-equipped VM, then clone it to a minimal runtime system. I suppose you could go though those motions to get the kickstart file that is logged as part of the install and use that to repeat the install.

Someone posted that you can use VNC to install CentOS 6.
Excerpts:
"Anaconda therefore includes a Virtual Network Computing (VNC) mode that allows the graphical mode of the installer to run locally, but display on a system connected to the network. Installing in VNC mode provides you with the full range of installation options, even in situations where the system lacks a display or input devices."

It means you get to do a graphical install, which you otherwise can't if you don't have enough RAM i.e. less than 652MB.
hth Andy
Surely Russ would have known that, if he followed the link to the RHEL6 documentation on THIS VERY MATTER.
Russ, there's no need to be rude to someone who's trying to help.

Russ point's out that if installer lacks enough RAM for full graphical install it will not have it for VNC install either.
That very much might be true, but you have nothing to loose to try and report back

Can you decieve this installer with swap?

Overcommit on the host, if you can do that.
If you could get a shell before anaconda starts you might possibly be able to set up swap; have never tried that.
