Description of problem:
If I give the VM "only" 1 GB of memory then it hangs doing the
dependency calculation. Upping memory to 2 GB fixes the issue.
Version-Release number of selected component (if applicable):
RHEL 6 beta 2
Steps to Reproduce:
1. Install RHEL 6 beta 2 in a 1 GB VM from DVD ISO.
2. Select "Desktop".
Hangs (or takes many hours) doing dependency calculation.
Should be able to install in what is really quite a lot of memory.

Here it hangs on "Writing storage configuration to disk"
I configured 2GB RAM. With 1GB RAM BZ #610261 applies.
When switching to a console cat /proc/loadavg shows about 1.07. Meminfo shows about 1.6Gbyte free memory.
The lvm command shot off by anaconda went to be a zombie.
There three related bugs filed: This one, #610261 and #610510.
All of them have in common that the installation failed with this or similar behaviour when installed as a KVM guest. It seems that this bugs are not related to anaconda but with virtio or other KVM related drivers.
Using ESX 4.0 as a virtualization platform, the installation goes trough smoothly, even with only 512Mbyte of RAM.
I'll try to figure out what the problem can be...
I had a similar failure installing RHEL6 beta2 under citrix xen with 512MB memory. It got as far as "Transfering image to disk" then froze there. It did work when I increased the memory to 2GB. The first RHEL6 public beta didn't show this problem.
Is anyone seeing an "Installer exited abnormally" message on tty1? Can you even switch VTs when the machine hangs?
Yes, very strange. I just tried this process again, and this
time the error is as Chris describes:
install exited abnormally [1/1]
The system will be rebooted when you press Ctrl-C or Ctrl-Alt-Delete.
This however is *not* what I saw when I first reported this bug.
Now I tried it a third time, and the install proceeds perfectly normally.
So I gather the original bug report is very intermittent. I will try it over
again a few times.
I tried it another 3 times, and it worked fine each time.
I did notice that the kernel we shipped in RHEL 6 beta 2 does
tend to cause random segfaults in user applications when
run on top of KVM. There was a suspicion that this is caused
by KSM. There's a great deal of randomness in what I'm
seeing in this bug, so it could well be down to the same thing.

Ah, yes, that would make this a dup of bug 607650

Correct, sometimes up to 10 kvm installs are needed to get one to fail.
