Finally I found the problem but I still don't understand it.
The problem appears to be that I install using the Supermicro IPMI with
Installation goes well but after that I am unable to login remotely and
get the error "systemd-readahead-collect: Failed to open pack file:
Read-only file system". The system appears to hang.
When I hook up a screen and keyboard I can login normally and everything
works fine, this is very strange and annoying as I now need to install
every node in the datacenter.
I also tried logging in after startup but when I check the IPMI, I only
get a black screen.
Now I started using cobbler for using PXE boot with latest nightly
release, but I still have to install and configure the node. How can I
push the installation automatically so I can install unattended?

I tried both methods. When I use " storage_vol=:4000:::: " and "
mem_overcommit=0" everything installs fine.
But after I reboot the node i get the screen "login as admin to
configure" and the system hangs.
After several seconds I get the message
"systemd-readahead-collect: Failed to open pack file: Read-only
When I only use " mem_overcommit=0 ", I cannot install the node as the
Disk Space Check tells me I need a bigger drive.
"Available Space: 14305MB"
"Required Space: 26782MB"
This should be less:
0*32 + 8(32<64) = 8GB Swap.
Plus the storage ovirt needs itself (300MB?)
I tried ovirt-node 2.5.1 and 2.5.2
