Thanks, that was the problem and the solution.
Found the post, it's easier to find something when you know what you are
looking for.

Hi,
has anybody installed ovirt-node on a bootable usb stick? If the
hypervisor
is less than 1GB in size, why does installation require 70GB of
disk space?
It would be perfect to run nodes from usb without any disks.
Thanks

Sorry for not asnwering to the list, here are my previous post:
"How much memory do you have? It seems that it's calculating how much
swap it will need and turns that needs at least 70 GB disk space."
There is a thread in this forum that has the calculations that ovirt
does for it. You can change this values on the boot options.

Those values are also shown on the installer screen right before
entering the password and can be changed
As sometimes searching the list can be a pain, I'll just repost it:
You can do this with 2 different methods, both of which are on the
kernel command line during boot. Simply hit TAB when you're selecting
the install option and add one of the options below to the command line.
1. You can set " storage_vol=:XXX:::: " where XXX is the desired
size of the SWAP partition in MB. It has a minimum size of 5MB.
This lets you set a static size for swap.
2. You can set mem_overcommit=0. This will change our calculation
to not add any swap for overcommit. It will still calculate a value
based on the amount of RAM, but not as large as with the overcommit.
The swap size is calculated at mem_overcommit*RAM + <BASE_SWAP>
BASE_SWAP is calculated using this formula:
if MEM_SIZE < 4GB:
BASE_SWAP = 2GB
elif MEM_SIZE < 16GB:
BASE_SWAP = 4GB
elif MEM_SIZE < 64GB:
BASE_SWAP = 8GB
else:
BASE_SWAP = 16GB
We are planning to expose these option in the TUI installer, just not
there yet.
