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.
