While you can resize the underlying disk, but extending the root
filesystem can be a bit tricky (It can be done locally with
virt-resize, but AFAIK oVirt does not provide a UI or an API to run it
after the image had been uploaded).

We typically just add an extra disk and mount it where we need extra space.
