On tickets.oebb.at : add Eurail as a discount and select one-way tickets (no booking fee). You’ll surely have to split the booking :

• Roma Termini - Venezia Mestre 13€ seat reservation
• Venezia Mestre - Wien Hbf 10€ Tarvisio supplement + 3€ optional (but recommended) seat reservation

There is a night train which might interest you as it is a long journey. Due to engineering works it doesn’t run this summer via Rome so you’ll have to board it at Bologna. Check couchettes or sleepers prices on tickets.oebb.at too

Let us know if something doesn’t work, mentioning your travel date.

Nightjets often do not run at weekend from/to Rome due to works on the line. Same this summer for all days. More information on nightjet.com

I have one question. Why won't it let me reserve a seat on some trains in Italy? If I do that I am going to buy a ticket there are places but if I only want to reserve a seat "no ticket avaliable" and this train from Rome to Bolzone is empty

You need do to 2 bookings, ÖBB can't handle multiple trains : first Rome - Bologna and then Bologna - Bolzano for example.

REX regional trains : seat reservations not possible
