Thanks for your Reply, but I don't understand what you mean with file:/,
phy:/ and tap:/. Can you explain please or give me some internet links?
Hmmm ... so you don't know what they are?

Then the simplest version is if you create the guests using some kind
of frontend (e.g. virt-manager), then you'll get unbuffered I/O.

To understand any answer deeper than that, you need to at least have
created a guest/domU from scratch, with manually-created domU config

OK, I found some useful information about this topic! Now I understand the differences about file, tap and phy. In the past I always used virt-manager to create guests. Virt-manager creates an image. So I think it is tap-mode as default, wright?

Thank you for your help!!!! It was really great! Now I know which keywords I have to use for my search and can study intensively this topic. ;-)
