Hello, i read something about buffered IO in some hypervisors. So most hypervisors bufferes all disk operations and after a while take the cpu to execute all operations as one block. Is this the standard behavior of xen hypervisor? I didn''t found any information about that. Is there any possiblity to de-/activate it?

If you use file:/ (which is not recommended), then you''d get buffered I/O. For everything else (including phy:/ and tap:/), you should get unbuffered I/O. -- Fajar
