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?
No

I didn't found any information about that. Is there any
possiblity to de-/activate it?
I don't think so.

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.


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?


Thanks,
