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?NoI 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?
