I can confirm this bug. Unaware of this bug report, I came to the same conclusion today. Googling "noop xen bug debian" led me to this bug report.
Before pvops kernel, -xen kernel set noop for domUs by default, while pvops kernel sets cfq for domUs. Severity of this bug is higher than "wishlist", as observed I/O penalty in my case was critically high. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
