ionice is definitely a xen topic / issue.
widespread adaption is still missing and very much desirable.

The only good documentation I know was provided by Oracle somewhere
along the Oracle VM docs.

While I see that people that constantly ask instead of searching need
to be moderated, you also have to value based on the topics
interestedness.

It IS tricky to correctly specify ionice settings from the domU config
file, and until we all can do it like correctly writing a normal [disk
= "" ] stanza, I'd suggest you consider the topic very interesting.

And really, as it seems you didn't figure it relates to xen you might
wanna hold back a little!

Trust your guts, and even more trust if people tell you.
Others will always notice before one self does.
