So to clarify, running something like 

 # dd if=/dev/zero of=/dev/null &

shows up in 'htop' with high I/O values but doesn't
show any I/O in 'chcontext --xid 1 -- htop'?

If so, please run both htop invocations with 
strace -fF on an unloaded host (minimal processes
and no guest running) and upload the dumps somewhere
where I can reach them.

If not, please clarify what issue you are observing
and provide some examples to test with.

Thanks in advance,
Herbert
