Thread-topic: [Xen-devel] [RFC] Add static priority into credit scheduler
> I'd be interested to hear others' opinions.

Just found Daniel is working on EmbeddedXen to support hard realtime OS(Xenomai 
on top of Xen), from thread http://markmail.org/message/o2vyzy7ngf7oluw4
Add Daniel in, hope he can give more opinions on it...
Hi Daniel, we are talking about adding static priority in xen's credit 
scheduler to support real time guest. You can see the thread from 
http://markmail.org/message/vn62u7qdbmswms5a, in case you missed it.
Could you give us your concerns/opinions about xen to support real time OS, 
such as the scheduler, interrupt latency, the overhead introduced by Xen,etc.? 
Thanks!

Best Regards,
Disheng, Su
