Respected Sir,
Thank you for paying attention to my mail.
I am an undergraduate student of computer science.I want to do some good
project in xen.I read the paper "affinity-aware dynamic pinning scheduling
for Virtual machine" (copy is attached).Reading this paper i thought of an
following idea..
"In xen,Qemu emulates the hardware to guest O.S.so
<http://o.s.so/>guest kernel is unaware of underlying real hardware.So
scheduling of
processes which guest kernel will do,may not be optimized. In credit
scheduler it schedule the VCPUs according to their weights but process
scheduling on VCPU may not be optimized.
My basic idea is scheduling these processes according to real hardware and
the scheduling domains accordingly."
Sir,is this idea already implemented in xen?
Also,I want to know resource allocation policy used by xen.
Sir,can you suggest any improvement to above idea or any good project idea
in resource allocation or scheduler or in memory management of xen?
Thanking you

It''s aware of the cpu model given to it, which is the most important thing for scheduling. Do you perhaps mean that the guest kernel is unaware of the actual cpu and cache topology? -George _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
