Calculating real cpu usage of Xen domains correctly!
Hi all,
With the new vm-tools we are trying to get top like capabilities going
correctly. Currently we have a program vm-list that has some of this
capability but is dependent on the cpu time given by libxc calls
(xc_get_dom_info & xc_domain_get_cpu_usage). These two functions give
you how much time (in nanoseconds, why is this not documented) the
domain has been actively used. Approaches:

xen: introduce vcpu_block
Rename do_block to vcpu_block.
Move the call to local_event_delivery_enable out of vcpu_block, to a new
static function called vcpu_block_enable_events.
Use vcpu_block_enable_events instead of do_block throughout in
schedule.c

scheduler independent forced vcpu selection
I''m working on a new hypercall, do_confer, which allows the directed
yielding of a vcpu to another vcpu. It is mainly used when a vcpu fails
to acquire a spinlock, yielding to the lock holder instead of spinning. I
ported the ppc64 spinlock implementation for the i386 linux portion. In
implementing the hypercall, I''ve been trying to figure out how to get
the scheduler

[Patch] Fix IDLE issue with sedf scheduler on IA64
Hi, Dan,
This patch fixes strange behavior on IA64, that IDLE is
scheduled more than Dom0 with default sEDF scheduler.
The key point is reprogram_ac_timer at the end of ac_timer
dispatcher, which programs local apic timer with expire of next ac_timer
on x86. Higher precision lapic timer can trigger ac_timer more precisely
than simply done in PIT interrupt handler. That works perfectly on x86

Please help: domU becomes unresponsive
Hi all, sorry to intrude on xen-devel, but I think I need direction
from the expertise here. I''ve admin''d Xen servers of various flavors
for a couple years, but never seen this before. After a period ranging
from several hours to several days, my primary database and
development DomU completely locks up. Net disconnects, but CPU(sec)
continues to tick in xentop. No errors, and

[PATCH] Accurate vcpu weighting for credit scheduler
Hi,
This patch intends to accurate vcpu weighting
for CPU intensive job.
The reason of this problem is that
vcpu round-robin queue blocks large weight vcpus
by small weight vcpus.
For example, we assume following case on 2pcpu environment.
(with 4domains (each domain has 2vcpus))
dom1 vcpu0,1 w128 credit 4
dom2 vcpu0,1 w128 credit 4
dom3 vcpu0,1 w256 credit 8
dom4 vcpu0,1 w512 credit 15

vpmu=1 and running 'perf top' within a PVHVM guest eventually hangs dom0 and hypervisor has stuck vCPUS. Romley-EP (model=45, stepping=2)
This issue I am encountering seems to only happen on multi-socket
machines.
It also does not help that the only multi-socket box I have is
an Romley-EP (so two socket SandyBridge CPUs). The other
SandyBridge boxes I''ve (one socket) are not showing this. Granted
they are also a different model (42).
The problem is that when I run ''perf top'' within an SMP PVHVM
guest,
