Does it really? I couldn't find this in the SVM spec.

Avi,
This is the patch to enable PLE, which depends on the a small change of
Linux scheduler
(see http://lkml.org/lkml/2009/5/20/447).
According to our discussion last time, one missing part is that if PLE
exit, pick up an unscheduled vcpu at random and schedule it. But

Hi,
I would like to call attention to the SQLite performance under KVM in
the current Ubuntu Alpha.
http://www.phoronix.com/scan.php?page=articleitem=linux_2631_kvmnum=3
SQLite's benchmark as part of the Phoronix Test Suite is typically IO
limited and is affected by both disk and filesystem

The dirty bitmap copied out to userspace is stored in a long array, and gets
copied out to userspace accordingly. This patch accounts for that correctly.
Currently I'm seeing kvm crashing due to writing beyond the end of the alloc'd
dirty bitmap memory, because the buffer has the wrong size.

Both VMX and SVM require per-cpu memory allocation, which is done at module
init time, for only online cpus. When bringing a new CPU online, we must
also allocate this structure. The method chosen to implement this is to
make the CPU online notifier available via a call to the arch code. This
In the process of bringing down CPUs, the SVM / VMX structures associated
with those CPUs are not freed. This may cause leaks when unloading and
reloading the KVM module, as only the structures associated with online
CPUs are cleaned up.

They are globals, not clearly protected by any ordering or locking, and
vulnerable to various startup races.
Instead, for variable TSC machines, register the cpufreq notifier and get
the TSC frequency directly from the cpufreq machinery. Not only is it
always right, it is also perfectly
