[Bug 1100843] Re: Live Migration Causes Performance Issues

[Chris J Arges]

I found that two patches need to be backported to solve this issue:

ad0b5321f1f797274603ebbe20108b0750baee94
211ea74022f51164a7729030b28eec90b6c99a08

I've added the necessary bits into precise and tried a few tests:
1) Measure performance before and after savevm/loadvm.
2) Measure performance before and after a migrate to the same host.

In both cases the performance measured by something like lmbench was the same as the previous run.
A test build is available here:
