[Bug 1100843] Re: Live Migration Causes Performance Issues

[Chris Cormier]

I've been able to confirm the same as the OP regarding the different
Ubuntu distrubutions as guests. These tests should help ruleout/pinpoint
the kernel and modules.

Using the same 12.04 hypervisors for all tests.

Testing different guests I was able to determine.
-Lucid with default kernel is NOT affected.
-Precise with default kernel is affected.

The test...
I tared up each guest kernels and dropped them into the oposing distribution.

Results
-Lucid with Precise Kernel is NOT affected. 
-Precise with Lucid Kernel is affected.

Conclusion
12.04 Precise distribution guest is affected regardless of the kernel used.
