Concerns with Xen PVH / HVMLite boot on Linux x86

I've been helping a bit with streamlining proper upstream support for Xen on x86 Linux. One of the items I have decided to take on is the so called "dead code" concern in theory present on x86 Linux Xen guests largely in part due to the radical way in which old PV Xen x86 Linux guests boot.

The XenServer team has made a number of significant performance and scalability improvements in the XenServer 7.0 release. This is the fourth in a series of articles that will describe the principal improvements. For the previous ones, see: http://xenserver.org/blog/entry/dundee-tapdisk3-polling.html http://xenserver.org/blog/entry/dundee-networking-multi-queue.html http://xenserver.org/blog/entry/dundee-parallel-vbd-operations.html In this article we return to the theme of I/O throughput. Specifically, we focus on improvements to the total throughput achieved by a number of VMs performing I/O concurrently. Measurements show that XenServer 7.0 enjoys aggregate network throughput over three times faster than XenServer 6.5, and also has an improvement to aggregate storage throughput. What limits aggregate I/O throughput? When a number of VMs are...
