Hi all, this is the long awaited patch series to add xen device model support in qemu; the main author is Anthony Perard. Developing this series we tried to come up with the cleanest possible solution from the qemu point of view, limiting the amount of changes to common code as much as possible. The end result still requires a couple of hooks in piix_pci but overall the impact should be very

I ran a bisect to find out when Windows XP 32 bit becomes unusably slow. And I found the changeset that caused it. ========== The problem: ========== Windows 8 64 bit and 32 bit run fast and fine in the newest xen versions. Windows XP 32 bit runs unusably slow in anything new that I built from xen-unstable, but runs fast in 4.1.2 and 4.1.3 stable. While it is running slow, "xm top" or

This patch series is a reworking of a series developed by Mukesh Rathor at Oracle. The entirety of the design and development was done by him; I have only reworked, reorganized, and simplified things in a way that I think makes more sense. The vast majority of the credit for this effort therefore goes to him. This version is labelled v13 because it is based on his most recent series, v11.
