Hi everyone, I was trying to build a new machine but the system keeps rebooting. I used the lasted unstable version from xen-unstable.hg. I have tried with Fedora 16 (kernel 3.3.0-8) and Xubuntu 11.10 (3.0.0.17-generic). The output to my serial console is attached. Cheers, Francisco _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org

1: correct LDT checks 2: add address validity check to guest_map_l1e() 3: use {rd,wr}{fs,gs}base when available 4: check for canonical address before doing page walks Signed-off-by: Jan Beulich <jbeulich@suse.com>

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.

Hi Andi, This series of patches implements the Xen paravirt-ops interface. It applies to 2.6.21-rc7 + your patches + the last batch of pv_ops patches I posted. This patch generally restricts itself to Xen-specific parts of the tree, though it does make a few small changes elsewhere. These patches include: - some helper routines for allocating address space and walking pagetables - Xen

Hi, This is the Xen implementation for the paravirt_ops interface. The series is based on 2.6.22-rc1-mm1, and I think its ready to be cooked in -mm with a view to being merged in 2.6.23. The first part of the series is some small changes to the core kernel. Apart from the new code added in "Allocate and free vmalloc areas" (posted many times before), they are simply a few one-liners
