Hi, I am trying to release domU pages from page_list and xenpage_list after domU shutdown while retaining the rest of the domain information. To achieve this in __domain_finalise_shutdown i call domain_relinquish_resources. This is failing to release pages from page_list for type PGT_l2_page_tables and crashing dom0. To be specific, while testing on mini-os i saw that when domain_relinquish_resources calls relinquish_memory for PGT_l2_page_tables, this eventually calls free_l2_table which fails at map_domain_page()...

Two things: 1. I''m not convinced ''xm crash'' is needed - ''xm destroy'' will do this (and if you want a dump, do ''xm dump'' followed by ''xm destroy'') 2. I don''t see the point of the --noreboot option on ''xm dump'' -- I think this command should simply live-dump the specified domain - as

Hi all, this small patch series implement guest SMP support for ARM, using the ARM PSCI interface for secondary cpu bringup. Stefano Stabellini (4): xen/arm: basic PSCI support, implement cpu_on xen/arm: support for guest SGI xen/arm: support vcpu_op hypercalls xen: move VCPUOP_register_vcpu_info to common code xen/arch/arm/domain.c | 66 ++++++++++++++++++++++++

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.

Hello everyone, this is the fourth version of the patch series that introduces ARMv7 with virtualization extensions support in Xen. The series allows Xen and Dom0 to boot on a Cortex-A15 based Versatile Express simulator. See the following announce email for more informations about what we are trying to achieve, as well as the original git history: See
