search for: update_va_map

Greetings, I have a technical question about update_va_mapping_otherdomain....... I have two components: a C program linked against libxc and a kernel module which performs the following simple sequence of events from domain zero: 1. Pause guest (unprivileged) 2. Grabs the PTE associated with a random (but present) page within the guest''s ker...

At the bottom of page 40 of the Interface manual, an "update_va_mapping" prototype is shown, but it should be an "update_va_mapping_otherdomain" prototype. (This prototype introduces the "update_va_mapping_otherdomain" hypercall documentation, so the association between hypercall and documentation is wrong.) Patch below. - bruce diff...

I''m to porting a lightweight kernel to Xen 3.0.4-x86_64 and have run into a problem while setting the PML4. Xen complains that it has a bad type of ''PGT_writable_page'' (e8000001), while it expects 80000000. However, I''m almost certain that this is not the case. I added a routine to do a depth first search of the four page table levels looking for this machine

Changes from v3: - mini-os configuration files moved into stubdom/ - mini-os extra console support now a config option - Fewer #ifdefs - grant table setup uses hypercall bounce - Xenstore stub domain syslog support re-enabled Changes from v2: - configuration support added to mini-os build system - add mini-os support for conditionally compiling frontends, xenbus -

This patch series contains a set of patches making minios rather easier to use, from an application development point of view. Overview of patches: 1 Command line argument parsing support, from Xen. 2 Weak console handler function. 3 Build system tweaks for application directories. 4 Trailing whitespace cleanup. (because it is very messy) Patch 4 is likely to be more controversial than

This patch series implements the Linux Xen guest in terms of the paravirt-ops interface. The features in implemented this patch series are: * domU only * UP only (most code is SMP-safe, but there's no way to create a new vcpu) * writable pagetables, with late pinning/early unpinning (no shadow pagetable support) * supports both PAE and non-PAE modes * xen console * virtual block

Unlike full virtualization in which the virtual machine provides the same platform interface as running natively on the hardware, paravirtualization requires modification to the guest operating system to work with the platform interface provided by the hypervisor. Xen was designed with performance in mind. Calls to the hypervisor are minimized, batched if necessary, and non-critical codepaths
