This adds a backend_domname field in libxl devices that contain a backend_domid field, allowing either a domid or a domain name to be specified in the configuration structures. The domain name is resolved into a domain ID in the _setdefault function when adding the device. This change allows the backend of the block devices to be specified (which previously required passing t...

The series introduces auto-generation of the type definitions used in the libxl interface followed by auto-generation of a destructor function for each type. In the future it may be possible to use the related data structures for other purposes, for example auto-generation of the functions to marshal between C and language binding data types. tools/_libxl_types.h should be identical both before

This is v3 of my disk series. What were previously patches 01-06 have been applied. These are the tested and updated remainder, addressing the previous comments. 1 Preparatory work. 2-4 The new parser and its documentation. 5-6 Replace old parsers with calls to the new one. 7-8 Two features, one of them essential. 9 Basic test suite for disk string parsing, as adhoc script.

Grant references for the xenstore and xenconsole shared pages exist, but currently only xenstore uses these references. Change the xenconsole daemon to prefer using the grant reference over map_foreign_range when mapping the shared console ring. This allows xenconsoled to be run in a domain other than dom0 if set up correctly - for libxl, the xenstore path /tool/xenconsoled/domid specifies the

I think I posted this patch before, but it looks like it was in December 2012 (!). 1/1 libxl: introduce an option for disabling the non-O_DIRECT workaround Ideally it would go into 4.4, at least. Provided the corresponding qemu part has gone into qemu-xen, which I think it has. Can anyone confirm ?

Hey, I thought there was supposed to be an ability for domU''s to be put into a hibernated state (E.g. current running tasks and memory) when dom0 is shutdown or rebooted. When I look in my /etc/default/xendomains file, I have the variable''s "XENDOMAINS_SAVE=/var/lib/xen/save" and "XENDOMAINS_RESTORE=true". However, when I reboot, I always have to restart my

This patch series adds support for network buffering in the Remus codebase in libxl. Changes in V3: [1/5] Fix redundant checks in configure scripts (based on Ian Campbell''s suggestions) [2/5] Introduce locking in the script, during IFB setup.
