Good day - This is my first post to this list , and I''m new to Xen - any help on this issue would be much appreciated . I downloaded, built and installed xen-4.2.1 (hypervisor and tools) on an x86_64 ArchLinux box updated to latest software as of today. I am trying to bring up a Linux guest from a remote iSCSI disk. The iSCSI-initiator (open-iscsi) logs in to the remote target OK and

Made the xenctrl.h and xenstore.h easier to use with C++: added ''extern "C"'' statements, moved the definition of enum xc_error_code above it''s typedef, and renamed a ''new'' parameter (''new'' is a C++ keyword).

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''ve been trying to have all spice features working on xen domUs since the end of 2011. Basic functions were already working. Adding qemu parameters manually for vdagent and usbredirection was and is also working (I made the patches to support them directly on xl). Qxl was never working: one bug on xen and one on qemu about qxl are fixed, the other xen bug found months ago on the

This patch implements the xenidc_channel interface using grant tables but leaves the channel bring-up and tear-down sequencing to a derived class (xenidc_gnttab_channel implements that). This code is part of the implementation of the xenidc_endpoint used for interdomain communication by the USB driver. Signed-off-by: Harry Butterworth <butterwo@uk.ibm.com>

Rather than just leaking pages that can''t be freed at the point where access permission for the backend domain gets revoked, put them on a list and run a timer to (infrequently) retry freeing them. (This can particularly happen when unloading a frontend driver when devices are still present, and the backend still has them in non-closed state or hasn''t finished closing them yet.)
