SATA pass-through woes
I''m trying to pass my SATA controller through to a domain and have run
into a weird situation. I have two machines with the same general
class of hardware (Intel PIIX) and the pass-through works on one
machine but not the other. On the non-working system, the SATA
controller makes port reads, but they don''t return the correct values.

[PATCH 0 of 2] Paging support updates for XCP dom0
...to harvest those return values and retry.
The second patch adds retry loops to all backend grant operations (map and

[PATCH] xenstore-stat v2
The entries in xenstore have permission attributes. The
attributes can be easily altered by xenstore-chmod, however,
I cannot find a easy way to see them.
I''ve modified xenstore_client.c to raise a new utility.
The utility checks the permission and makes an easy-look output.
Please tell me any suggestions.
Thanks.
