There is a race case where the user does ''poweroff'' and at the same time the system admin does ''xl shutdown''. Depending on the race, the system_state will be SYSTEM_RUNNING or SYSTEM_POWER_OFF. If SYSTEM_RUNNING we just end up making a duplicate call to ''poweroff'' (while it is running). That will fail or execute (And if executed then it will

Hello, This patch allows userspace tools on a domU to setup a watch on the xenstore. It does this by intercepting XS_WATCH requests written to /proc/xen/xenbus and then re-submitting the request to the in-kernel xenstore interface, in linux-2.6-xen-sparse/drivers/xen/xenbus/xenbus_xs.c. When a callback occurs, an in-kernel function is invoked, which then reconstructs a response in the format

The xenbus bus type uses device_create_file to assign all used device attributes. However it does not remove them when the device goes away. This patch uses the dev_attrs field of the bus type to specify default attributes for all devices.

drivers/xen/xenbus/xenbus_comms.c uses full memory barriers to communicate with the other side. For guests compiled with CONFIG_SMP, smp_wmb and smp_mb would be sufficient, so mb() and wmb() here are only needed if a non-SMP guest runs on an SMP host. Switch to virt_xxx barriers which serve this exact purpose. Signed-off-by: Michael S. Tsirkin <mst at redhat.com> ---

Hello I have a lot of problem using the xenbus api (in xen-3.0-testing). I had to modify the network backend driver (file netback.c), and each call to a xenbus function in a virtual machine make my machine reboot (not the virtual, the real machine). for example, I ''ve add this line of code (wich is useless):

Hi, This patch series fixes the S3 resume of a domain running xenstored and a frontend over xenbus (xen-netfront in my use case). As device resume is happening before process resume, the xenbus frontend resume is hanging if xenstored is not running, thus causing a deadlock. This patch series is fixing that issue by deferring the xenbus frontend resume when we are running xenstored in that same
