* xenbus: rebind irq on restoreJeremy Fitzhardinge2008-05-271-11/+12
| | | | | | | | | | When restoring, rebind the existing xenbus irq to the new xenbus event channel. (It turns out in practice that this is always the same, and is never updated on restore. That's a bug, but Xeno-linux has been like this for a long time, so it can't really be fixed.)

* xen: add the Xenbus sysfs and virtual device hotplug driverJeremy Fitzhardinge2007-07-181-0/+233
This communicates with the machine control software via a registry residing in a controlling virtual machine. This allows dynamic creation, destruction and modification of virtual device configurations (network devices, block devices and CPUS, to name some examples).
