Hi,
I saw the following error message when I shut down a domain. The error
message showed that release of device(vbd/51712) failed. But the device
was tap, was not vbd. I think that a cause of the error message is
because _releaseDevices() calls destroyDevice() by wrong device class.
[2008-11-26 10:29:21 5554] DEBUG (XendDomainInfo:946)
XendDomainInfo.destroyDevice: deviceClass = vbd, device = vbd/51712
[2008-11-26 10:29:21 5554] ERROR (XendDomainInfo:1999) Device release failed:

Traceback (most recent call last):

rc = self.getDeviceController(deviceClass).destroyDevice(devid, force)

DevController.destroyDevice(self, devid, force)

in destroyDevice
self.writeBackend(dev, ''online'', "0")
File "//usr/lib/python/xen/xend/server/DevController.py", line 474,
in writeBackend
raise VmError("Device %s not connected" % devid)
VmError: Device 51712 not connected
This patch fixes above problem. By the patch, destroyDevice() is called
by correct device class.
