to respond first time. For restored and unpaused domains there is no need for
the console to output data, so we cannot use this as a way to detect the
liveness of a console. Instead, a command must always be sent to the console,
which means that this failure can only be detected once the constructor of the
Console class has returned successfully. The __chewall loop still remains, in

console before executing commands, but we no longer treat failure of that

This also restores the broken teardown functionality for file: devices -- the
writing of XENBUS_PATH/node had been removed, but this is required for file
device teardown.

Fix the unpause_basic test. The console will appear to have failed, given the
current Console.py API, because no bytes have come from it, but that's not a
failure -- an unpaused domain has no reason to output any more data. We need
to send a command to the domain before we can be sure whether it is alive or
dead, so move the FAIL call, allowing the console connection to throw
ConsoleError.

Fix the 06_block-list_checkremove test. The use of string.find was invalid

domain time to close down the device) so we need a time.sleep(1) call before

Check when using physical devices that the device is not already in use. Using
a device from two guests, or from dom 0 and a guest, can destroy the filesystem,
and this check prevents that. This should ensure that the xm tests
11_block_attach_shared_dom0 and 12_block_attach_shared_domU should pass.
Closes bug #331.
Devices may be shared only if all uses are read-only. If anyone has read-write
access to a device, then no sharing is allowed.
The mode in the config file may now have an exclamation mark appended, to
indicate that devices may be shared (i.e. that this new check should be
bypassed). This supports some network block devices, but is clearly dangerous
and should only be used when you know what you are doing.
The mode specified in the config file is now written explicitly to the store,
To implement this, the blkback driver has been changed to create two entries
in /sys describing each device in use. This means that we can determine which
devices are in use without crawling through the store.
The physical-device node has been changed to give the major and minor of the
device, separated by a colon. This means that we do not need to pack these
numbers into one, removing the restriction to 8 bit minors that we had in place
before.
The mode specified in the config file is now written explicitly to the store,
rather than using the presence or absence of a read-only node. This supports
the write-sharing override above.
If the device is in use, a new hotplug status of "busy" is written to the
store, and a message is written to a new hotplug-error node. Xend uses these
things for diagnosis.
The block scripts do not need to handle online or offline events, so this
support has been removed. These scripts can be called twice, depending upon
the hotplug config, so they now identify the second run and do not attempt to
set up the device again.
The device directories in the store are cleaned out before new details are
written there. This prevents stale information from messing up block device
hotplugging. This will be one cause of "blkback: changing physical device
not supported" messages.
