The problem is: There is no mechanism to detect block device setup failure
Network devices have the same problem, and are fixed with this too.
I handling this problem in the way suggested by aliguori:
- hotplug scripts write a "hotplug-status" node on store
- Xend DevController.createDevice() check verify this node and return success
or throw an exception on failure.
- If no changes in "hotplug-status" node after DEVICE_CREATE_TIMEOUT seconds
Xend throw an exception showing the problem with hotplug scripts.

hotplug ones. Added evalVariables and findCommand functions to that, which we
use to clarify the handling of variables being passed in as command line
variables.
Make vif-bridge able to find the bridge for itself if only one bridge is in
use. This means that it is not necessary to specify a bridge in many
configurations. Allow the bridge to be specified on the command line, meaning
that a default may be provided in the xend-config.sxp if desired.
Added xenstore_read_default to xen-hotplug-common.sh, which reads from the
store but uses a given default if the path in the store is not present. This
is used by vif-bridge to allow the store details (i.e. those given to xm create)
to override the default value given in the xend-config.sxp.
Remove vif-bridge setting -- the value can be specified on the vif-script
command line if necessary.
Added examples for network-nat/vif-nat.
Added lots of big comments.

code into vif-common.sh.
Fix the antispoofing in network-bridge to allow forwarding from physical
device to bridge, and vif0.0 to eth0.
Change the interface between netback driver and vif hotplugging scripts. The
mac address and bridge details are read from the store directly by the script,
so that the kernel driver does not need to get involved.
Remove an awful lot of cruft from vif-bridge. Move the iptables handling into
vif-common.sh, and fix it so that the new vif can get past the antispoofing
entries. Merge vif-nat and vif-route into this structure too.
Use ip instead of ifconfig to get necessary details.

- make xen-hotplug-common.sh (un)set locales.
- use xen-hotplug-common.sh in vif-bridge.
