These are due to /var/run/xen-hotplug/block getting leaked

These are:
        libxl: error: libxl_device.c:894:device_backend_callback: unable
        to add device with path /local/domain/0/backend/vbd/9/5632
        libxl: error: libxl_create.c:935:domcreate_launch_dm: unable to add 
disk devices

/var/log/xen/xenhotplug.log contains:
        xenstore-read: couldn't read path backend/vbd/9/5632/node

For both of these I'm suspicious of:
11a63a1 libxl, hotplug/Linux: default to phy backend for raw format file

and to a lesser extent:
a508caf libxl: fix libxl__device_disk_from_xs_be to parse backend domid

It doesn't look like the bisector is looking at this, or else I'm
reading osstest's resource plan wrongly
