Xenapi: Fix tempest for xenserver device tagging
This patch is for tempest modification to fit xenserver device
tagging implementation about block-device tagging.
There are two reasons that multiple paths will exist for a tagged
disk:
1) HVM guests may not have the PV drivers installed, in which
case the disk will be accessible on the IDE bus. When the PV
drivers are installed the disk will be accessible on the Xen bus.
2) Windows guests with PV drivers installed expose devices in a
different way to Linux guests with PV drivers. Linux systems will
see disk paths under /sys/devices/, but Windows guests will see
them in the registry (e.g.
HKLM\System\ControlSet001\Enum\SCSIDisk). These two disks are both
on the "xen" bus.
