[Xen-API] XCP 1.0-beta: SM backend driver

[Tomoe Sugihara <sugihara@xxxxxxxxxxxxx>]

Hi,

I got the following error while testing XCP 1.0 beta with VastSky SM backend:

----------------------

This is because blktap2.VDI_PLUG_TYPE doesn't have the key 'disk'.
'disk' for vid_type used be usable in XCP 0.5, but seems like it isn't anymore.

Is there any suggested policies on the value?
I referred to the documentation(http://www.xen.org/files/XenCloud/storage.pdf),
but I couldn't find any.

Incidentally, SHMSR.py also has "disk" as vid_type and should causes an error.

Best,
Tomoe
