xm block-attach and block-detach

 looking for some disucssion on block-attach and block-detach questions.

I am trying to dynamically add an additional file based device to a guest.

e.g "xm block-attach 196 /OVS/running_pool/vguest1/data1.img /dev/sda w"

if i block-attach using a frontend dev of /dev/sda, the guest OS does not see the device even after scanning scsi bus.

if I attempt to change the frontend /dev/xvda it claims my device is already defined

block-detach does not seem to fully cleanup. 

executing block-detach on the device says it is not connected but it still shows in the xm block-list <domid>

Howdy, Stranger!
