Hi,

how can I see who's who?:
# xm block-list vm1
Vdev  BE handle state evt-ch ring-ref BE-path
768    0    0     4      11     1036  /local/domain/0/backend/vbd/9/768
832    0    0     3      12     1037  /local/domain/0/backend/vbd/9/832
# xm block-list vm3
Vdev  BE handle state evt-ch ring-ref BE-path
768    0    0     4      11     1036  /local/domain/0/backend/vbd/10/768
832    0    0     3      12     1037  /local/domain/0/backend/vbd/10/832

If I want to detach the CD-ROM drive to enable media change, what's the correct 
device?

Did someone forget a translation for "768"? 768 is 0x300, and /dev/hda has 
major 
3, minor 0. Considering that "xm" is a python program, shouldn't it translate 
the 
numbers to something more useful? Likewise why not allow device names for 
"block-
detach" as well?

Regards,
Ulrich
