Hi, There is the new hotplugging feature in Sunstone in ONE 3.6.
I tried to attach an ISO image with type CD-ROM. In this case, i had a following error: Sat Aug 25 21:52:18 2012 [VMM][I]: Successfully execute transfer manager driver operation: tm_attach. Sat Aug 25 21:52:19 2012 [VMM][I]: Command execution fail: /var/tmp/one/vmm/kvm/attach_disk one-144 /var/lib/one//datastores/0/144/disk.2 vdb 1 PFZNTV9EUklWRVJfQ.....

I also notice that ONE Doesn't recognize attached Context ISO. For example, if I define virtio bus in a Context section context ISO will be attached as 'vdb'. Then if I try to attach a device with 'vd' prefix it would be forced as 'vdb' again (with an error in log). Maybe would be a good idea for new releases to consider adding context disk in the device list (with possibility to detach it).
