Hi,
How does this work if we start off a guest with 3 disks attached to the usb-bot SCSI controller. Then hot-unplug the 2nd disk.
You can't hotplug individual luns anyway.
How does hotplug/unplug work in the context of usb-bot ?
AFAIK we need to be able to run
device_add usb_bot drive_add file... device_add scsi-hd
And the reverse, to unplug it, if we're to have feature parity with usb-storage.
Hot-unplug is easy. You can remove the usb-bot device which will also remove all child devices. Hot-plug doesn't work at the moment, and I don't see any obvious way to fix that properly :-( We need some way to hotplug a *group* of devices (usb-bot + all children) as usb-bot itself is hotpluggable but the individual scsi devices connected to it are not. I could allow hotplug on usb-bot as workaround, then you can do stop device_add usb_bot device_add scsi-{hd,cd,whatever} cont but that would be more a gross hack than a solution ... cheers, Gerd
