Re: what happened to /dev/xvdd in my instance?


That's a funny - and true observation - I also reproduced the same - during
hotpluging disks, and also during booting instance with already attached
disks - BUT inside VM, there are vda, vdb, vdc, vdd disks (no vde, as can
be seen in VM XML)

I though it might had something to do with ISO files, but these are (as it
seems) always attached as IDE (sdc in my case/test).

I'm still assuming this is done due to some reservations
