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 On Thu, 6 Dec 2018 at 18:25, Yiping Zhang <yzh...@marketo.com> wrote: > Hi, All: > > I am working on a script to handle data disks.
