same question @div8cn do you have resources for this?
And also does this work properly with BIOS or is the problem not specific to UEFI?

[div8cn]

This is a problem only under UEFI.

bus=SATA of uefi
bus=id of bois

[DaanHoogland]

bus=ide if bios

i guess
so do you have resource to work on this i.e. is the milestone 4.15 or 4.16?

[div8cn]

yes bus=ide if bios

I can do relevant tests, 4.15 or 4.16

[DaanHoogland]

I don't think i can spare dev resource for this @div8cn so I won't put a milestone on it for now.

Hi all, if nobody is working on this, I have a fix for attaching/detaching an ISO and deploying a VM from an ISO (because there's also a problem with this option). I'm still testing it, and when I'm ready, I could open a PR with the fix.
