Someone before me in my current job created a couple of VMs in AHV with IDE bus type for their disks instead of SCSI. Just a quick glance of the documentation I found this:
AHV does not leverage a traditional storage stack like ESXi or Hyper-V. All disk(s) are passed to the VM(s) as raw SCSI block devices.
So my question is, why would someone decide to create IDE disks? Am I missing something? I know it’s common practice for CD-ROM drives, but not storage disks. No wonder I noticed a really bad performance on those servers recently.
