ATA controller and Hyper-V "synthetic storage driver" handle the IDE disks devices ( but not for the CD-ROM) Re: Hyper-V on FreeBSD

Hi!

> prevent default OS driver from attaching to emulated ATA controller when Hyper-V

 Disable both primary and secondary ATA controller prevent use CD-ROM device in VM ( guest)

Because "synthetic storage driver" not handle CD-ROM devices
( IMHO, even more: Hyper-V host work with CD-ROM only as "PCI bus" device)
