When I try to add SATA device to a virtual machine this device does not appear in the list of devices inside guest OS and Parallels Management Console suggests to reboot the virtual machine to apply the changes:
The guest OS does support SATA hotplugging and after the restart I am able to add new SATA devices without reboot.
SATA hotplugging feature requires SATA controller inside virtual machine. To be able to use SATA hotpluging feature the virtual machine must have at least one SATA device assigned.
Reboot the virtual machine after adding first SATA device to it or use SATA interface for CD\DVD-ROM and hard disks while creating the virtual machine.
