    362 === Is is possible to monitor a raw disk with smartmontools running on a virtual machine guest OS? ===
    363 
    364 No. If a guest OS disk is configured as a raw disk, this only means that its sectors are mapped transparently to the underlying physical disk. This does not imply the ATA or SCSI pass-through access required for smartmontools. Even the disk's identity is typically not exposed to the guest OS.
     362=== Do smartctl and smartd run on a virtual machine guest OS? ===
     363
     364Yes and no. Smartctl and smartd run on a virtual machine guest OS without problems. But this isn't very useful because the virtual disks do not support SMART. If a guest OS disk is configured as a raw disk, this only means that its sectors are mapped transparently to the underlying physical disk. This does not imply the ATA or SCSI pass-through access required to access the SMART info of the physical disk. Even the disk's identity is typically not exposed to the guest OS.
