KVM guest fails to read the physical DVD-ROM media in the host

Issue

• When a KVM guest tries to read the physical DVD-ROM media in the host, the following error may occur and the
  guest cannot read the host's DVD-ROM.

  attempt to access beyond end of device
  sr0: rw=0 want=3904520, limit=2097148

  When this issue occurs, the df command shows the correct size in /dev/sr0, but the lsblk command does not.
