Another immediate option for your customer would be to replace the SCSI controller with the VMware Paravirtual controller. With the SUSE guest properly shutdown, edit the VM settings, expand "SCSI controller 0" and change the type (pull down menu) to VMware Paravirtual. A patch has been prepared and tested that changes that warning message to a debug message. It will not be visible at the default tools logging level. The patch is applicable to source drops for open-vm-tools 11.0, 11.0.1 and 11.0.5. It is available at: https://github.com/vmware/open-vm-tools/tree/stable-11.0.5-suse-bug-1162435/open-vm-tools Commit: https://github.com/vmware/open-vm-tools/commit/4ee0bd3c8ead89541ab7d196fb54e940e397420d
