Hi Flex Liu, So far, I have been unable to reproduce the failure in-house. I have tried SLES 12 SP4 fresh installs of desktop vs. server partitioned vs. LVM I did the testing with an internal 11.0.1 tools build, but the only Linux difference between 11.0.0 and 11.0.1 was cleaning up a minor memory leak. Since the errors that you reported show problems against "/dev/sda2" that sounds like the default use of disk partitions. Is there some other disk configuration being used on the VM showing the excessive warning messages? What is the virtual disc controller in use on the problematic system? Thanks John
