    Incompatible device backing specified for device '1'  error migrating Linux

    jaygt Enthusiast

      I am receiving the error Incompatible device backing specified for device '1' when I migrate a Linux guest "cold" from a 2.5.3 host to a 3.0 host. I have successfully migrated two Window guest from the same host to the same destination 3.0 host with no problems. I appears to be with Linux guest only.

       

      I have tried to manually changing the SCSI controller with no success. I have reveiwed the VMkernel logs and found the following error:

      Jul 31 16:53:23 spesxtst vmkernel: 17:06:41:55.885 cpu0)VMNIX: WARNING: Mod: 376: Minor version mismatch vmnix (0x1c0001), vpxa (0x1c0000)

       

      Has anyone else encountered this problem?
