I found the problem...
When I close one of my VM the log message stop. I look in the log of this VM and I found this:
Jul 26 13:34:17.773: vmx| CDROM-LIN: CDROMHostGenericSendCmdAIOCallbackSGIO: Unexpected error: Inappropriate ioctl for device (6402)
Jul 26 13:34:17.773: vmx| CDROM ide0:0: CMD 0x5a (MODE SENSE(10)) FAILED (key 0x2 asc 0 ascq 0)
I look the VM setting and CD/DVD was unmanaged. I delete it and recreate it and the message gone.
Thank
