 +=== Can't import virtual machine due to existing uuid ===
 +
 +If you have multiple webhmi images in Virtual box, you can encounter this error, becuase virtual image being added usually build based on previous one, so it may have the same uuid for itself or vdi files. For this, you can detect 
 +which machine has colliding uuid with the VBoxManage command line tool and in the virtual storage manager in Virutal Box.
