Ubuntu Virtualbox Cannot register the hard disk fixed

Sunday, April 27, 2014 12:55 PM 0 Comments Cannot register the hard disk , ubuntu 14.04 , virtualbox

i found this problem after upgrade from Ubuntu 12.04 to 14.04. the problem is  cannot register the hard disk UUID because UUID already exists.



We need to change hard disk uuid from command line

vboxmanage internalcommands sethduuid vmimage.vdi

After change hard disk UUID, We need to add vm image to Virtualbox





Done. Happy!!!
