there is a other device with the same UUID. It is a device that shouldn't have anything to do with one that I'm trying to mount. It is possible however that the the device I'm trying to mount was made by copying the first device. Would this cause the UUIDs to be the same?  The devices are from two different virtual machines but, if I remember correctly, one was made by copying the other (as I guess people do when cloning virtual machines).

I have other devices wuth the commons UUIDs so it is guess clear that I made one of the virtual machine by cloning the other.

e8eb39b2-9425-4181-a5c0-687ee122704a

Do I need to change the UUID of the devices of one of the virtual machines? I must admit that I do not know who to do that.

thanks
Stuart
