So some rocks are radioactive because they have radioisotopes in their nuclei. Also they may have radon gas trapped in their crystals if they are igneous rock. They could also be radioactive due to the fact that the atom of the rock is unstable.
Connecting USB Devices Manually. Choose VM > Removable Devices to connect specific USB devices to your virtual machine. You can connect up to two USB devices at a time. If the physical USB devices are connected to the host computer through a hub, the virtual machine sees only the USB devices, not the hub.
1 Mount the USB drive using USB passthrough to a 2nd VM on the same physical server. 2  Share the USB drive from this VM using NFS. 3  Mount the NFS share from ESXi as network storage. 4  Copy the VM files across directly from one store to the other using vsphere client.ailing that, you can use USB passthrough to assign the attached USB device to a Windows VM, then use the vSphere Client from within that VM to save the directory to the USB device via the Datastore Browser.
