Dear ladies and gentlemen,

I have two questions:
1.when I take a picture within the virtual machine (via notebook Webcam),is it secure or will the host make any copies of this picture?

2.Are documents, videos or other data handled within the virtual machine stored at any point in the hostsystem so others could open them in this host?

The guest files are isolated from the host files, unless you want them to be shared. The host does not have access to the guest and the guest does not have access to the host, by default.

But, if someone has access to the host, they could launch the VM and get access to the guest. You can prevent this by having a password for the VM. See Chapter 9.31. Encryption of disk images. Read all the Chapter CAREFULLY or you might lose your data.
