I get lots of e-bills (utility, telephone, Internet, mobile, cable and so on) in a PDF format for my small business and I need to forward those to my accountant. However, all PDFs files are password protected. I don’t want to share my account password with anyone to just open my bills. Evince is a PDF document viewer capable of displaying password protected files but it cannot remove the password. How do I remove a password from all PDFs under Ubuntu or any other Linux distribution in a batch mode?

virt-manager requires GUI locally and it is slow. On other hand virt-install is a command line tool for provisioning new virtual machines using the “libvirt” hypervisor management library. The tool supports both text based & graphical installations, using serial console, SDL graphics or a VNC client/server pair. The guest can be configured to use one or more virtual disks, network interfaces, audio devices, and physical host devices (USB, PCI). You can use the virt-install to create virtualized guests as follows to install FreeBSD or CentOS.
