I'm familiarizing myself with a server that a previous (no longer available) system admin had set up. He had set up CentOS 7 with a variety of packages. One of those packages seems to be libvirtd, which is a new service to me, but apparently it has to do with managing virtualization.
That said, I can't see any indication of virtual machines running on this PC. There's a virtual networking interface "virbr0" associated to this service, but it has 0 packets, according to ifconfig.
Is it possible that the previous sysadmin was just mass-installing packages or even some predefined bundle of packages and this just got installed but is not actually in use? I don't see any telltale signs of any virtual machines running on this server, but I hate to assume that, or assume that it's not somehow a dependency for some other app.
Is there someone who is experienced with libvirtd who could provide some different ways to check to see if it's in truly in use or needed for something, so I can work on removing it if it's unnecessary?
