I'm going through the installation process using virt-manager which I will install a virtual Red Hat machines with on my physical host.I have the image iso on the host and mounted it on /media/cdrom.Red Hat lists four installation methods.Local CD/DVDHard drive NFS directoryURLMy first option is to use CD/DVD, although I end up getting a disc was not found in any of your CDROM drives.For hard drive it lists sda and sr0. We also have a NFS directory, which I can try if I don't get it going with the first two options.
