There's got to be a simple way to attach an ISO to a KVM guest. I just haven't yet discovered it. I've tried adding the following stanza to my guest XML file, under the <devices> stanza and starting the guest: <disk type='file' device='cdrom'> <driver name='qemu' type='raw' /> <source file='/etc/libvirt/qemu/isos/kvm1.iso' /> <target dev='hda' bus='ide' /> <readonly /> </disk> But I get the following: error: Failed to start domain rhel6guest error: internal error process exited while connecting to monitor: char device redirected to /dev/pts/3 qemu: could not open disk image /etc/libvirt/qemu/isos/kvm1.iso: Permission denied A perms issue should be easy to address one would think, but I've tried every possible combination of perms changes including 777. Changed ownership from root to qemu:qemu (though I'm running as root). I'm not running SELinux. Anyone have any insights on how to mount a simple ISO into a KVM guest? Both at build time AND while the guest is running? Thanks Jeff
