Are you talking about a windows guest? Installing the vm with virt-install, use --disk path=/path/to/disk,device=disk,bus=virtio \ --disk path=/tmp/virtio-win-1.1.16.vfd,device=floppy,perms=ro The first line specifies the disk for the vm (e.g. C drive), I usually use an lvol. The second line specifies the path to the virtual floppy drive with the virtio drivers. For xp, you cannot use the cdrom/.iso version of same, the xp installer accepts only a floppy (F6, install 3rd party drivers). Newer windows versions may be able to deal with an iso. Digimer's tutorial is well worth a read, even if you end up doing something entirely different. https://alteeve.com/w/2-Node_Red_Hat_KVM_Cluster_Tutorial
