+
+I use [virt-manager] to manage VMs. These are the steps to do that when creating the VM:
+
+1. Create the VM and at the last step choose "Customize configuration before install"
+2. Click on the "IDE CDROM 1" tab and change "Disk bus" to SATA
+3. Then click Apply, and then Begin installation in the top left.
+
+After that the VM installed successfully.
