Yes, the user build the machine using the command line and monitor (or, in 2017, the machine configuration file), then turns on the power. Command line options are the parts lying around when we start.
btw, -drive needs to be separated: -controller type=lsi1234,pci_addr=foobar,name=blah -drive file=foo.img,controller=blah,index=0 -drive file=bar.img,controller=blah,index=1 Drives to not have pci addresses. -- error compiling committee.c: too many arguments to function -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
