In fact -uuid and -smbios table1,uuid= are completely identical from qemu's code point of view since both of them set the same global variable qemu_uuid. Currently there is not problem using both of them (with the same uuid value of course) and I do not think this will change in the near feature, so fixing libvirt to use only -smbios may be not the most urgent bug to fix. -- Gleb. -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
