I don't think there's a way to step into virt-manager's process of defining domains. However, you can use virt-install directly instead. It can just print the XML instead of defining it in libvirt. You can take this document, modify it and then 'virsh define ...' it. What you are seeing is a bug that is fixed already. > > So, can i delete the ioh3420 only by changing the code?info: i use the libvirt-2.0.0,virt-manager create doamin succeed;when i update to libvirt-3.2.0,the issue above happened. qemu is 2.3.0 Also I should point out that libvirt-2.0.0 is two years old release. Nearly. Upgrade if you can. Michal _______________________________________________ libvirt-users mailing list libvirt-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvirt-users
