Hi again, I added another boot options to my running domain, like this: # virsh edit leon.i-tux.cz <os> ... <boot dev='cdrom'/> <bootmenu enable='yes'/> </os> (Note: "dev='hd" was already present) Right after :wq (vim commands) -> # Domain leon.i-tux.cz XML configuration edited. Now when I did "virsh dumpxml leon.i-tux.cz" these new boot options are missing in output. But "cat /etc/libvirt/qemu/leon.i-tux.cz.xml" shows me these new options and "virsh edit" also. Is it some bug or normal behavior? I also noticed that these options disappear after restarting libvirt daemon - but only from "virsh edit", not from /etc/... xml file. I would like to do some kind of backups of my domains thru dumpxml :) Maybe the best way will be to backup all in /etc/libvirt. Thank you, Jaromír.
