Hi,

I am using version libvirt on debian lenny from backports repository, version 0.7.6-1~bpo50+1, amd64.

Th functionality of "virsh net-edit" command is not very clearly documented, and I think it should change a configuration of a running network. But I see it doesn't. So, I want to add new host, for example:

#I have old configuration root@xxx:/etc/libvirt/qemu/networks# virsh net-edit default Network default XML configuration edited. #Here I added new line: new host definition

root@xxx:/etc/libvirt/qemu/networks# cat default.xml #Here I see that new line

root@xxx:/etc/libvirt/qemu/networks# virsh net-dumpxml default root@xxx:/etc/libvirt/qemu/networks# virsh net-edit default #Here I see exactly the old network definition

Is this behaviour expected?

If yes, how to just add new host on a running network?

net-dumpxml (also used by net-edit) by default shows the current config of the network. Changes made with net-edit on a running network won't take effect until the network is restarted, so net-dumpxml won't show the changed config right away for a running network. Libvirt doesn't support changing the configuration of a running network, so any changes will require a network restart with net-destroy; net-start. This should be documented better. - Cole
