Hi all,
as you surely know, after changing some domain parameters via libvirt
(ie: NIC type), the guest need to be shutdown and restarted. A simple
reboot will not be sufficient, as libvirt will not launch a new qemu
domain (ie: the same qemu process will be in charge to start the new
guest instance).
It is possible to configure libvirt to start a new qemu domain on guest
reboot? Can the <on_reboot> domain attribute be used for implementing
something similar?
Thanks.

With the current impl this is not possible. From a technical POV though
it is possible to extend libvirt to have a <on_reboot>recreate</on_reboot>
option which would kill QEMU & recreate it with the new config. Basically
just needs someone motivated to write the code...
Regards,
Daniel

Ok, thanks Daniel.
