hello
I'm currently using libvirt and opennebula. I have installed the libvirt
with the driver of opennebule "ONE" and I test the installation.

but I can not see the list of machines that run in the cluster node (Xen and

I want to know if this is a problem of configuration files ( libvirtd.conf and
oned.conf).
can you help me to overcome this problem
thank you

The OpenNebula driver is currently not really maintained by someone.
I took a look at the OpenNebula driver code and I understand now why
it doesn't work as expected.
The driver keeps and internal list of known domains, but this list is
never initialized with the already existing domains, that's why it
doesn't list your already existing domains. The list is only altered
by libvirt's define and undefine functions.
I think that the driver should not cache this list, but it should
request the list of existing domains from the OpenNebula daemon each
time it needs it. This way it'll always be in sync with external
changes.
Once the internal list is replaced by a lookup function the rest of
the driver should just work.
I don't have a OpenNebula setup at hand, so patches welcome :)

thank you very much for your reply
As you said libvirt see only machines that set. in fact I would like to know
what part we modify to solve this problem.
I also want to know if the driver of opennebula supports migration or not
thank you

As I said the driver keeps an internal list of domains it knows about.
See src/opennebula/one_driver.c for driver->domains, that's the
internal list. This list needs to be replaced by a function that asks
the OpenNebula daemon for the list of existing domains each time it
needs this information. Basically this parts of the driver need to be
rewritten in the way the ESX, Power Hypervisor and VirtualBox drivers
work.
Regarding migration, this is not implemented yet for the OpenNebula driver.
