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.

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

/********************************************************/ oneadmin@node016 ~]$ virsh -c one:/// Welcome to virsh, the virtualization interactive terminal.

Type:  'help' for help with commands        'quit' to quit

virsh # list  Id Name                 State ----------------------------------

virsh # /********************************************************/

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