Re: [Libvirt-cim] What is the current state of VM guest creation/modification, storage pools, and metrics in Libvirt-CIM?

I would imagine it would be done via some cheating in dom0, which would fake the PXE client action, download the kernel and ramdisk as specified and then launch the guest out of body (i.e. without a bootloader).

Dan suggested something similar. I'm not really familiar with either (a) the implementation of the data gatherer or (b) the profiles and classes needed to support metrics for a CIM client. Regarding the former, I would hope that the modules in the data gatherer can be loaded as dynamic plugins, which would mean that we could implement and maintain a data gatherer plugin in the libvirt-cim tree, and "marry" it to some of our other infrastructure. We would install it in the proper location on a system when libvirt-cim is installed, and the data gatherer would start to expose those bits. Regarding the latter, we could just implement the metrics ourselves as regular providers and not be dependent on the data gatherer at all. As always, I'd be hesitant to do something other than use a pre-existing framework for something like that, so we'd need to come up with a good justification for going this route. DM> One more question. Daniel Veillard mentioned someone may be DM> working on VM cloning capability. Do you know any details about DM> it or who might be working on it? I'm not sure what you mean exactly, which probably means my answer to your question is "no" :)... However, you should probably ask the libvirt mailing list[1].
