Get all the VMs running on the vCenter, not just specific hosts. you're connecting via the ESX driver (using the type 'vpx' in the URI schema), which from libvirt's point of view is client-side only which means that we use the driver to talk to the vCenter. When querying the list of machines, I would expect the vCenter/ESX server to return the list of all VMs on all vCenter nodes, if not so, then either our driver needs to be updated to reflect the changes or the backend API (the ESX server/vCenter) doesn't support this feature and you'll need to query all the nodes manually. I never tried using the esx driver, so that's just my understanding of how I think things are supposed to work, i.e. it's fairly out of libvirt's reach, since we just call the corresponding remote APIs the ESX provides, there's no daemon we can control.
