Problems importing Xen VMs with 4.14.2

Community Support
1

Hello. I am trying to use OpenNebula to import a wild VM (plotter) in a hypervisor called hypervisor001 (id 14)

The Wild VMs tab in sunstone for this HV (and others) is empty.

The onehost show 14 does show the wild VMs (output below). But the onehost importvm command does not work:

oneadmin@onemaster001:~$ onehost importvm 14 plotter
No importable wilds with name 'plotter' found.

Have plasted some useful outputs below:

onehost show output:

I have been digging further. The poll script for Xen does not work with Xen XM toolstack (or XL configured with sxp output format), as it expects to parse JSON output which is a XL-feature (and only from Xen 4.2).

It should be indicated in the documentation that the feature is only available with XL and modern versions of qemu-img (older ones won’t provide json output either).
