I presume you are using the Xen API c-bindings? I see such messages as
well. Xend is not populating these fields and hence the c-bindings
complain when unmarshalling the on-wire structure. I have been ignoring
them unless it is a field of interest - in which case a patch is sent to
xen-devel :-).

Regards,
Jim

yes it is from Xen API c-bindings
in guest_metrics there are some interesting things

One more question

How I can get actual cpu usage for some guest machine?

See VCPUs_utilisation field of class VM_metrics. I have not yet used
this class, so not sure about the status of implementation.
